Groot is a member of the Guardians of the Galaxy.
Groot is an sentient alien plant who spends most of his time within a pot of soil. He appears to have a limited vocabulary, but his team mates can understand him. He can grow into a giant humanoid tree like being with superhuman strength. He is a leading member of the Guardians of the Galaxy alongside Star-Lord, Drax the Destroyer, Rocket Raccoon and Gamora and Nova.
The Guardians battle the Chitauri an alien race led by Korvac. When Rocket Raccoon's ship is pulled into the Chitauri ship, Rocket fakes surrender so that they can free the captive Guardians of the Galaxy members. Afterwards, Spider-Man discovers that the Chitauri are planning to destroy the Earth. The Guardians plan to run the Chitauri ship into the sun while fighting the Chitauri forces. When their tactic does not work, the Guardians end up making their way towards the Dark Matter Cannon. While Nova and Spider-Man head to the Dark Matter Cannon, the Guardians fight the Chitauri and Korvac. After Korvac is defeated by Groot, Nova destroys the Dark Matter Cannon and the Chitauri ship is destroyed.
The Guardians of the Galaxy land on Earth to repair their ship at the time when Titus was leading the Chitauri into claiming Nova's Helmet. After the Guardians of the Galaxy's ship is repaired, they helped Nova and Spider-Man fight Titus and the Chitauri. After Titus was defeated even when S.H.I.E.L.D. arrives, the Guardians of the Galaxy leaves with Titus in their custody while the remaining Chitauri escapes.
