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 converts
to metal-rending crab creature equipped with depth gauges, deep-sea
radar and acetylene torch gun.
