Armin has a deep interest for the outside world, and is very analytical. He is loyal to the bone, and can keep a level head in and out of the battlefield. He has good ideas and can think outside the box, making him a force on the warfront even though he isn't very athletic. Armin is the current possessor of the colossal titan, but laments on how destructive his powers are. He can be manipulative if need be, and is convincing while doing it. He's empathetic, even to his enemies.
