12.
I can't choose my top three in total, so I have my top three of each gender.
Male:
Mithos: Before that it was Lloyd, then Zelos, then Lloyd again. However, after watching Tales of Fandom 2 and seeing the flashback between the Four Seraphim, and then the other flashback with Mithos, Martel, and Kratos, I grew to appreciate and adore him much more. In general, I do like how it's just an actual bad guy, just extremely misunderstood, and had simply misunderstood what his sister meant.
Lloyd: I'm not... too sure, but I guess it's just that vibe that he gives. And he wears Red. Go fig.
Zelos: While he's a prevert on the surface, his background story lets me appreciate him more. That, and he's hilarious. <3 and he has red hair, go fig.
Then Genis would prolly have to be forth.
Females:
Raine: To be honest, I'm not too sure how she made it to the top of my list, but she's amazing. She pulls off being a teacher/sister/mom really well, even though she can't cook for her life.
Presea: She's small. She's cute, and a loli, and she's a strong one. From the moment I first met her I loved her. <3
Colette: I ... actually didn't like Colette too much when I first met her, because I didn't like people who say 'sorry' too much without much of a reason. But she grew on me. She definitely grew on me, and now I just find her simply adorable. :3
Fourth would have to be Martel.
