Hornitor

Hornitor was a large, silvery bipedal robot designed to resemble a hornet, Hornitor was one of Ivan Ooze's two Ectomorphicon Titans. Apparently the more powerful of the two between itself and Scorpitron, Hornitor lasted the longest against the Power Rangers and their Ninja Zords. Ivan then merged with Hornitor, making it grow bigger (apparently the metal was somehow maleable). Hornitor-Ivan was shortly thereafter destroyed when he/it was hit by Ryan's Comet in space while fighting the Ninja MegaZord.
