Peter Quill, Gamora, Drax, Rocket and Baby Groot are hired by Ayesha, the leader of the Sovereign race, to protect their unique and expensive batteries from an inter-dimensional beast, who wants to feed on them, and after they succeed,
their reward, as planned, is the surrender of Gamora’s sister Nebula, to them, who was ready to be killed by the Sovereign, for trying to steal their batteries. Nebula hates Gamora, and she keeps showing that to her, while Rocket has stole
some batteries from them. As a result, the Sovereign are attacking the Guardians, who were leaving their planet, with a fleet of drones. While the Guardians’ ship is ready to be destroyed, a man over a ship destroys all the drones. This man
is Ego, Peter’s father, who invites them to his planet.
