You have to breed it with a Pokemon that knows hydro pump like a male gyarados or lanturn with a female sharpedo. When the egg hatches I think you will have a carvahna with hydro pump.
Gyarados should learn Bite once Magikarp evolves at lv 20. Gyarados will then learn Dragon Rage at 25, Leer at 32, Hydro Pump at 41, and Hyper Beam at 52. Gyarados will also learn moves if you teach it TMs and HMs.
Gyarados cannot learn the move Hydro Cannon. Hydro Cannon is a move that can only be learned by the Water type Starter Pokemon.
You have to breed a female bagon with a gyarados that knows the move hydro pump.
As soon as its a Gyrados you can teach it Surf to start it off later it will learn Hydro pump.
