The Mecha Tyranitar is a large, robot that Tyrant normally controlls. It has many attacks that it is armed with, such as missiles, water powers, fire powers, ice powers, lightning powers and even 4 more seats! It has a large megaphone in the mouth, so Tyranitar can communicate out of it. It is the size of Groudonzilla, which appears to be the Mech's rival.
Karo found steel and iron pieces while he was an Aron, gathering them from caves and rocks. Tyranitar questioned why it looks exactly like him, Karo always avoids the conversation.
