I think it is Rotom. It can change it's forms to use Blizzard, Overheat, Leaf Storm, Hydro Pump and Air Slash. It also already has Lock-On, Thunder, Shock Wave, and Ominous Wind. Also, Rotom is NOT a Legendary Pokemon. You can capture one, trade it to your favourite Pokemon Game, repeat this process until you get 5 of them. Then change them to one of each form. I recommend HeartGold and SoulSilver, since you don't need any events to change Rotom.
