What moves does Dratini learn?

dratini can learn moves like wing attack the coolest attack he has is when he is a dragonite then it learns hyper beam

in Pokemon heartgold/soulsilver, its possible to make dratini learn fly WITHOUT an action replay or hacking. just get a salamance that knows fly and a dragonite and breed them. if you are lucky, you will hatch a dratini that knows fly lol
