On the other side of the door was a severely mutated dragon. His large size, disproportionate body parts, and lumps all over his body suggested he'd been experimenting on himself. He went after Tony first, and seemed surprised that he was able to fight back. Tony's attacks didn't seem to be doing much, though.
"This one's tough, isn't he?" Ralph said. 
Normally, Ralph would just fly out of his reach, but the ceiling was too low for him to do that this time around. He tried to put as much distance between himself and the mutant as possible. He then shot fireballs across the room at him, hoping they would do more than Tony's attacks did.
