1. What happened to the Kelvan invasion? 2. Where are the Vorta and the Jem'Hadar now? 3. Is Saavik still alive? 4.Will Qo'noS still be around?

At the end of Picard S3 Q shows up in Jack's quarters I believe the first episode of Legacy should start with that exact sene and the camera pan over to a flash and Wesley appearing. He then proceeds to tell Q to leave his Brother alone and they both disappear leaving Jack speechless which starts a long standing story arc through the series. They can also bring back Q's son to pass the torch. This also opens up more of how the Continuum and the Travelers interact.

I think Garak would be a great addition to Legacy as Castellan of the Cardassian Union

One of the things about Star Trek I find perturbing is how the Federation hasn't met other groups like The Federation. It's a big galaxy and trek has populated it with a lost of species. As the Federation spreads its influence it could encounter an alliance similar to itself, and not hostile to it. It doesn't make for good conflict based story lines, but it could be good reflection storyline.

The intervention of Wesley Crushed as a Traveler could help explain how a lot of things transpired the way they did. We've gotten to know the Q a bit, but we still have Travelers, Organians, Dowd, Metrons, Species 10C, and several others, all vastly more advanced than any Federation species, and all still largely unexplored. And I'd like to know the origins of the whale probe and the Doomsday Machine.

Benjamin never truly said goodbye to any of his friends... especially his son, Jake. We at least deserve closure to this story plot.

T'Pol. I miss T'Pol. She gave a very unique and informative view Vulcan culture. She was one of the best characters.

The Return fo Sisko and More DS9 will always be the dream. While we have lost Nog and Odo, seeing the rest of the cast would bring me so much joy. Give us Season (8) of DS9.

I always wanted the follow up to Conspiracy. It is my favorite next generation story and was left on an unresolved cliffhanger.

I think that Species 8472 could be more for Prodigy, given that they're heading towards the Delta Quadrant.

Just give us Legacy, SNW, and LD. That's all we need.

What I really want to see is more Weyoun. I love Jeffrey Combs, I want Weyoun to serve as Dominion ambassador to the Bajor, to the Federation, to the Cardassians, even the Klingons. Just every time we see a new location, there's a Weyoun there.

Way back when I wrote a concept for a post Voy series, I had Sisko living on Bajor serving as Federation Ambassador, implying he was only gone for a couple years. His appearance would be more a cameo for the pilot.

I was upset with an article I read yesterday. It states that ST Legacy will not happen. The budget isn’t there due to the Section 31 movie and Starfleet Academy. Even Matalas walked back on it. I don’t care for the Starfleet Academy and I’m not the only one who thinks so. Fans agree with your list. I want to know how many Hirogens made it to the alpha quadrant after hearing an Alfa was hunting Admiral Picard. There’s still plenty of stories to tell. We should band together to make St Legacy happen.

I enjoyed the callback to Thomas Riker in Lower Decks, an actual appearance in live action would be cool.

I’m all for this “Legacy” show you always talk about however, Seven and the Crew of the G that ended Picard deserve to have their own complete series separate from whatever “Legacy” show might be created. Jeri Ryan deserves that captains chair for a multi season show not just an arch of a tie up loose ends series.

With regards to exploring the gamma quadrant, we could also see the rediscovery of the USS Columbia. If I'm not mistaken in one of the books, it's found in the gamma quadrant after going MIA? That would be quite cool to explore

Someone needs to write a story on how baseball became popular again! It’s was all but extinct in DS9 but Lower decks and Picard indicate the baseball and the London Kings are a big deal in their timelines.

I've always wanted to see how the Vidiians are doing since the Think Tank, apparently, cured the phage.

What if…. It comes to light, that Elnor is the secret son of Sela. Hidden with the Nun’s, while she went into hiding.

Regarding Sela, you mentioned STO's usage of Species 8472 - STO also did an amazing arc with Sela, even bringing back Denise Crosby to voice her. I would LOVE to see Sela return onscreen in a manner similar to what was done in the game.

i want a star trek prometheus series or movie! that ship was fire with mvam!!

I could see Thomas Riker back, living in Alaska and living a rural lifestyle, not because he has to go because he chooses to. Something a kin to. Rambo in the fourth film like he’s a man who wants to be left alone because he seen enough over the years.

