Gizmo

"AHH! Robin...you aren't wearing any pants."

- -Gizmo, Laundry Day

Gizmo  is one of the main antagonists of Teen Titans Go!. He is a member and the team leader of the H.I.V.E. Five. Gizmo made his debut in the episode Laundry Day.

Bio
Gizmo first appears in the episode Laundry Day, where he made a robot army to take over Jump City, but soon retreated when he saw Robin naked and flew away with his robot army. In Super Robin, Gizmo appeared with the H.I.V.E. Five. He was easily defeated by Cyborg by a single missile. Gizmo joined the H.I.V.E. on their many missions to attack the city, mostly by robbing banks. He was a star player on the H.I.V.E. Fivers dodge ball team in Artful Dodgers. Gizmo is known to occasionally strike out on his own.

In The Left Leg, he attempted to conquer Jump City with his giant robot army from Laundry Day. He is also Cyborg's most hated enemies, after Brother Blood.

In Power Moves, he is seen destroying the city with his team, and uses missiles to destroy buildings. However, he later gets injured by a Power Move explosion.

He is Robin's rival, as they are both leaders of their respective teams.

Appearance
Gizmo is a little shorter than the average five year old, standing at three feet and two inches, and weighs a bit above average at fifty-five pounds. He is bald, but grey stubble from his buzzed hair is shown in some episodes. His eyes are white and have no pupils. He also wears green goggles and a silver backpack containing all of his gadgets inside. His entire costume is a dark-green one-piece suit with built in shoes.

Powers and Abilities

 * Inventing: Gizmo is a technological genius capable of creating ultra high-tech devices.
 * Hacking: His knowledge of computers and incredible hacking skills makes him a formidable foe for the Titans.
 * Flying: Gizmo can fly with his jet-pack.

Personality
In the original series, Gizmo is seen as a snobbish, immature young boy who is short-tempered. However, in Teen Titans Go!, he hardly calls anyone, even his friends or the Teen Titans, names, in comparison to his personality in the original series. His nasty side is only shown on occasions, such as in Go Fish! or Opposites, where he bit Robin for laughing when called five years old.

Cyborg
Gizmo and Cyborg are natural enemies and don't manage to get along well, despite having some similar roles. Cyborg hates Gizmo the most out of all the H.I.V.E. In Operation Tin Man, Gizmo kidnaps Cyborg, who doesn't seem upset at all due to being with Jinx. Gizmo argues with Jinx to not have her boyfriend in the H.I.V.E. Tower. This angers Jinx, who walks away, wanting them to make up. They instead cause a prank war, when Jinx finds out, she sends both Gizmo and Cyborg to Gizmo's room. They use an invention that could kill the Titans, but mess with them instead. When they go back, they become best friends, but they get seperated by the Titans.

Jinx
Jinx is Gizmo's second-in-command in the H.I.V.E., and the two are very close friends. She is the only member of the H.I.V.E. who is able to influence his decisions.

In Opposites, Gizmo becomes suspicious of Jinx's secret activities, and eventually discovers she's dating Cyborg. He immediately forbids Jinx from seeing Cyborg, but comes home to the predicament of Jinx endlessly balling her eyes out. After being overcome by her tears, he gives in to her requests, allowing her to date Cyborg and promising to becomes heroes.

In In and Out, Gizmo and Jinx continuously discuss the problem of the new H.I.V.E. members (the Titans in disguise). Eventually they resort to getting rid of them, because Gizmo believes asking them to leave is rude, which Gizmo has an idea to blow up the tower, which Jinx thinks is a dumb idea, considering they spent a long time building it.

Robin
Being the respective leaders of each of their teams, the two have a rivalry with each other. Gizmo and Robin are usually opponents whenever their teams fight each other.

In Opposites, as Jinx and Cyborg argue over their relationship, they both make insults about each other's leaders. Gizmo and Robin stand by each other, and have reasonable reactions, with Gizmo biting him, and Robin laughing. In In and Out, Robin decides to infiltrate and explode the H.I.V.E. Tower. As this happens, Gizmo is completely oblivious to his disguise.

In Yearbook Madness, Robin's hatred for Gizmo is shown where his imaginary yearbook has a photo of him slamming a locker on Gizmo.
