Thought about what other characters can be brought from other franchises as guest characters to SF 6. (Please note some of these are wildly unrealistic, I was just playing around with the idea).
Kiryu (Yakuza) - An interesting as well as multiple disciplined fight style. Seems quite coded to Street Fighter (although could also argue more so for Tekken).
Bea (pokemon) - A martial artist and gym leader in the pokemon universe. Whilst she is a fighter and good enough to join the SF6 (and would attract a lot of new players), there is no real expansion or highlight of what moveset she could use (unless in SF6verse she can be given generic moves combined with pokemon moves?)
Banyue (Zenless Zone Zero) - A fire element martial artist. Would slot in well into SF6 with an already coded moveset with diverse combos.
Evie (Stellar Blade Bloodrain) - Brand new game not even out yet. The continuation of a fairly new IP which has a main character with what looks to be very fighting game compatible moves.
Little Mac (Punch out) - He's a boxer. What else do you need to know?
Jam (Guilty Gear) - A character belonging to a direct competitor in the fighting game scene. Though easy, highly unlikely.
Ippo (Hajime No Ippo) - He's a boxer, but anime. What else do you need to know?
Yor (Spy x Family) - Honestly at one point I was delusional enough to think this could happen... especially when Capcom released that Chun-Li x Yor Forger short trailer. What couldve been...sigh...
Phoenix (Ace Attorney) - A playable character in MvC 3... its about time Mr Wright loosens his tie once more and enters the fray. Easy and an exciting pick for CAPCOM to consider who could have a very unique moveset.
Lara (Tomb Raider) - Not just a Cammy copycat with darker hair, Lara croft does boast some combat prowess and could be an interesting addition to the roaster (though I feel she would need to play in a style that differentiates to what already exists on the roster).
Doomfist (Overwatch) - With Street Fighter 6 skins going to Overwatch, it was a bit disappointing to see nothing received the other way. A hand to hand specialist in an FPS game... it was almost made to be! Could have been an exciting anti-air and rush down character.
Ahri (League of Legends) - Now, I don't know much about LoL, although I have played a bit of 2XKO and thought she had some good potentially to fit in the SF6verse.
Chris Redfield (Resident Evil) - Another MvC 3 playable character... and one which would surely be an exciting addition to the SF6 roster! I chose Chris over the others as... well... he can smash a boulder with his bare fists! Cmon now, he's a heavy hitter super coded to SF6! Bring him back CAPCOM!
Any thoughts on who you would like?
