I noticed someone else's post and realised that this would be the ideal place to ask if anyone remembers this game:
It was a robot fighting game for the PS1. You designed your robot from a limited number of parts and then went into battle in a 3D arena. If you won, you could choose one of your opponent's parts as a prize. The weapons that I always remember were a punching arm (the hand was simply a white ball) and grapple that you could shoot out to pull opponents in.
I've hunted secondhand game stores for years and never found it.
