YG, Jellyfish, and JYP lost a lot of talent right there

I've never had the opportunity to become a fan of a group before debut, and A.C.E is the first. You guys practice so hard and so much that you perform as if you debuted at least two years ago. All of you are so talented and I can't wait to watch you debut and anticipate your comebacks and just support you for a very long time ❤

Dance: Growl + Monster outfit: Call Me Baby

First of all God must have spent extra time on the five of them. Second of all I don't remember agreeing to stan such rudeness what even-

Is anyone else here after watching The Unit? Justice for Jun! He only got 2 lines in that performance and he barely got any screen time.... then my boi was last place in his group... look at his talent right here! Pls support the boys on The Unit.. (also the rest of the boys on MIXNINE)

Want them to be really popular like exo bigbang and bts but I am afraid somehow,because they will have lot of immature fans and I dont want that to happen.

Why are you all so perfect!? Your debut will be amazing~

ace dances in my favorite style - sharp, strong, and synchronized

Its so scary to see it so perfect x cant wait for them to release their own songs

Omg, loved this so so much. Petition for A.C.E to be the only ones to cover EXO. They’re amazing!!!

2:13 THEY DID THAT OMG

They really work hard for us and their debut and i really want to give them more succes but for me and Choice they don't need more success because we love them as like they are now

Usually in group band they’re only a few that are great dancers and the rest just keep up to blend in but here you can clearly tell that each one of them are awesome dancers 👏🏼👏🏼👏🏼

I'm exo-l and I know exo dances are not easy! But wow they are really pro and talented I think I'm going stan them

i love jason so much

I keep on rewatching this cover again because I think this kind of outfits suit them the most and of course their killer dance moves ... I really hope that somehow in their future comeback , they would have this kind of outfits as their main theme outfits together .. also I want Donghun to have this hairdo again ...he looks sooooo young and cute with this hairstyle ....

So proud of you guys, I love you A.C.E!

after all this time stanning A.C.E, i still can't choose a bias. they're all equally amazing

i love this group so much already and they are so amazing i can't wait for their debut

if they'll debut, if they'll be the guest in weekly idol, i'm pretty sure they'll slay in random dance

1:35 is so flawless, I can't get over it

I don't know why but I expect you all to know English ?? Do u ?? Loved. The. Dance. And. The outfits.

published on jan 11,2017,,i watched this on mar 14, 2018.I'm so behind the world.Why didn't I discover such godly dance cover earlier??IT'S FREAKING POWERFUL.They treat it like it's their own song and dancing for their own fans,,i mean they are dancing for their fans but wth...They're even hot like wts is this thing.I need moooore

A.C.E just oozes talent and superstardom!!! They excel in every way!!! And they are handsome and sexy as well!!! The total package!!! 💯❤️💙👑💜🧡💛

i forgot how good seyoon looked in red and black+ that hairstyle. truly a godsend. they all look really good though and they're all killing it with this choreo i'm actually screaming

i'm back after a year and a.c.e. is still so magical

아진짜 사랑해요♥

there isn't a single thing you guys can't do honestly omg ilysm

I NEED A FULL VERSION OF MONSTER!!!!

they look like nekoma volleyball club. esp the kenma fellow..... marvelous dancers though!

this is seriously better than the original version!!!

They fit concepts similar to Exo and Big Bang. I mean, they nailed all the covers so far.

홍대 버스킹부터 쫙 보고왔어요! 에이스 진짜 흥했으면 좋겠당!!!!

👏🏻👏🏻👏🏻well done guys 💖 EXO-L will always love you💖

엑소 커버하신분들중 가장 잘추시는거같아요ㅜㅜ 춤 너무 잘추세요!

Junhee is gonna cover Monster again on the Unit and I'm here because... the disrespect... 2:06

A.C.E is the first group for me to be able to follow before debut. I'm honestly so excited and already so proud of them they're so hard working and it's admirable. I seriously can't wait until they debut which I hope is soon! I will definitely support them for a very very long time!

oh man i love their exo covers so much u.u jun killing the beginning of monster and that part on the ground 2:15 thank u !! ps : is it just me or donghun's legs are much thiner than now and is the oposite for jun ( idk if is just me but i look at jun most of the time in dance practices lately donghun too) dont mind me im just too distracted by lots of stuff lately thanks to ace :D

Can't wait to see Jun dance Monster again! :D

キャップ被ってる人本当にかっこいい！！踊り方も特に顔の角度とか好き！！

They are great dancers hehe 😉🔥

OMG I need all the clothes, I think I've always liked men's clothes more 🤔🤔 my favorite dance cover 👏

When they debut I may actually explode. They're so talented that its kind of scary

sharp and clean moves

Flawless and amazing! I can't wait for your debut. You guys blow everyone away with your talent. ACE FIGHTING!!!!!

I've been busy with school so last time I was here they only had about 5,000 subscribers and now it's over 20,000 I'm super happy more people are finding about A.C.E they're amazing you guys won't regret stanning

I've been following many artists since pre debut days and I have to say that some of them really dissapointed me, so much that I'm always thinking twice before following pre debut groups in 2017..But it's like I can feel that A.C.E. simply can't dissapoint me. Only thing that I don't know is what concept will they have and how much will the company promote them. Those are the only things that could dissapoint me in this situation, but for now it seems like even that's not a problem! So, these boys better slay this year because they already took my heart.I'm rooting for them, they have high chances!

I'm so glad I found you all today, you're so talented! I'm stanning

You're all such amazing dancers 😘 Keep up the amazing work!

인간적으로넘하는거아님? 겁나섹시하잖앙ㅠㅠㅠㅠ흐잉

ACE, EXO, THREE DIFERENT LETTERS, EQUAL SUPERIOR TALENT
