Ridley is a powerful space pirate who is both powerful and tactical. Momo in comparison is essentially an ordinary creature who does not have a whole lot of combat capabilities. I think the answer here is pretty clear. Ridley just needs to fire off a few fireballs and then use his speed to get Momo in a corner. With his options pretty limited as a result all Momo will be able to do is surrender. Ridley wins.
