Hard cheese is a middleweight robot that has appeared in the early middleweight competitions.

Hard cheese has a spinning disc on its back in extreme 1, a pickaxe in series 3 and in series 2 it had spikes sitcking out of its back, although it preferred to drive into robots forward rather than backwards where they would hit the spikes. It is a wedge shaped robot with a fake rat on top of it.

In series 2, it won the middleweight championship. In series 3, it was knocked out-Sir Killalot helped out with that(in the extreme 1 battle, Jonathon even mentioned that he'd seen Hard Cheese before and that Killalot didn't like it). It lost along with five others in the extreme 1 championship.
