Exterminate: Penetrator - it's a tough call, and Penetrator looked like it may have been reasonable in the arena with pretty tough armour for the time, but it was very slow, really lacked pushing power, and had fairly feeble weaponry. Plus it got outperformed on every stage by Wheelosaurus, which is saying something. Plus (admittedly a more minor thing), Wheelosaurus had character in bags and had that memorable moment where it beat up Sgt. Bash. I had forgotten Penetrator even existed.

Keep: Wheelosaurus.
