The Ectomorphicon Titans were described by Zordon as "twin machines capable of enslaving the entire universe" (although this is debatable). The Titans were giant, ooze-powered silvery robotic death machines created by Ivan Ooze shortly before his imprisonment in the hyperlock chamber. The Ectomorphicons were then dismantled and buried nearby.
Six thousand years later, after Ivan was freed by Rita Repulsa and Lord Zedd, he used the zombified parents of Angel Grove to dig up reassemble the two robots, both of which were revealed to have a distinct insectoid flavor to them: Hornitor and Scorpitron. Both were destroyed by the Power Rangers using their Ninja Zords.
