It is considered to be the weakest Pokémon because it can only use three moves. It is a hardy Pokémon that can thrive in any body of water, no matter if the water is freshwater or saltwater. It can even thrive in polluted waters. However, if it is taken care of properly, it evolves into a magnificent Gyarados, at level 20. Until it reaches level 20, it is utterly useless.
