Ivan Ooze

Ivan Ooze was a tyrant who was sealed away 6,000 years prior to the events in Mighty Morphin Power Rangers: The Movie. He appears as the main villain, summoned by, and ultimately betraying, Lord Zedd and Rita Repulsa.

Biography
According to Zordon, Ooze "ruled the world with a reign of unparalleled terror" until he was imprisoned in a Hyperlock Chamber by Zordon, Dulcea, and the "Order of Meridian", who presumably were the precursors to the modern Power Rangers. In addition to being a powerful villain of his own accord, he also had his own batch of enemy foot soldiers and zord-like constructs.

His hyperlock chamber unearthed by an Angel Grove construction crew. Zordon sent the Rangers to hide the chamber once more, but they were beaten to the scene by Rita and Zedd. Zedd released Ooze, and asked for Zordon's destruction in return. Ooze enthusiastically agreed, and breached the Command Center's security with ease. He demolished the Command Center, and destroyed Zordon's time warp, causing him to age rapidly. With the destruction of the Command Center, the Rangers lost their powers, forcing them to go on a quest for a new power source.

Ooze traveled to the moon, and once there easily deposed both Zedd and Rita, trapping them within a snowglobe. Their henchmen Goldar and Mordant swore allegiance to Ivan rather than join Rita and Zedd in captivity. Ivan then began brainwashing the citizens of Angel Grove into digging up his Ecto-Morphicons, large insect-like machines similar to the Rangers' Zords.

After the Rangers managed to restore their powers on Phados, they returned to Angel Grove and battled Ivan's machines with their new Ninja Zords. Using these Zords, they were able to destroy one of the Morphicons, Scorpitron. Ivan combined with the other Morphicon, Hornitor, and took on the Rangers himself. The battle progressed into outer space, and though Ivan consistently had the upper hand, he was destroyed when the Ninja Mega Falconzord kicked him in the groin and knocked him into the path of Ryan's Comet, which happened to be passing. The comet destroyed Ivan on impact. (Mighty Morphin Power Rangers: The Movie)
