Choobo is one of the Lieutenants of Lothor's forces and a recurring villain in the Power Ragers: Ninja Storm series. He is the teritary antagonist in Power Rangers Ninja Storm but the main antagonist of Return of Thunder four parter. He is portrayed by Bruce Hopkins. A plan he devised against the Rangers got him promoted to General, but after the plan failed, he was not only demoted, but exiled. Angry at the Rangers, he tried to destroy them on his own, but he was defeated. Choobo eventually returned to Lothor's army. He was last seen on the space fortress shortly before it self-destructed.
Choobo devised a plan to steal an ancient scroll that would give him powers and he could finally seek revenge. He was defeated by the Rangers and shrunken to the size of a doll where he was kept as a pet by Marah, one of Lothor's nieces. He was later turned back to regular size by Lothor on accident.
Defeat and death
In the final part of the two-part series finale episode "Storm Before the Calm", he was destroyed when Lothor's flagship self-destructed and during the rescue of Cam Watanabe by the Thunder Rangers. He was later released by the Abyss of Evil for the final battle. During the final battle between the Ninja Storm Rangers and Lothor's forces, Choobo was defeated by Shane as the Red Battlized Ranger, although it wasn't quite clear if he was completely destroyed as he was only seen falling down after getting blasted by the Battilizer's lasers.
