Probably Smeargle.

Pokemon ruby, sapphire, and emerald. The legendaries are groudon kyogre and rayquaza.
I think it's just Rayquaza, not sure where though.
Rayquaza/Groudon/Kyogre each are level 70 and the only legendaries. And Latios/Latias
you should go look for the legendaries
Go Beat the elite four. And catch the legendaries like Kyogre and groudon. =]. -egyoshi
