Right alongside Titanium Rex comes his brother, Titanium Dax. So, in the show, Rex's people come from the center of the Earth, as opposed to space. Kind of a funny change considering they still treat it the same. Travelers from another world. I think Dax only showed up in one episode.

Hands were from a BossFight knight. Head was Mr Fantastic, with the mustache sculpted on. Sculpted the bracers, boots, belt, emblem, collar, and the shoulder pads. Full repaint, and all done!
