|Anything that can sink is worth sinking.|
The terror of the deep. If he's not stealing sunken treasure or ancient artifacts, he amuses himself by smashing holes in submarines and cruise ships. Electrically-charged, razor-tipped harpoon gun momentarily short-circuits on contact. Also armed with vice-like tentacles that stick to any surface. So strong underwater that he can wrestle a whale to a standstill. Inner robot convers to metal-rending crab creature equipped with depth gauges, deep-sea radar and acetylene torch gun.
