The Illimitable Tank (イリメタブルタンク Irimetaburu Tanku?) is a bomb-like Unversed appearing in Kingdom Hearts Birth by Sleep. They will continue to take damage in battle, and may glow red, eventually exploding as they roll around and bounce on the battlefield and increase in size, immune to damage at this point. This rotund Unversed's devastating explosion attack can only be avoided if one attacks it from behind.
