"You sir are about to witness my full power." Rukia said.  Her wings grew leathery and 3 times as big.  Her claws grew into talons the size of Alageels body.  Her body grew scaly and became the size of a redwood tree.  She then let loose a roar and flew into the sky.  Her body covered the moon letting no light dow and shot a jet of flame as long and wide as the nile from her maw straight at Alageel.  It would be hard to tell her size in the darkness but one thing was known.  She was big.