Really hope this gets greenlit. Star Trek needs to move forward and add more to the world

I NEED to see Quantum slipstream/Transwarp drive(s) implemented on all Federation ships! It'd be great for getting around the problem of how long traversing the galaxy at warp speeds takes.

Although a quite hated episode, I´d love to see TNG "Conspiracy" revisited. Might even tie them in with TOS "Operation: Annihilate", as some of the "features" of both aliens are somewhat similar. Mind control (through excruciating pain in TOS episode, more subtile in TNG, something like an "evolution" of the species and methods), phaser resistance, etc. Star Trek Online´s storyline also has some damn good ideas. And the most important: has Kim became a captain afterall? 🤣

The aftermath of the Dominion War has the potential for tons of great stories. You can do stories about a shift in the balance of power in the Alpha/Beta Quadrant. Powers that were not involved in the war could take advantage of the Klingons being weakened by war. Caches of weapons and technology from the war could go into the black market, resulting in more piracy and crime. Minor powers could even recover advanced technology from the wreckage of battles and lost ships. There could be debate within the Federation about Starfleet. Worlds less affected by the war would want Starfleet to disarm while worlds that were invaded would want a more militarized Starfleet to protect them. You could also do stories about the Federation trying to maintain the alliances they built during the war, trying to set up joint missions with the Klingons, Romulans, and Cardassians. Starfleet would try to go back to diplomacy and science and launch a new age of exploration for the Federation.

I really enjoyed Sela's story in Star Trek Online. Tying the fallen Romulan Empire with the Iconians was a really good story arc.

Sisko was my favorite trek captain, and a follow up to his story that wrapped up his arc with the prophets would be awesome! That could tie in with a 8472 story too, that Sisko and the prophets are engaged in.

What was coming through the wormhole at the end of Star Trek Picard season 2 that needed the borg to defend the galaxy against? Will the synthetic life forms from Star Trek Picard season 1 return to liberate the synthetic life forms of the federation?

Picard season 2 and the Stinger for season 3 really makes me want to see something involving Junior there. Honestly, Junior popping up in the end to have some fun there could be hilarious

I don't think we'll get Brooks back. The DS9 writers want to tell the story of his return and Brooks doesn't want Sisko to be an absentee father. If they told a story where we learn Sisko returned years ago and was living on Bajor with Kassidy in the house he was building different story.

To be quiet honest you left one out. The bluegill species from next generation and enter through the mouth or neck. From the episode conspiracy. That would be a good dark story arc to follow. Are they related to the flying parasites from the original series that attached itself to spocks back? Are they planning revenge against star fleet? Or did they go and take over another species? Huge hole left open from that classic next generation episode. Only other two i can think of, is from doomsday machine from the original series. Are there more? Who created them and why? Last one would be the whale probe. There a unique story there that could play out

There are two arcs I want to see explore; one is the Vulcan-Romulan reunification and Harry Kim, I want to know what rank he is now.

Maybe this has been touched on, but what about in the TNG episode "Conspiracy" where those creatures were attached to their necks. At the very end, a beacon was triggered, and then.. nothing. What happened to those creatures. Maybe not a full-on storyline, but a part of the story, at least.

Picking up on Garak's story is my #1.

What about Borg Jurati and her watching over the mystery transwarp conduit?

I really want to know what happened to the Malcorians from the episode First Contact. It's been about 30 years in universe. Ps Neral was Proconsul, not Preator.

I hate to be that guy, but I believe that Sisko's few voice lines in STO were just lifted from DS9 rather than being specifically recorded for the game.

Nog as an officer. It is sad the actor for him is dead. The Nog character feels under appreciated and forgotten

I know it's your thing, but I never cared much about Sela and don't feel there is anything needing resolution with respect to her. Thanks for a great episode.

