Runs on a small antimatter core that rests in the waist near the pilot, because to be fair if it goes off anywhere on the mech the pilot is dead anyway. Vents along the side of the Wyrm allow it to vent excess heat, it's gun firing plasma projectiles. On it's back it holds twin boosters that allow it to make jumps onto higher surfaces. It's feet and arms are moddable, and can be equipped with suction cups and various tools, such as drill bits and more articulated hands.

Hell yeah bro, how else are the little chubby fűcks gonna defend themselves

Hjhj no too complex. This is just one I designed.
