No but you can get Lugia in Pokemon Xd just trade it to a GBA Pokemon version like Ruby then trade it to colosseum.
It evoles at Lv. 33 on Emerald, Sapphire, and Ruby. That's not true. you cannot obtain lugia in ruby or sapphire only emerald. And that requires a mystic ticket via event. Also lugia can't evolve or breed due to being a legendary. only manaphy can.