playing with alternate time lines would be fun and a great way to bring back characters who had a less then favorable outcome in the prime time line but If I had to follow up on characters from the prime time line I would go with 1. Naomi Wildman 2. Timothy from Hero Worship 3, Marissa Flores from Disaster 4 Miles O'Brien and Julian Bashir and the O'Brien family 5. Pel the Ferengi 6. Tosk 7. The Hirogen and the holograms 8. Demora Sulu 9. Q Junior 10. The Equinox crew 11. those alien s from Conspiracy 12 Jason Vigo 13 Clare Raymond 14 Madge Sinclair 15 The Voth IMO Sela, Thomas Riker, Lore, Shinzon, Duras should have all been in an episode together how to make that happen is not my problem to work it out, I just would have preferred that interaction over some of the others we did get. and if you want to make it extra spicey add in Seska, an early version of Seven, Joran Dax, Sybok, Garak IDK pull them from time or an other universe or the Hollideck Just to have this union of evil or morally grey characters. Speaking of Holograms , we could also give modal emitters to holograms of any one have basically any character team up we want. or it could be a Q episode or an illusion made by a planet that wants to test good vs evil. Go back to The Savage Curtain and find out who one of the other captains calls a hero. I would also love to put William Shatner and Chris Pine in an episode together threw time travel or cloning or reverse aging or rapid aging or some thing

Would love new series with seven and Raffi and jack and such

Regarding Thomas Riker, my bet is we’ll see him again in season 5 of “Lower Decks” teaming up with William Boimler at Section 31. Makes perfect sense; who better can understand the struggles of being a transporter clone living in the shadow of the original than…another transporter clone?

I would actually love to know more about the Enterprise when Robert April was the captain, it would bring us in a time that Star Trek hasn't quite elaborated. But I think some Short Trek are absolutely necessary for the other Enterprise that we haven't quite seen on-screen: (The Nx-refit, The Enterprise-B, C and F) would also be good to include the J

How about the TNG episode "The Chase", where they find out all the humanoid species in the galaxy shared a common genetic origin? Seems like a hefty reveal to be completely ignored for the last 3 decades. I'm not entirely sure how that could be brought back, but I'd like to hear something about it again.

I think selah should have been on deep space nine maybe season 7 or late season 6 when the romulans entered the war she could have been the romulan Commander for all romulan forces in that area of the war and then ask for neelix on Star Trek Voyager I think an episode would be in order for legacy where the captain 7 in the crew of her enterprise somehow ends up in that sector where neelix is colony is at and a nice reunion between 7:00 and neelix and neelix being surprised how far seven has become to become the captain of the flagship of the federation

a plot thread we need for Legacy would be need to be that of of Jack and Q and the true nature of Yvette Gessard Picard's depression and death, culminating in a realization that Yvette was of Q and as her children where part human, they where seen as an experiment by the Continuum, but they did not make it easy on Yvette in inflicting upon her the all sorts of nightmares and depression that the professionals couldn't ever fix, Picard was let out into stars as part of this test, but when René Picard started to manifest Q-ness the idea of another Picard out among the stars was to much for the continuum and both René and Robert paid the price when the continuum started the fire, and much like Yvette's depression, no amount of advanced fire suppression could stop the fire until it had done the job it was assigned. Q (John de Lancie) never felt right to what the continuum did to the Picard family, but was powerless to actually stop them. we could tie in Trelane into this as well, as being the Q the continuum has tasked with all the dirty deeds, I can see Trelane being played here in Legacy by Tom Ellis

Species 8472/The Undine are one of the coolest aspects of Star Trek for me and I’d love to see them again, also please more Garak

A Legacy series with Archer finally being revealed as Future Guy would be awesome. We unfortunately lost Manny Coto, but his ideas could finally be used. The TCW could be used as a basis to bring back many more characters.

I just wanna say thank you for remembering the Ocampa!

Two things of note: 1...I would love to see Star Trek: Legacy as an anthology series with a different story from a different series each episode. 2...I think the parasites from Conspiracy need to be revisited!

I think Wesley needs his due... the last novel ending the extended Star Trek universe timeline from Nemesis onward would be the perfect one to turn into a limited series, giving us a Wesley as Traveler buffet! And the very storyline involving multiple parallel timelines would be the excuse why it doesn't follow any of the current series timelines, and that could be incorporated somehow, I'm sure!

Certainly some interesting and powerful species in the DQ to explore, some as potential good guys and others as antagonists. I can certainly see species such as the Hierarchy and Devore expanding quite militantly, and likely the Hirogen starting to re-unify.

