I'm guessing this is for all the characters related to Tron...
1) Tron-I love this guy. He's epic. JUST EPIC. Everything about him. I might scare him though becuase I would fangirl all over the place if he was real.
2) Radia-I liked her from the instant I saw her in "Tron: Evolution". I'm a sucker for elegant characters. I was so sad when she was derezzed.
3) Bit-Me and my bro think Bit is totally badass. And he's cute.
4) Flynn-Obvious reasons.
5) MCP-Not becuase I take him seriously. (i can't.) But because he's win in a random way. Me and my bro are convinced he would be a epic troll. END OF LINE.
