Ivan Ooze

Ivan Ooze was the main antagonist in The Power Rangers Movie. He is a tyrant 6,000 years ago, until he was imprisoned in a Hyperlock Chamber by Zordon and the "Order of Meridian", who presumably were the precursors to the modern Power Rangers. He also has his own batch of enemy foot soldiers.

His hyperlock chamber unearthed by an Angel Grove construction crew, Ivan Ooze was released by Lord Zedd after 6,000 years of imprisonment. Demolishing the Command Center and fatally injuring Zordon, Ivan destroyed the Power Rangers' powers.

He traveled to the moon, and once there easily deposed both Lord Zedd and Rita Repulsa, 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 gained the Great Power, 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 tossed him into the path of Ryan's Comet, which happened to be passing.

Trivia
While not canon, Ivan Ooze does have many Power Ranger firsts.
 * He is the first villain to have a sense of humor. This would be repeated by Lothor.
 * He is the first villain to fight the Rangers personally (Lord Zedd did not fight Tommy until half-way through season 3), and the first villain to fight a megazord himself.
 * He is the first villain to be able to physically possess one of his creations; the second was Venjix.
 * In addition to the previous statement, he is the only villain to be able to turn into a Megazord, or at least something close to one.
 * He is the first villain to be defeated by a kick to the groin into a comet. More accurately he is the first villain to be defeated by powers outside the Rangers (i.e. a comet)
 * Ivan is given the credit to be the first villain to overthrow Lord Zedd and Rita Repulsa. The second is King Mondo of the Machine Empire, although during both instances, the duo get back control somehow.
