Laughing, shifting, playing, changing, killing, smiling, morphing, rhyming.
Always speaking in rhymes and riddles, more often than not he'll just quote a nursery rhyme to communicate. Seems to keep quiet most of the time though. Creepy little fella. Seems a bit evil. Often makes reckless or risky decisions.
He can morph and change his form into anything of equal mass, such as bladed weapons and smashing tools, but not guns. He also carries a Magnum in the pocket of his hoodie, and a few clips of ammo. He cannot disconnect any amount of flesh from his body when he morphs, and cannot morph into anything with more mass than himself without absorbing extra flesh roughly equal to the size difference, which will have to be ejected from his body within two hours.
After crawling out of the unfortunate research facility he was accidentally created in, he traveled through the desert until he reached a small town in Nevada, which he then proceeded to destroy, that being all he knew how to do. When he was done though, he found a radio still playing children's nursery rhymes from a CD. He sat his then-formless body down and listened out of curiosity, then stayed and listened through 38 more repetitons until the battery ran out. Stumbling around the wreckage in search of similar prizes, he came across a picture of a child wearing a hoodie, and stared at it for a while before running off in search of a similiar garment. Eventually finding one stained a permanent nice, even gray by the ash of his destruction, he morphed into a humanoid form and put it on. Similar events lead to him finding his pants, sneakers, and gun.
Later that night, he turned the radio over and over, looking for the reason it had stopped working. He eventually popped open the battery case, and the two AA's fell out, one tumbling into a crevice between two pieces of concrete. He picked up the other and memorized it's form, tossing it away and going in search of more. Finding them, he replaced them using the outline guides on the battery slots as guides, then listened to the rhymes for another 48 hours straight. When it broke a second time, he smashed it, got up, and walked away, out of the town to wherever he heard something interesting.
