@Striker, Ise's original body is that of a normal human only. Without the Evil Piece, he has no Demonic Power, without the Boosted Gear, he has no Dragon aura nor the ability to double his powers. Remember Ise's Dragon power originally came from the Boosted Gear/Ddraig, just like Vali and Siegfried, without their Sacred Gears, neither of them would have any Dragon traits.
