Chitauri Gorillas

The Chitauri Gorillas are supporting antagonists in the 2019 Marvel film Avengers: Endgame. They are a group of alien gorillas that are subservient to the Chitauri and serve the infamous Thanos and the Black Order.

Role
The Chitauri Gorillas were known for helping out Thanos and the Black Order in slaughter their enemies and wiping out half of civilizations' populaces due to their enormous super-strength.

Five years after Thanos' destruction of half of all life in 2018, the remaining Avengers and Guardians use the properties of the Quantum Realm to travel back to different points in time to collect the Infinity Stones and use them to undo Thanos' actions; however, due to the sensors of Nebula's past and future selves interfering, the 2014 Thanos ends up learning of the Avenger's plans and that they had killed him in their time. Enraged, Thanos decides to use the Stones to wipe out all life and create a new universe, and has 2014 Nebula impersonate her future counterpart and bring his ship and all of his forces, the Chitauri Gorillas included, to the future.

After bombing the Avenger's headquarters and defeating Thor, Iron Man and Captain America, Thanos unleashes the Gorillas and his other minions upon the earth to destroy the Avengers and ravage the planet. However, they are opposed by an army of the Avenger's revived allies, who fight with the Gorillas and the others as they try to get their hands of the Infinity Gauntlet. However, in the end, all of the Gorillas, along with Thanos' other forces and Thanos himself, are killed when Iron Man sacrifices himself in using the Infinity Gauntlet to destroy them all at once.
