Flak was originally a low ranking soldier, but was promoted to his current rank by Hawke from private. Flak's helmet is based off German helmets and Max calls him an ape man. Flak's ability and CO powers focus on taking the chance to deal more damage, but at the risk of also dealing less damage than normal. This is called Dispersion. At first appearance, he resembles Jugger a lot, because they have the similar abilities, and their CO power and even their Super CO power are almost identical.
