Kyo Kusanagi on any Tekinofaiter, not as cool or "Edgy" as Iori, but the man has a cool design, is easy to control but great to master and his themes tend to be the best sounding of any non boss character
Kind of vanilla, but i seriously rock Link in any Smash game, kind of heavy (In a game where falling is death, that's important) but if you know how to use him, he is pretty rounded
Princess Kurara in any Power Instinct she appears, not exactly competitive meta, but seriously, how many fighting games involving literal gangs has a Mahou Shoujo that can face a bunch of powered fighters that could fit in Tekken AND WIN!?
From Bloody Roar 2 and 3, Bakuryu, come on folks, what's not cool about a ninja that can turn into a mole? I also tend to play with Shina for... gameplay reasons
