Grunchor

Grunchor is Captain Mutiny 's frist giant Megazord-sized monster, who is a chunk skinned bottom feeder. He was a hideous monster used by Captain Mutiny to attack Terra Venture. Destroyed by the Orion Galaxy Megazord, Defender Torozord, Strataforce Megazord and Centaurus Megazord.

Sent as a Trojan Horse of sorts to Terra Venture and burrowed under their streets. Leo attacked him with a fire attack and he became bigger. As Torozord held the monster, the Megazord slashed with its saber, but the blow was useless against Grunchor. Mutiny's flying castle docked on Grunchor's head. Leo fired the Condor Missile Mode, but Grunchor swatted the blast back at the Megazord. Mutiny then deatched his castle. As the Rangers and three Megazords pooled their energies, the Orion Galaxy Megazord, projected a large stream of fire at Grunchor and the monster was roasted and dissolved into particles.

Note
In Gingaman, this is Titanisaur's second form after being revived by the energy of the Earth.
