Velociraptors JP3 / Alpha's Pack are the secondary antagonists in the 2001 film, Jurassic Park III.
Jurassic Park 3
Billy steals many of the raptors eggs, provoking an attack from the raptors. The male raptor, whom happened to be the alpha of the pack, tracked down and attacked Amanda and Billy and pinned them to the wall with the cage door. It then tried to climb up the cage door to attack them, but Amanda and Billy used this as an advantage to push the cage to the other side and trap the raptor, with the raptor calling for help. The alpha-female attacked and injured Udesky and used him as bait for the humans, nearly catching Amanda. When the trap fails, a male raptor kills Udesky.
They were chasing Alan Grant and Kirby family because Billy, whom accompanied them, stole their eggs and that led to their conflict and Udesky's death. Fortunately, both sides eventually make peace between each other after Alan returned their eggs.
Alan Grant is soon cornered on all sides by three male raptors and the alpha-female not long after the man eavesdropping conversation between Alpha and her mate. As they are closing in, Eric Kirby throws a gas grenade that drives the raptors away. Eric Kirby comes to save Alan Grant
They are not seen again until the end of the film, wanting their eggs back. The alpha-female comes to inspect the humans. She assumes Amanda stole them and sniffs her. Alan then gives Amanda the eggs, who puts them in front of the alpha-female. Alan then takes the resonating chamber Billy gave him and blows through it, distracting the raptors. Then Alan imitates their cry for help, resulting in one confused raptor charging at him, but is ordered by the alpha female to get back in rank. They then spared the humans, took their eggs and went away.

The pack's role in the game remained same with the film, but their characters changed into more family friendly: Here, while the raptor attacked Udesky, they're not killed him to use him as booby-trap. Instead, when some members of the pack chase main characters, the other crafted a complex trap composed of a phone as bait, hidden catapult and hanged cage. Udesky fell onto the trap and is put into the cell.
