Hypothetically, how would you feel if Nick Brawl pulled an “Everyone Is Here”?

I recently found out that this game was apart of a series of Nick flash games and I wanna know how’d you react to everyone that’s ever been playable in these fighters (except Super Brawl Universe, that mobile game has TOO many characters) including bosses like Tiger Claw.

I’d personally enjoy it. I’m a sucker for “everyone is here” thanks to Smash Ultimate so I’d love to see all these guys come back. Sure there are a handful of characters from shows that weren’t well liked such as Breadwinners or Sky Whale’s Game Changers, but I’d love to see how they would put them in the game. But what do you guys think?

Also I may be going here after Multiversus’s shutdown. Again.
