You have to get Piplup for the starter Pokemon and level him up or trade for it.
if u want an empolion u must start a new game and get ur starter pokemon to be piplup and then evolve it to empolion or just use action replay to cheat it
empolion and have starly ,bidoof and pichu
i think so.
The only Pokemon that can learn Hydro Cannon are: Blastoise, Feraligatr, Marshtomp, and Empolion.
you must start with a piplup and lvl it up until it evolves into prinplup and then into empoolion

A penguin
She is not in Pokemon diamond.
There is no Pokemon temple! There is such thing as Pokemon diamond.
I think kingdra beycause dragon is the only that is super effective on him and his moves are good, Ludicolo, Kyogre and suicune. But Empolion, Blastoise and Lapras are also pretty good. NOT Gyarados I know he is cool and everything but electric moves are 4x effective beycause he is flying and a water type. Hope i helped :D
