No, Im pretty sure Penetrator lost in the tug-o-war through lack of traction. It was that rust-coloured box-shaped one (cant remember its name...Tanis or something like that?) that fitted a spike on the front for its battle with GBH that went out in the battles. And it couldnt have been a close fight, as IIRC both GBH fights were one-sided (flipping opponents quickly).
