Well, it's not absolutely necessary for anyone to come from a world like Rock's. I just thought that was a little common ground. XD;

I could maybe have him drop in to help with the Ultima Weapon thing at some point during the fighting. He's probably going to be running himself ragged at this rate. He's not used to being human after all. Humans tire more easily than robots do even when they're in good shape (and they're also less durable >_>). He's a big fan of war himself, but he's also used to stuff at least somewhat like this.
