This is Ollie, my OC's introduction to dA. Here's a little bit about Ollie.
Name: Ollie
Age: 12 years old
Description: Ollie is an old abandoned doll, with his over-sized head drooping forward. He stands about 30cms tall, and lurches forward on stubby legs when he walks. His black button eyes stare blankly forward, a long stitch running through his left eye. A long, black pin protrudes from his head, glinting as it catches the light. His hairless "skin" is a rough, tan colour, and shifts awkwardly on him when he moves around. A long grey striped tail drags after him.
Past:Ollie was once a much loved cat doll, fluffy and soft, but he was abandoned for a newer toy. After many years of mistreatment, he has lost all his fur, leaving him a horrendous monstrosity. After finally escaping from the home where he was kept locked up in the attic, he now wanders the streets, in search of his beloved master. If he sees a child resembling his former master, he will run at them, arms outstretched, yelling something along the lines of "dO YoU waNt to PlAY? in a starched, cracking voice. The child at this point has two options. One is to take Ollie in, and take care of him, to show him the love that he was denied for so many years, but to put up with his endless torment. Although later on, Ollie will calm down, and return to the harmless, loveable toy he previously was. The child's second option is to run away, but Ollie will chase them, exhibiting super-human speed, until he catches up with them, and kills them.
Personality: Ollie shows signs of being a sociopath, traits like unable to show shame or guilt are evident in his actions. Although when shown love, he will return to being the tame, lifeless toy he was in the first place.
