Cyborg is one of the main characters of Teen Titans. He is the half-cybernetic half-man, chief technological expert and one of the five founding members of the Teen Titans.
Cyborg was a promising strong teenage athlete named Victor Stone, before an accident killed his mother and injured him so severely that his father replaced the damaged body parts with cybernetics to keep his son alive. But since these mechanical parts were not inconspicuous, he was shunned by his home environment and his friends, which frustrated him greatly. This caused him to have resentment and hatred for his father.
