While Muddy is much like Tagg in many ways (To the point that he serves as his sidekick and is also a Soul of Silver), he also serves as a minor foil as he happens to be much calmer. However, his position as overall second in command has left him with some insecurities, particularly when most of his teammates capable of Mega Evolution managed to do so beforehand.
