Dragon Quest VIII Codebreaker Fun - 3 Rhapthornes VS The Monster Arena

This would be a great custom monster match code, except that the monsters that aren't meant to be in the monster arena have no stats at all. Can someone figure out a code that can give Rhapthorne stats in a monster team? Because even as of 2015, I can't change the god damn stats no matter what I try with cheat engine. Whatever it is, it's clearly beyond my skills. The code must be for codebreaker.
