?During your turn: Target 1 "Raidraptor" Xyz Monster you control; Special Summon from your Extra Deck, 1 "Raidraptor" monster that is 1 Rank higher than that target, by using that target as the Xyz Material.

?During your opponent's turn: Target 1 Xyz Monster your opponent controls with no Xyz Materials; take control of that Xyz Monster, then Special Summon from your Extra Deck, 1 "Raidraptor" monster that is 1 Rank higher than that monster, by using it as the Xyz Material.

(These Special Summons are treated as Xyz Summons. Attached Xyz Materials also become Xyz Materials on the Summoned monster.)
