Imperious

Imperious is the second leading general of the Morlocks.

Referring to himself as the "Dark Wizard", Imperious sees magic as a way to grant his own selfish desires.

Imperious is a skilled fighter and extremely powerful, as well as supremely arrogant. He balances out his physical strength with magical powers, which are the same kind of magic as the Mystic Rangers' only to a higher degree, and can grow to a size more than one hundred times the size of the Titan Megazord, making him one of largest monsters in history. Imperious also has the ability to summon & free monsters from the Underworld.

He was formerly a friend of Udonna's named Calindor, a wizard who seems to be the same species of creature as the Mystic Titans. He could also take on human form. He was corrupted by dark magic and betrayed the other Mystics in the Great Battle, and when Daggeron found out the two fought a vicious battle. Upon being turned into a frog, Daggeron sealed himself, Jenji and the mummified Calindor within a cave.

Years later, Necrolai tricked the Rangers into breaking the seal and retrieved the mummified Calindor. Octomus brought him back to life as Imperious to serve as the new leader of the Underworld, a role Imperious took an immediate liking to.

Imperious briefly reassumed his previous identity as Calindor to gain Udonna and the other Rangers' trust, intending to poison Udonna, frame Daggeron as the traitor and steal the Xenotome. Luckily, Clare worked out his true nature and found out from Phineas he was the traitor just in time to stop Imperious from poisoning Udonna, and Daggeron prevented him gaining the Xenotome.

In his first encounter, he easily defeated the Rangers, and only Jenji's surprise attack and the fact his magic hadn't yet returned to full strength (due to being stuck in the cave) drove him back.
