Cyborg's common origin story is that he was used as an experiment but was almost killed in an accident. How and what the accident was varies but the result is the same. He was outfitted with robotic modifications to save his life. Now he is looked at fearfully when in public and is something he always has to suffer with. He later joined the Teen Titans and they are his closest friends and there he met people he can relate to who have the same affliction in public that he does.
