I'm still not too sure yet, I usually choose either Loran or Usso. But I think I could see myself try Amuro (0079), Gato or Judau... or maybe Tobia or Graham... I'll probably choose when we'll have the skill list =3
Official "Bernie with a mustache throwing nuclear grenade" of the G Gene World board.