Here's a novel idea: a totally new Trek Series! No "this person from this show" and "that person from another show", no kids from established characters, no follow-ups of stuff from previous episodes; just a new show. A new ship with a new crew, going on a new mission to explore new worlds.

I really want to see the Dominion again(not rebel Changelings alone), perhaps a Vorta observer. I want Sisko back, even if just to finish his story. More Garak. Strides towards better relations with the Xindi,( perhaps discovering a lost Xindi Avian colony) Tholians, Gorn & Ferengi. A new threat from the Skorr as religious fanaticism has been an issue before with them and could arise as a new threat. I'd like to see the Interstellar Concordium become canon. There's just a lot of potential for a Star Trek Legacy.

While the gamma quadrant is ripe for exploration, a good starting point for legacy would be back in the delta quadrant to forge new alliances and bring more species to the federation. Season 2 could be venturing to the gamma quadrant and if they're out of plots, could go to do the temporal cold war.

Controversially, DS9 is my favourite trek series. I would take anything that furthers old stories because picard played the nostalgia card BEAUTIFULLY so i would love to see ds9 characters again.

You’re spot on Seán! Each of these entries deserve further development. All we can do is hope!

I would like to see Commodore Oh return and developed properly.

I want to see some exploration of Jurati's Borg.

This sort of discussion is exactly why we need a TrekCulture Discord as youtube comments are NOT practical for this kind of discussion. Just the ability to add source links and include images for illustrations of points. You are severely limited on these things with YT comments.

Hey, I would very much love to see more of the Breen too

They could do whole episodes with the Time travel technology Guardian of Forever - if they could isolate the Retro Causality Effects. Guessing branching Time Line or Alternative Universes. Pre-Carl manifestation temporal wars.

Legacy should be an anthology show. Story’s past present and future. Different ships, planets and alien cultures new and old. Pick up old and new plots lines. Flesh out backstory’s. Show us Star Trek history we’ve heard about or never seen? Give us an entire episode of the battle at wolf 359 or show us the Romulan exodus from Vulcan

I think that a story involving the Delta Quadrant would be good for Legacy. Seven would have plenty of knowledge of the species there. The over all mission could be to establish a new Star Base in that region. The cast could then include appearances by several Voyager members in supporting roles at the Star Base. The role of the Enterprise crew is to spearhead further exploration of that region. So, we will see the return of several species previously encountered. Some friendly and some enemies. This would also give reason to expand beyond the current 10 episode mold back toward classic longer seasons. Maybe 20 episodes max?

More Garak yes please! 😊

You're forgetting Sela's arc on Star Trek Online. It got answered pretty well.

Fate of Sisko, who takes over the Cardassia after the dominion war are both sorta explained in the IDW comics. They also show where Sela was between Voyager and Nemesis. Sure the comic isn't canon, but so is(n't) the STO, which was referenced in the video.

What about the Reapers at the end of Picard season 1? Will they never be mentioned again? Are they some eldritch, Lovecraftian horror, too unspeakable to think about?

If Enterprise comes back in any way shape or form I will be ecstatic

6:44 tbh, in STO, which this part is often forgotten, Thomas married and HAD a son named Joshua Riker with an unknown woman, he’s Technically William Riker’s Nephew but could be mistaken for his son without knowing first. After the collapse of the Old Cardassian Regime at the end on the Dominion War, the prison colony where he was at, Lazon II, fell into neglect and was mostly forgotten about, using his leadership skills, Thomas was able to build a community out of the old Prison, married another one of the inmates, and had Joshua with her. unlike in STO, Thomas wasn’t forgotten about completely, and i think he was retrieved by another California-Class ship from is home. I bet while away he negotiated for Supply runs and assistance for his people and colony on the planet. 6:51 In a Recent Addition to Beta-Canon, Sisko HAD Returned Temporarily to deal with a threat that was posing not only a danger to the universe but a danger to the prophets aswell, and he had gone to Starfleet to Recommission him and to seek assistance, he was introduced to his daughter, Sarah Rae Sisko, and was temporary given command of the USS Theseus, a Refitted Discovery-Class Starship, the Discovery-Class was an old failed 23rd century Multi-purpose Plug-&-Play modular Cruiser that was always experimental, so all commissioned class members had the “NX” designation with the Theseus’ number being “NX-1987”, but the design was only a failure due to the technology of its time, so after being Decommissioned the Theseus was put in the Reserve and stored at Qualor II, and was later retrieved in the late-2370’s by Captain Montgomery Scott to be rebuilt into a Testbed for the Odyssey-Class. The Theseus, although not planning to be, under sisko’s command was Reactivated in full and helped him save the galaxy.

