Street Fighter 2
(lock)
Mortal Kombat
(could go for MK2/3, but I dunno about going modern)
Super Smash Bros. Melee
(could go for Ultimate)
...
Soul Calibur 2
(this one's hardest but I'll give credit to it being an early success for 3D fighters, having three unique versions of the game, and having playable Link before Nintendo got Solid Snake and Sonic into SSBB)
Shout-outs to Eternal Champions and Dive Kick.
