An impish young boy with a genius-level intellect who is armed with a mechanized backpack that generates multiple devices, gadgets and weapons. Gizmo is also a well-versed computer hacker and inventor, and typically uses these skills against Cyborg in some way, exploiting his robotic weaknesses in any number of episodes, even when called upon by the Titans to help save Cyborg's life in the "Crash" episode. Gizmo was also a short-lived Honorary Titan following the events of "Winner Take All", but was quickly stripped of that distinction.
