- Balthazar Bratt to his sidekick Fritz Balthazar Bratt is the main antagonist of ''Despicable Me 3. ''He is a former child star turned supervillain and the arch-enemy of Felonious Gru.

Past
During his youth, Balthazar Bratt played a character called Evil Bratt in his own self titled series, which revolved around him performing various evil deeds (such as robbing banks, defeating armies, destroying cities, etc). Although the series was beloved worldwide, during the seventh season, Bratt hit puberty and the series fell from popularity soon after. Bratt, having his reputation and career destroyed by his fall from grace, immediately turned to a life of crime, believing himself to actually be Evil Bratt.

Feud With Gru and the AVL
Balthazar Bratt quickly rose to the top of the Anti Villain League's most wanted criminal list and fought with them on various occasions, particularly with Felonious Gru, an ex-supervillan and the AVL's newest member as well as his partner/wife Lucy Wilde.

Attempting to Steal the World's Largest Diamond
Bratt, along with his robotic sidekick Fritz (who was also in the television series), robs a ocean liner transporting the World's Largest Diamond, using his rapidly inflating bubblegum to turn the ship airborne. Balthazar then gets into a fight with Gru, and, after disarming each other, begin "dance fighting", although Gru seemingly knocks him out. As Gru prepares to turn the diamond back to the authorities, Balthazar gets back up, stating that he was only pretending to be knocked out, and blows Gru away using a sonic keyboard, publicly humiliating him in the process. Before Balthazar can get away, numerous AVL agents swarm the liner, forcing him to escape. As punishment for failing to capture Balthazar, both Gru and Lucy are fired from the AVL by the new director Valerie Da Vinci.

Retaking the Diamond and Plotting his Revenge
After escaping Gru, Balthazar poses as the Constable of Paris and steals the real World's Largest Diamond from a museum in Paris. The next day, Balthazar Bratt's diamond heist makes the first page of the news, infuriating Gru. Later, Balthazar watches an episode of his television series in which Evil Bratt attacks a city with a giant robot and uses his expending bubblegum to float the city into space, with Bratt planning on doing the same thing to Hollywood as revenge for them cancelling Evil Bratt.

Against Gru and Dru
In order to get his old job back, Gru plots to steal the World's Largest Diamond back from Balthazar with the help of his twin brother Dru (who believes them to be stealing it as an act of villainy, not heroism). After making it to Balthazar's bedroom, they narrowly avoid waking him up and alerting him before he wakes up himself and continues working on his giant robot. After Dru accidentally alerts Balthazar to their presence by nearly choking on his expanding bubblegum, Gru throws the gum at Balthazar, sticking him to the wall while they take the diamond and narrowly escape his fortress.

Attacking Hollywood and Defeat
Despite having the diamond stolen from him, Balthazar improvises by disguising himself as Lucy, taking the diamond back and kidnapping Margo, Edith and Agnes. Bratt then initiates his plan and attacks Hollywood with his giant robot, shooting his expanding gum all over the city before placing Gru's daughters on the ledge of a building in order to give them a perfect view of the destruction he is causing. After shooting enough of the gum, Bratt uses the diamond powered laser cannon to begin separating Hollywood from the ground in order to let it drift off, although he is intercepted by Gru, Dru and Lucy, with Dru realizing his plan due to having watched Evil Bratt. Gru and Dru shoot Bratt's robot with a number of missiles, however, they prove to be ineffective and Bratt has his Bratt-Bots (modified Evil Bratt dolls) bring down Gru and Dru's plane. As Gru lays on the ground unconscious, Bratt begins firing his laser towards him, although, before Gru is destroyed, Dru destroys the robot's power core, causing it to explode.

Whilst trying to search the wreckage for his brother, Gru comes face to face with Balthazar, and before he can use his keytar to blow him away, Gru initiates another dance fight. After a brief fight, Gru snatches Balthazar's keytar and uses it to both blow him away and humiliate him in a similar fashion to how Bratt had previously done to him, leaving Bratt floating in his own gum. Bratt's fate is uncertain, although t can be assumed that he was arrested by the AVL, as both Gru and Lucy manage to get their jobs back.

Trivia

 * Balthazar's plan to float Hollywood into space is very similar to Ultron's plan in Avengers: Age of Ultron, however, while Balthazar only wanted to float the city away, Ultron wanted to crash Sokovia into the Earth and wipe out humanity.
