In pokemon white, you can catch Victini (limited offer that has already expired), Kyurem, Thundurus (runs first time, I suggest master ball), if someone gives you Tornadus, you can get Landorus in abundent shrine, Zekrom, Cobalion, Terrakion, and Virizion. Rumors say you can get these too, Reshiram, Zorua if you have a celebi, Zoroark if you have one of the kanto beasts (rumors say you can make eggs of the last two of them). You can also get a Volcarona and Larvesta if you want to consiter them legendary, but you can put them together in the day-care to make eggs.
