Satan let the transformation finish as Lust fired at him. Huge, scaly wings ripped out of his back and he grew very quickly in a very short span of time. Where someone who could have been mistaken for human had once stood, there was a dragon. The bullets pinged off his scales, though he was far from actually being bulletproof. Enough shots would hurt him, but he didn't plan to be hit.
Opening his mouth, he let out a jet of fire at the two Sins and darted forward as he did. With a swat of his paw, he sent them flying out the glass doors. His own exit into the street smashed out most of the front wall, but he doubted Lucifer would care. At the sight of the other Sins, he breathed another wave of fire.
