He has Terraspin's body, which is covered in Upgrade’s semi-liquid body. His front flippers splits into three, forming clamps. The Mechamorph body morphs on his back, forming a catapult launch pad on top of his shell.
Powers and Abilities
Terragrade's main ability is shapeshifting, able to create technology on his back, in the form of a launch pad. He can form tiny arms to grab targets to put on the catapult, firing them at a target. His clamps help secure him in place. He can move the launch pad around to aim at his target.
Terragrade has enhanced computing skills, and can read the environment like a computer. He has been shown to measure the angle needed for fire, the wind speed, the velocity of the target's standard movements and likely path of movement.
Terragrade has to clamp down to use the catapult, making it immobile.
If it doesn't have anything to fire, it is virtually powerless.