Regarding the Temporal Cold War as a storyline unifying all of Trek, I really like that idea for Star Trek Legacy since the video game, Star Trek Legacy, was also about a story unifying all of (then current) Star Trek. Granted in the game it was an extended Borg storyline but it Started with Enterprise, moved to TNG, ENT, DS9, Voyager, then circled back to Nemesis-Era TNG with the Enterprise E

The race from Schisms actually appears in Star Trek Online, as one of the servitor races for the Iconians. Playing this storyline would be epic in a show.

Look i get everyone is in love with the old trek and old cast but cmon at this point this is just pure nostalgia bait. one of the reasons i like 90's trek is that each show was able to stand on it's own without relying on nostalgia or continuation from other shows. I love lower decks and prodigy and strange new worlds but face none of them have been able to stand on their own. Give us a show to stand on its own and allow it to grow and progress into something new but respect what came before but not over rely on it.

I think it would be interesting to have a show from the perspective of a mercenary who has no desire at all to join the Federation. They’ll help when people are in need, but has some very big issues with the Federation’s militarization, philosophy, etc. As it stands, Star Trek’s outsiders that reject the Federation always also reject space travel and being moral, and tend to be happy just being on one world.

Earth-Romulan war anyone? as quite a bit of the relauch book series have been rendered not cannon due to several of the current series. Also more exploration of the AI control through out the modwrn timelines, could be interesting Also would be fun to see which events/episodes would have been classified, thinking that end of Picard season 1 was probably made classified

If your acknowledging ST online then the question of Sela was answered, she declared herself the Romulan Empress between 2403 and 2409, was imprisoned by the Iconians and rescued in 2410, subsequently imprisoned by the Romulan Republic before escaping and being re-imprisoned several times.

I think a perfect thread to revisit would be the Vaadwaur. They were revived because of 7! Janeway said the repercussions from this could be catastrophic. And well...

This may be a controversial take on the subject, but I think Captain Sisko is okay staying gone, not because he isn't great, but because that's life. How many of us have lost people and never had the chance for closure or to say goodbye? It is a heartbreaking reality of existence, that we lose people we care about and don't get a fairytale farewell. It might be an even more poignant story arc to explore his friends and family coping with his loss, so many years later.

My own list of things I'd like to see revisited in ST in one form or another: The mobsters from " A Piece of the Action". Did they ever develop warp technology from McCoy's tricorder? Why didn't the Federation ever try to follow up on the warp engine the size of a walnut from "I, Mudd"? How are George and Gracie and little Groucho doing since the whale probe? Did Oz give anything to the Tinman that he didn't already have? And yes, where the hell was Wesley during Picard Season 3?

I just a real cannon update about the voyager crew. Legacy can give us that by bring back Janeway and assign Tom’s and torris daughter to the the ship, Sikos kid as well.

I think the most important storyline to explore is the fact that there is Jurati's Cooperative has temporary federation membership - that's got to cause some sort of controversy. On top of that, the overturning of the Synth ban would likely read to a surge in Mutant/Augment/Illyrian rights activism. Especially considering that, by this point, the rule has been broken on several occasions (Bashir, Dal, Icheb, Una, Sarina) without issue and that the Federation has been using an Illyrian as a literal poster girl for recruitment.

Revisiting the Founders (and casting Remy or Tessa Auberjonois as an evolution or descendant of Odo) would be beautiful. And _Discovery_ could do it too. But, no knocks against Sela, the #1 thread that the canon needs to pick back up is the fate of The Sisko.

