Barbaric Machine Soldiers Ugatz

The Barbaric Machine Soldiers Ugatz are Gaiark's android grunts who fight the Go-Onger and pilot the Gaiark Mecha. When Nigorl arrives, he brings his own feminine Beauty Ugatz in Episode 26, which are stronger than the regular Ugatz.

In Gokaiger, an army of Ugatz are part of the Gaiark remnant led by Pollution President Babatcheed. A force of Ugatz led by Barbaric Officer Chirakashizky attack Gunman World where they are defeated by the Gokaigers, but as Babatcheed reveals to them, the attack was just a diversion so Babatcheed could close off Human World so that he could conquer it unopposed. However, Babatcheed was confronted by Zangyack, with a battle ensuing between the Ugatz and Gormin. With the help of Machalcon, the Gokaigers were able to return to Human World and, with the power of the Go-ongers, destroyed the Ugatz.

Combined Combatant
Several Ugatz were part of an army of past enemy grunts that were fought by the Gokaigers in Los Dark's ghost dimension which housed the 1500 spirits of the villains defeated by the Super Sentai. After losing some of their number in an initial skirmish, the remaining members from each grunt group merged to form the Combined Combatant. Though the stronger opponent, the Combined Combatant proved to be unstable due to internal conflicting among the grunts composing him over who got to finish the pirates off. Taking advantage, the Gokaigers used the Battle Fever J Ranger Keys to destroy the Combined Combatant with the Penta Force cannon.
