In Roy's setting, he could transmit any form of power to the Sky Dragon of Osiris and then have it amplify it, which naturally included his Transfiguration Beam.
Roy had always used the Transfiguration Beam as one of his trump cards because he could force even enemies stronger than him to transform for a second.
In intense battles, he could do too many things in a second.
Almost at the moment when the Transfiguration Beam burst out from Rafaro, Roy flashed. The moment Isabel turned into chocolate, Roy came to her side and grabbed this enormous piece of chocolate.
Then with a burst of strength, Roy directly broke the parts of the chocolate formed from Isabel's light wings!
