Deal with the Guardians
Star-Lord and Gamora were taken to the Eclector after being abducted by the Ravagers. Once on board, they were interrogated by Yondu Udonta, whom they convinced to help them defend Xandar from Ronan the Accuser's upcoming attack on the condition that Yondu would get the Orb once they had won. Rocket Raccoon, Drax the Destroyer and Groot then arrived in the Milano and threatened to blow up the Eclector with the Hadron Enforcer before Quill alerted them that they had reached a deal.

The three then boarded the vessel and the Guardians and Ravagers began planning for the upcoming battle. The Eclector fired a large ball of energy at the Dark Aster, distracting the Sakaarans for the attacking M-ships to get by undetected.
