Cyborg believes that his robotic limbs have their limit in strength. He gets a chance to prove it when it falls to him to rescue the rest of the titans from an enemy robot.
Cyborg believes his mechanical parts have limits, which he cannot pass. The only way he feels he can improve himself is in a virtual game. When he is challenged by Atlas in the real world, he reaches his limits, and loses the battle. Atlas takes the Titans hostage. The only way for Cyborg to free his friends is to find a way to get past the limitations of his mechanical body.—Jesse Sanchez
