While Kyo may be the "Ryu" of KoF, Terry's always been a more popular character overall from what I can tell. Should tell you something when SNK makes an official rule 63 version of Terry rather than Kyo so that way they can get one of their most recognizable characters into an "all female" fighter.

He’s also recently playable in a Street Basketball game.

I’m not joking.
