hydro cannon
if you have empoleon go to route 228 you will see a old man he teaches hydro cannon but your empoleon has to really trust you.
Empoleon learns metal claw, drill peck, aqua jet, hydro pump, i think icebeam, and hydro cannon. best movesare drill peck, hydro pump, and hydro cannon(hydro cannon makes you recharge though)
Some one near stark moutain will give you a hydro cannon TM.
you have to have the move tutor teach it
Blastoise, Feraligatr, Swampert, Empoleon
Hydro Cannon
Gyarados cannot learn the move Hydro Cannon. Hydro Cannon is a move that can only be learned by the Water type Starter Pokemon.
go to a person near stark mountain
I only the best one for Empoleon that's hydro cannon
Why do you need a cheat code for Hydro Cannon????????????????????????????? If you have a Blastoise, Swampert, Feraligatr, or Empoleon you just have to bond with it and you can learn the move WITHOUT messing up your game with hacks.
