Vector's Shark

​Vector's Shark is a large, adult great white shark (Carcharodon carcharias) that lives in a large aquarium of unknown size in Vector's fortress. Vector uses it as a pet and defense mechanism. It is dark greyish-blue on its back and white on its belly.

Despicable Me
The shark first appears in the floor when Vector is playing video games in his fortress. When Felonius Gru tries to break into Vector's fortress, it pops out of a manhole and devours him in one bite, although Gru somehow manages to survive and appears unharmed shortly afterward.

When Gru and his Minions are trying to steal back the shrink ray, the shark notices them and becomes aggressive. It tries to break out of its aquarium and attack them while Vector tries to get it to settle down, unaware that Gru is inside his lair. Later on, when Gru arrives to rescue Margo, Edith and Agnes and the fortress's entrance is destroyed, the shark jumps out of the water and opens its jaws, only for Gru to somehow easily knock it down with a punch to the snout, deterring the fish. Vector was stunned by this display and decided to retreat. It is also seen swimming in the background when the girls deliver the secret cookie robots to Vector.

Trivia

 * It is unknown what happened to the shark after Vector was stranded on the moon, though the possibility that Vector's father Mr. Perkins is currently caring for it does not seem all that outrageous.
 * Although it is unclear what the shark's gender is, it is implied to be male as Vector says, "Down, boy!" when it grows agitated.
 * The shark is shown to be very intelligent, recognizing Vector from other people and surprising Gru when it attacks him from a manhole.
 * Great white sharks are notorious for their tendency to die in captivity, as they swim long distances in the ocean and are very active hunters. Vector's ability to keep one alive and healthy in his home is truly impressive.
 * The shark roars like a lion when it bursts out of the hole and attacks Gru, and whimpers like a dog when it is punched by Gru.
