Warmonga

Warmonga is a giant female green-skinned alien from the planet Lorwardia. She's a warrior woman standing somewhere around eight to ten-feet tall.

She journeyed to Earth shortly before the episode "Mad Dogs and Aliens" and broke Dr. Drakken out of prison after an intercepted broadcast of his earlier performance on ''American Starmaker. T''his broadcast lead her to believe that Drakken was "The Great Blue One": a legendary figure from her planet's mythology whom, it was prophesied, would lead her people to conquer the universe; a leader to whom she would pledge her allegiance and her arsenal of advanced weaponry. With no other point of reference to work from, she comes to this conclusion through the part of the prophecy that stated the Great Blue would contact her people from "beyond the stars".

Excited at the prospect of being able to access advanced Lorwardian technology, Drakken agrees to join forces with Warmonga. The alien proves too much for either Kim or Shego to handle alone; however, working together, they manage to gain the upper hand.

She eventually leaves Earth after Wade and Jim & Tim fabricated a new "Great Blue One" out of their school mascot costume and convince her that Drakken is not the person that she has been looking for.

She reappears later on in the 2-part final episode "Graduation". She returned with her battlemate Warhok, commanding an invasion force to conquer the seemingly primitive Earth. Warmonga is finally defeated when Ron Stoppable manages to tap into his dormant Mystical Monkey Powers and defeat her and Warhok in single combat, throwing them headlong into their crashing spacecraft just before it explodes. She can be heard screaming "Frackle!". Her ultimate fate was never confirmed, though it is intimated that she and Warhok were killed.
