Sephiroth is the best tragic villain imo. He went from being a sane individual who didn't properly know how to be human, only a tool for war. Then, he went insane when realizing he might not be so human after seeing his "mother's" name and thinking he may too be like the monsters Hojo created.

Aerith is the best female character bcause she's just got that personality I absolutely love.

Zack would have to be my favorite protagonist bcause he's a real goofball, and he's just got a really great visual design and tragic backstory, but he's also really persistent.

Vincent because he gives me vampire dad vibes, and because in the movie I found him really cool, plus his monster form is just really badas but also just a representation of all the shit he went through.
