The fearsome Titanisaur belonged to Captain Mutiny. He was used as means to transport Mutiny's Castle and Mutiny himself from place to pace over long distances, as the beast could swim underwater and fly through space. In battle he can fire energy blasts from his mouth, use his tail as a weapon and has jaws that can rip a Megazord's arm off.
However, Titanisaur doesn't do anything in the series until the episode "Raise The Titanisaur", where Captain Mutiny uses him to attack Terra Venture. The Galaxy Megazord, Stratoforce Megazord and Centaurus Megazord attempt to fight Titanisaur, but he defeats them all easily. Before he can leave to attack the city, however, he starts to overheat, so Captain Mutiny retreats back to the sea where the water cools Titanisaur down.
To avoid him overheating again, Mutiny sends Titanisaur out without his castle attached to it. The rangers confront Titanisaur again when he's attacking the city, initially fighting him with the individual Galaticabeasts, with little success until Titanisaur is struck by the Lion Galactabeast's fire power. The Rangers then form the Megazords, and prove far more successful, with Titanisaur's tail being cut off by the Defender Torozord's axe, and Stratoforce and Centaurus injuring Titanisaur with their combined attack, before the Galaxy Megazord finished him with its powered up saber.
