Captain Chantel DuBois is the main antagonist of Madagascar 3: Europe's Most Wanted. She is the head of the European Animal Control who desires animals heads for trophies.

Madagascar 3: Europe's Most Wanted
DuBois first appeared near the beginning being called by hotel security about the animals Alex, Marty, Melman, and Gloria. She pursues them in order to catch the animals, mainly Alex, to mount their heads on the wall as trophies. She sniffs for them in the same manner as a dog, and upon picking up Alex's scent, follows them in a long chase scene that ends when the animals try to escape on their plane. DuBois lassoes Melman's neck, only for the rope to be cut by Alex, and she falls into the pool. As they fly away, she resurfaces, saying, "Well played, lion. Game on."

She was later seen at the railroad that the animals were just at and uses her smell (and laps up some filthy water from one of Alex's footprints) to find out they have joined the circus heading for Rome and London and promptly jumps aboard the next train heading for the same place. She is briefly arrested in Rome but escapes by hiding in the bed while creating several other escape routes to trick the police. They jump down a hole they believe DuBois went down, and she cuts out from the bed, locks the police in the jail cell, and uses the computer to search up Alex and realizes he's a zoo lion from New York City.

She uses her singing voice to rouse her henchmen (who had been injured during the chase at the beginning) up and follows the animals once more, forcing them to retreat. She catches up to them with a paper of Alex, only to be catapulted away, though the circus animals see the paper and feel used and betrayed.

She finally captured Alex and the other animals at New York City, and the zoo staff thank her, incorrectly believing that she tried to return Alex. Alex is caged and DuBois hides a poison filled dart in a foam finger and shoots it at him, but the circus animals, being alerted by King Julien, arrive and rescue him. As revenge, she tries to kill Stefano, but Alex and Gia perform 'Trapeze Americano' to save him. After a long fight between the animals and DuBois and her henchmen, DuBois is tranquilized by Mort and her men are knocked out. She is last seen trapped in a crate by the penguins, being shipped to Madagascar with her henchmen.
