The last time I played the game for some reason Baku was always attacking him in the two boss fights. I think his boss hates him. Also his name and hat reminds me of the dude off the box of Cinnamon Toast Crunch. My favorite is of course Zidane since he's my favorite video game character period, but outside of him I'd give it to Marcus. Ruby was memorable because of her blue hair, southern accent, and zany personality, but the Nero brothers are only memorable for being the only non-humans in the group.
