Terra, Sabin, and uhhh Red XIII are probably up there as some of my favorite ff characters. FF6 in general is one of my favorite games and I like most of the characters in that game, but during gameplay Sabin was consistently one of the most reliable characters and i dunno Terra just has a really fun character arc. Red XIII is good solely because being able to play as a cat is an extremely novel concept and for some reason I find him kind of funny. Ironically though I find Cait Sith absolutely wretched
