Suggested by Sonic Mokujin is a powerful fighter who has mastered hand to hand combat. His rock type body also increases his durability but it’s not going to be enough against a mage like Orko. Orko has a whole bag of tricks up his sleeve with all kinds of magical blasts at the ready. Mokujin has no way to dodge and Orko is much more agile since he can fly. Orko wins.
