Anime: Jikuu Boukenki Zentrix

Famous scientist Jarad gives his OmicronPsy super-computer the power to spawn robots. Thanks to this, Jarad becomes Emperor of the world's most powerful city-Zentrix! But the OmicronPsy System computes that it has the power to override orders from its master. In an attempt to destroy the OmicronPsy System, Jarad becomes lost in time whilst transporting super-robot Zeus and himself back into the past.

Back in time, Zeus teams up with junior scientist Nick, Princess Megan and Mango the micro-saur, to fulfill the mission of destroying OmicronPsy and, in the course of their perilous journey to shut down OmicronPsy's Zentrium chips, a true spirit of friendship and loyalty develops between the quartet of adventurers. They need all the teamwork they can muster because they come under constant attack from weird and heavily-armed robots who know more about kung-fu-with-attitude than anybody.
