Magikarp may seem a stupid Pokemon to some but once they evolve into Gyarados, they can kick ass and do major damage.



But, I'm guessing that as Ariel's partner here, Vaporeon can do major damage to anyone wanting to harm her. I'm sure Ursula would get her own ass kicked by Vaporeon should she target it's mermaid partner/friend/sister if it's a part of her family.
