Teen Titans S02 E04 Only Human

"When there's trouble, you know who to call."

When Cyborg beats a robot named Atlas in an online video game, he challenges Cyborg to a real, physical fight; a fight Cyborg loses due to Atlas having lesser limits on his strength. Atlas then kidnaps Robin, Starfire, Raven, and Beast Boy as his prize and challenges Cyborg to a rematch where his friends’ lives are at stake.
