Lugia, Ho-oh, and Rayquaza for legendaries. Then for pseudo legendary Pokemon you have Dragonite and Salamence. Then for "normal" Pokemon Togekiss.
this is my opinion, but i think a togekiss is the best flying type. You can get it from an egg received by Cynthia in eterna city as a togepi. Evolve it until you find a shiny stone, (which you can find behind the stairs in the side exit of iron island) then use it on togetic, and there you have a togekiss.
Togekiss is a Generation 4 Pokemon, so it's impossible. (That and the Shiny Stone doesn't exist before that Generation.)
Togekiss.
