the problem would be with that is .... frieza was produced asexually from king cold

I feel like cooler being in some frieza prison, and frieza finds out or remembers him could be cool. He could have been training to escape, and we would get a what if frieza was trapped in the time chamber type scenario. I feel like this makes a better scenario than what if goku or vegeta was trapped, because the cast would jave to find a way to actually beat this guy. Concidering the strength of golu gohan and vegeta rn, this would be a good challenge.

What if Frieza and Cooler were both given their own empires and been sent to opposite ends of the universe to see who could conquer more as some sort of ego challenge rivalry? That's how you could explain Cooler's arrival and Frieza could be like "wtf are you doing here?" and Cooler could just make fun of him for getting bitched by "low class saiyans" multiple times and showing off how much more powerful he is than his brother. That's when it's revealed that Frieza's gold form ain't shit and Cooler already surpassed that ages ago cuz he actually cares about training (Super Cooler would be different from Z Cooler of course). Idk I just wanna see him come back and have a reason to be feared

I feel like a really easy way Cooler could've been canon was to just make him the Universe 6 frieza counterpart, instead of... Frost..

With a massive reworked backstory yes, it can happen because cooler was a dbz villain it would definitely work just because of that regardless of any impossibility we face

Remember Cooler and broly are the only DBZ movie characters who had a sequel movie. Cooler is also one of the few movies to not just have a connection to the destruction of planet vegeta, but actually uses scenes from the bardock special (which I believe broly did not). That and cooler is the same species as frieza, meaning we could get some lore about them for the first time. We literally have no name for them, no idea where they lived or even what a non-mutated version looked like; since king cold and frieza are said to be mutants of the species; not the normal version. Besides that the only thing we know is that king cold reproduces asexually which this idea can still work regardless as it never said there can't be a mom figure in their family. The animal kingdom in weird and even with them being able to reproduce themselves, they still group in families for survival. Like slugs; slugs are both male and female, so they can do both roles. Once a baby is born the often stay with them for a while before leaving. The only thing I wish they'd make canon along with Cooler is Lord Chilled; but not in the special version but a new version of them. Like a wise old sage or elder (which would make that floaty chair more like a wheelchair). This would give us someone who not only shows what happens when they get old, but also someone who can give knowledge that others might not have about their race. Maybe even the information about the saiyans that lead to frieza destroying them?

It would just be cool to have more frost demons and have more history on their race

I always imagined Frieza and Cooler were mutants of their race, that being their 3rd, 4th, and 5th forms were unique to ONLY them. This explains why no one else of their race would be relevant, and why King Cold looked like he was permanently in 2nd form. Maybe that's just the "mature" form their race takes after a certain age. The 3rd form, especially can just be a result of him preparing to transform into that 4th form while still IN 2nd form. Hell, his final body could've been birthed from that gigantic head, like a pod.

The problem is that Cooler is just a Frieza clone. He doesn't really have his own personality, he's just another Frieza when Frieza isn't around. Cooler would have to be an entirely new character with a different personality to be interesting - like Broly. Although Broly really didn't need it because he had plenty of personality in the original.

YESSIR!

Ah Cooler's your favourite too? And I wanna point out that King Cold birthed Frieza alone. He nor Cooler has no mother. I have my own idea for how to make Cooler cannon. Give him a spin off series. I have my own idea for one. Also, what's World Breaker Cooler?

I dont think king cold has a wife. arent they like namekians?

I dunno about this one chief...

The only way to make cooler can and it fits is to have him be an escaped galactic prisoner. Like he escaped when Moro broke everyone out and escaped to do his own thing to get his revenge on his brother for getting him caught in the first place.

Cooler's 5th form should have been black friezza's form. imagine how much more hype that moment in the manga would have been. also, imo ever since the TOP arc, Cooler has no way of being integrated ever especially in the way you did. he should be eitheir stronger/around namek friezza level or he should be from one of the deleted universes (have one of the kais or someone like them wishing on the super dragon balls for said universe to be brought back).

Yeaaaaah, no. This aint it dog.

Yeah no Cooler shouldn't be cannon. I mean you can spin it anyway you want but 1. Why is Cooler going Golden? Are we forgetting that Frieza alterd the coloration of his new form to match that of SSJ in order to mock goku and show his superiority. How would cooler (someone who's never met frieza face to face after his demise to the sayain or goku go golden) it would make more sense for him to have a different form. As for him going Black sure that kinda makes sense as that form is the peak of their races power. 2. Another reason he shouldn't be cannon is because it'll deminish the spotlight that frieza has, most of the dbz community doesn't care about cooler and would rather have that character slot in the story be taken up by someone else more deserving. Like idk Vegeta going to Universe 6 and meeting the King of Sadala. Someone who probably looks much like his father and we get a cool story arc of Vegeta helping the universe 6 sayains with a grand threat to their world as well as him training the other Sayains on how to transform. 3. Wouldn't Cooler have made a move against Goku and the Z fighters at this point, like where tf has he been. Im pretty sure he would have heard about his brothers death to a sayain which scattered the frieza force all across the galaxy. And if he decided not to show up to take out his vengeance on Goku for taking away the kill that was rightfully his then why doesn't he show up to help ressurect frieza in order to have their final showdown. Like theres too many plotholes of where Cooler has been in order to make him Cannon. It doesn't matter what story you craft it all just doesn't make sense for someone like cooler 🤷🏻‍♂️. Honestly think people just want him to be cannon because Broly became Cannon. Which was an obvious 1st choice out of all the non-cannon or sudo-cannon characters. Broly makes sense whereas all the others don't have a good story beat that lines up 🤷🏻‍♂️
