Kingdra does (not!) evolve! smart one! lol
train it to lvl 38 and trade it then pickaboo it will evolve into kingdra
Seadra can be evolved into Kingdra by using a water stone
Seadra can be evolved at any point in the game; to evolve it into a Kingdra, you must first get a Dragon Scale and give it to him/her. Then you must trade it and voila, your Kingdra.
to get kingdra you cant evolve it from seadra by gaining lvls, instead you have to make seadra hold a kings rock and trade the seadra to another pokemon game and it will evolve into kingdra
you get a horsea and evolve it twice.
Kingdra does not evolve further
you have to evolve horsie into sedra then evolve sedra into kingdra.
