Thanatos
Thanatos is the end boss of Battle Clash (and perhaps of Metal Combat; I would like to hear about that). He is a powerful fighter, having defeated a thousand fighters (or so he claims).
Abilities:
Mech Piloting: Thanatos is a master of mech piloting.
Equipment:
Human ST: This humanoid battle robot is Thanatos' first form. It has charging forearm blasters, volleying chest energy blasters, and so on.
True ST: Thanatos' true form. This creature has several parts: side super energy blasters, auxillary attack "eyes", a main body, and dragon heads.
