PHASE 2 (may 3, 2013 – jul 17, 2015)

Description:

The second phase focuses on the post-Battle of New York exploits of the Avengers and S.H.I.E.L.D., and also introduces more heroes, including Falcon, Quicksilver, Scarlet Witch, Vision, Ant-Man, Wasp, and the Guardians of the Galaxy (consisting of Star-Lord, Gamora, Drax the Destroyer, Rocket Raccoon and Groot) and further explains the origin of the Infinity Stones. In Captain America: The Winter Soldier, the terrorist group HYDRA is revealed to have been operating within S.H.I.E.L.D., resulting in the agency's collapse. Now acting without assistance from S.H.I.E.L.D., the Avengers work solo to bring down HYDRA, but unintentionally spawn a more dangerous adversary in the form of the hostile artificial intelligence, Ultron.
