So, to change topic a bit, I just found this template online about most wanted fighters to each big third party (not sure why Platinum is there tho because they don't really have any ip to them but wathever). It would be fun if other use share it (or if you don't want to to the montage just reply through text).
Platinum is there because the specific companies mentioned are ones that have characters in the game, and presumably, whoever made this was either unaware that Sega owned Bayonetta, or they just included Platinum because they make a lot of great games.
As for the list...
-Konami: I'm assuming that assist trophies (Bomberman, Alucard) don't qualify, so I'll go with Raiden - we need Metal Gear Rising music!
-Sega: I'm torn between Eggman and Kazuma Kiryu, so I'll split the difference - Kazuma Kiryu riding in the Eggmobile! (just kidding; if I was forced to pick one, I'm going with Eggman)
-Capcom: Dante
-Bandai-Namco: Agumon (it was Heihachi, but the Mii costume seems like a consolation prize)
-Square-Enix: Geno
-Platinum: 2B (if licensed games were allowed, I'd at least consider Optimus Prime or Korra)
-Microsoft: Conker (Master Chief would make more sense, but I'd be more interested to see what they could do with Conker)
-SNK: Geese Howard
-Most wanted highly requested character: not counting any of the above, Doomguy
-Most wanted unlikely character: not counting any of the above, Miriam from Bloodstained