Bringing back the story of Star Trek: Enterprise in an animation would be nice. I’m reading the books, and I’m so disappointed of what could have been for the origins of the Federation with Archer

All are good story arcs for Legacy to help wrap up. Do bare in mind, the show cant just be a loose end tie up show only, it needs it's own unique flare. Patching up things could be done across say Prodigy or lower decks. LIke for instance how we found out Nick Lacarno ended up with his atom's helping create a Genesis planet. Tom Paris remained in starfleet for example. spread the patch up across shows is all im saying. Although showing where other characters ended up on the show wouldn't be a bad thing. E.g. The Doctor - Arrives on the Enterprise with a full medical complement to assist in a plague on a Romulan Colony. Dr Crusher could Cameo because via sub space the Doctor who now has the rank of Captain reports back to her. Naiomi Wildman - Now a officer in starfleet, perhaps Raffi has to take leave because of her grandchild or some other reason but Naomi (may be recast if Scarlett doesn't want to play her) arrives to assume the first officer position in Raffi's place. Perhaps requesting at Raffi's return to remain aboard the Enterprise and Seven saying "Ill make room for you". Colonel Kira - May be we could see her commissioning as a Starfleet Captain on Bajor's entery in to the federation. (another loose end there) Miles O'Brian - Perhaps he was offered a provisional commission of Captain or Commander and is on the path to running the 25th century Academy. He has found teaching for-filling. Molly O'Brian - Molly Could be a NCO in starfleet, following in her fathers foot steps. If not on screen, we perhaps have another character reference her who says she's Chief of Operations of Starbase 14 (using a random number). Liam Shaw - Revived by Q, Perhaps he is offered a position of authority at the new Utopia Planitia yards with rank of rear admiral or commodore but perhaps turns it down stating "I may no longer be the commanding officer of this ship but! A Captain does not abandon ship" this would be a nod to his time in the battle of Wolf 359. Seven would allow him to become "Captain of Engineering" aboard the Enterprise. Making him the second Character we know to hold the position. Perhaps Seven and Liam come to blow's often but she respects his engineering ability. In his own way he still respects her like he did at the end of Picard despite showing distaste for her. The respect could be shown when at different times, one is injured saving the other, showing they will put their lives on the line for each other. Perhaps Seven even say's "Its a unique relationship". May be he says something to Seven in front of say Admiral Janeway and she's about the jump in to Seven's defense but Seven says "Admiral, its okay". Perhaps the growth of the two's relationship becomes one of banter eventually, insulting each other as they get closer. Harry Kim - Perhaps Harry is Captain of the Rhode Island, this was always his fate. That's just a few characters but you get the idea.

2nd season of picard would have been the best opportunity to bring TASHA YAR back. The Confederation would have blasted Armus to kingdon come, Tasha Yar could still be alive, and she could have been worked into Episode 2 briefly as a "resistance leader."

If they do a story line with the Delta Quadrant they could tie that into learning about the Borgs’ origins.

Garek taking control of Cardasia, is like Nog being Grand Nagus, or Worf being informed in the highest ranks of Klingon governess. It makes the world seem smaller to have these characters in such high positions, and hinders world building

How about more exploration of the Tholians?

I really want to see a crossover of LD and Legacy... Maybe a LtCmdr Boimler?

Honestly would like to see them bring back Trelaine in a show, I know he has been used in books and comics but it would be interesting to see him return on screen and interact with the Enterprise G not realizing how much things have changed for mortals.

I agree with all ten. A mix of episodes that pick up on these loose ends with episodes featuring original stories would provide plenty of material for 50 episodes.

