Hope was definitely my favorite! =P
Lightning
Hope
Snow
Fang
Sazh
Vanille
Noel
Serah
Other (Monsters or NPC)
When I first played the game, I didn't really care that much about Snow, and adored Sazh and Vanille. Nowadays, with retrospect, Snow is my favourite and Sazh/Vanille come afterwards. Hope is my least favourite, idk about the rest but they're okay. Noel is a downer, though.
Bow before the mighty Javoo!
