Can a water Pokemon beat a psychic Pokemon?

Answer 1

potentially, yes.

For instance, Gyarados can learn Dark Pulse (Dark moves are super effective on psychic Pokemon) and Gyarados is a Water type.

Also, neither Pokemon will really be super effective on the other (if they only have water and psychic moves, respectively, and are not of two types), so the stronger, better trained Pokemon will probably win, or they will each have an equal chance.

Answer 2

Yes it can, but it will appear not as effective as hitting the psychic type with a bug, dark, or ghost type. Try teaching your water type pokemon one of those move types.

Answer 3

A water and psychic type pokemon such as Slowbro will be weak against the following types: Electric, Grass, Dark, Bug, and Ghost.

Answer 4

Pyschic type beats pyschic type.

Answer 5

dark,ghost,etc