The Kurtzman era is weird, instead of starting with two obvious series, a Christopher Pike prequel (they got there in the end) and a post-Dominion War, post-Voyager continuation series, they went off on a bunch of non-essential tangents and then seem surprised when something does get traction that clearly hasn’t been planned for. I despair…. Let’s be real, what you are pitching is actually two different shows - Delta show with Seven and a Gamma show probably with Ezri Dax. Ezri Dax is the least developed of the major DS9 characters and the fact that she IS DS9 means that she is a far more natural fit for some of the ideas you suggest. A show focused on an older, wiser but still fundamentally kind and nurturing Dax who has tapped into her potential and fully integrated the various Dax personalities into her own and climbed the ladder either as a Starfleet officer or a Federation diplomat. Dax, former mentor to Sisko, ex-diplomat in her Curzon incarnation, ex-scientist as Jadzia and ex-Counsellor herself is the perfect person to take on the Sisko, Gamma Quadrant and Garak elements of your proposal, even if it is just as a run of say 3 or 4 Long Treks. She knows the Dominion, she knows Sisko and she actually counselled Garak, so talking him down or putting an alternate point of view to him isn’t out of the realms of plausibility, they already have the foundation of a pre-existing relationship to draw upon to tell that story. If they wanted to tap into the Ferengi again, a DS9 staple, then she’d be as a tongo champion via Jadzia would be a good way to do it. She has a pre-existing relationship with Kira and a Counsellor who has in Jadzia’s form actually met the Prophets is a good person to choose for a return to Bajor story and again, she has the relationship with Martok and Worf, Dax covers the Klingon elements too. Let’s say she’s some kind of Federation trouble-shooter: Long Trek #1 - tensions rise between a Bajor now a member of the Federation and a reviving Cardassia. Long Trek #2 - reviving Federation interests in the Gamma Quadrant and potential Dominion interference there. Long Trek #3 - an August 1991 anti-Gorbachev style coup against Martok as hardliners want to force a war with the Federation for not letting them scoop up all the loose Romulan territory and Worf and Dax tag-team to save the peace. It taps into Star Trek VI territory too and gives us a Klingon-focused story whilst we get to see Martok matured by his life as a politician trying not to destroy the Empire weakened by military overspending, under-development in other places and a whole lot of false or fake honour. I agree, the Delta Quadrant and Species 8472 belong naturally to any show focused on Captain Seven, complete with her different perspective and the obvious bigotry she’d almost certainly receive as someone who is visibly ex-Borg in a part of the Delta Quadrant thrown in the air by the actions of Voyager. Species 8472, the Caatati - the species we met in ‘Day of Honor’ who demanded she be handed over to them to take revenge upon in-exchange for Voyager’s warp core, the Brunali, there are a few. Getting people to trust her despite her history would be half the battle and overcoming the fact that Voyager is the “ship of death” meaning the Federation likely has a bad reputation in the Delta Quadrant which might challenge some of the other, younger characters in their assumptions. Going to the far edges of reachable space with current for then technology would actually live up to the Enterprise name and provides a good opportunity to build upon what’s already there without adding too many elements that cannot be properly explored in the 10 episode structure we are going to get. I’d also argue they REALLY need to resolve some threads from ST:Picard, starting with the Romulans and that could be a good arc right there. The Enterprise on a major mission combining diplomacy, security support and humanitarian assistance in the former Neutral Zone and then ending up in a bigger quest provides the perfect opportunity to set the table on the tone and feel of Legacy whilst revisiting Sela and developing Seven’s back-story as a Ranger, along with some of the other characters - Raffi’s different approach to command and decision-making; Jack’s shoot first style; some of the younger crew like Sydney’s relative in-experience and give some space for them to be affected by the Borg experience they had recently. Explore a bit the contrast between Sela and Seven, both hybrids but nurtured in very different worlds. It writes itself.

What about the Mirror Universe? I'd like to know what happened after the Terran rebels captured Regent Worf in "The Emperor's New Cloak." Did the rebels ultimately win their freedom from the Klingon-Cardassian Alliance? Did the Alliance retaliate and liberate Regent Worf? Is Terok Nor still standing? Inquiring minds want to know!

What about the backup/copy of the Doctor, that decided to return to earth after centuries?

Yes...the Sisko must return. But, I think that an origin story about the planet killer from TOS: The Doomsday Machine would make a fascinating story for a Legacy story arc or one shot. It would be interesting to see how the Federation and its allies would deal with perhaps a far more complex and deadlier version of the planet killer.

That’s a respectable list. Also Unimatrix Zero! Don’t forget that Species 8472 could mimic humans with the use of genetic enhancements. 8472 also had a sorta connection to Sevens love life as her former interest Axom from Unimatrix Zero was revealed to be on a cube patrolling “near fluidic space” I believe. I especially support a show concept that sees Seven returning to the Delta quadrant as there’s a long list of stories & characters to revisit.

I’d love to see Joseph Sisko appear in Lower decks or legacy

It's not repetitive to keep mentioning Sela, it's consistent. You know what you (and the rest of us) want, and you're not afraid to say it. I approve. Now, where's L.E. Fontana? We were told she'd be back, and it's been over an hour.
