Christopher's attention snapped to the new entry in the room, stinger at the ready to impale in case kt was a hostile threat. It wasn't. Instead, it was a somewhat familiar face; a patient Christopher had seen a few times during periodic recess sessions. He remembered him as a rather small kid, and a fat one too. Now though, he was different having undergone changes of similar origin to his own. Rhys was taller, and definitely more muscular than before.
New senses kicked in as Christopher tried to place Rhys' specific "blood donor". Reptile... not Godzilla, but definitely a saurian creature. Gorosaurus. A foreign instinct acted up within him. Christopher needed to kill him, assert himself as a superior creature. More flashes of battles with other monsters went through Christopher's mind, but he resisted. He wasn't going to kill this guy for no reason other than "proving" himself as a better creature. He was different with the blood of Megaguirus, but he was still human in a way

"Hm... looks like you got a bit of a makeover like I did, eh? Good. About time those sickening transfusions did something good for us!"
