Who do you guys might think we might see in a sequel? This game did well enough for one, right?
I think One Piece will probably add another crew member, like Zoro, Nami, Usopp, or Sanji since they're what I consider to be sort of the OC and have the most overall appeal. And probably another villain...Crocodile has the legacy, but at the moment Donflamingo is pretty much a major player so maybe him to represent some new blood. I honestly sort of want Akainu and Boa to be bumped to support though...
I hope Dragon Ball moves away from Saiyans, really don't want to see Gohan, Trunks, or Gotenks. Personally Piccolo would be my top choice, but I also think Mr. Satan as a joke character would be pretty amazing. I don't know if they'd consider using Beerus since his only manga appearance are the movie tie-in chapters, which I think was in a different magazine. Oh, and Kid Goku would be neat.
As for JoJo, I think they'll definitely add Jotaro, and probably DIO as well. I imagine they strayed away from the original as the anime production had yet to begin, but now that it's completed, I bet we'll see Stardust Crusaders stuff. I wouldn't be surprised if Kakyoin or Polnareff get in as well, at least as support characters.
I'd love to see YYH round out the cast by adding both Kurama and Kuwabara, but if I had to choose I might go with Kurama since no other character uses whips and plants to fight while Kuwabara isn't as versatile and unique.
Naruto, I think we might see Sakura to complete the main trio and for more girls, and probably either Kakashi or Rock Lee due to popularity. I also wonder if they'd ever consider using Bolt, or is he too new like Beerus?
Gintama will probably promote Kagura to playable, but I'd love to see Katsura, only for the fact you could probably incorporate Elizabeth running around with her signs as part of his move-set. Also have all his unique Cross-Talks have the other characters call him the wrong name.
Hisoka seems like the next obvious Hunter x Hunter representative, and it's a surprise he wasn't playable here honestly. I'm not that far into Hunter x Hunter so I don't know who'd be the next most likely character, but from where I watched up to Kurapika would be my choice.
From Otokojuku, make Edajima playable, and maybe J?
I hope they spin Don Patch off into his own character, maybe give BoBoBo Dengakuman instead and throw in the DenBo fusion...no BoBoBo fusions was a big disappointment for me. Heppokomaru would be pretty neat.
D. Gray Man is getting a new manga soon I read, so maybe Allen will be promoted to playable?
Kinnikuman is my most wanted New Series. In addition to Kinnikuman, probably Robin Mask or Ramenman.
Yugi would also be amazing, summoning monsters and everything. I'd also love to see Kaiba as well.
Yoh from Shaman King. Ultimate Stars I think had Anna as playable, as that'd be nice for more girls, but I'd love to see Ryu.
It's a pretty niche series, but I loved Muhyo and Roji, and would love to see them as a team-character.
Sena from Eyeshield 21, because I feel like football is a sport that doesn't seem as out of place in a fighter.
My Hero Academy has a lock I think unless its popularity dies...except I wonder how they'd do Deku's move-set, although I imagine he might be a more traditional fighter as the series progresses. The girl who controls gravity, forgot her name, would be a cool secondary character for more girls, but Bakugo and Todoroki will probably get in over her for having cooler, more battle-ready powers.
