Gen5 Landorus Thundurus Tornadus Reshiram Kyurem Zekrom WhiteKyurem BlackKyurem (I guess they count) Keldeo Genesect Coballion Virizion Terrakion Meloetta
Even if you take out the two Kyurem's, Gen 5 still had more legendaries. I wouldn't be surprised if people also counted the Therian and Incarnate forms as different legenedaries because of the stat changes >_>
Well at least in fairness story wise Kyurem, Zekrom and Reshiram are all supposed to be 1 pokemon but they got split up.
