Epsilon

A photon-powered advanced robot who dislikes fighting and cares for homeless children.

Created for war along with the other advanced ones, but refused to go there because of his pacifistic beliefs.

Arguably the strongest out of the war series, Epsilon uses the Sun itself as his power source, capable of launching various heat and light based attacks, as well as creating photon-shields and manipulating photons. Epsilon is also capable of willingly detaching his own hands and controlling them remotely.
