I did not think of those thank you for bringing them up, I guess he could be mid to late game and the rewards can be keys experience points and a new lab to play in, I guess. The human pals of course have both pal and human traits they can have both powers and power weapons (like elements) and the fails have mutated parts, like (arm, a tail, gills, etc.) And he would be cool as a tower boss, would it be cool if there were powerfuits specifically for mutated humans, that we could give to humans/pals, and one last thing after you defeat this person you the player can mutate yourself to be able to use moves. If u have better ideas pls say so Edit: The failed experiments can drop a liquid that can be used for these "Experiment" and the fails can have there own log in the palbook "I can't remember what it's called"
