Nebula (What if Nebula joined the Nova Corps?)

Nebula is a former member of Black Order and the adoptive daughter of Thanos. When Ronan the Accuser killed her father and sister, Nebula was rescued by the Nova Corps and recruited by Irani Rael. As a Nova corpsman, Nebula investigated the killing of Yondu Udonta and discovered Rael's conspiracy to disable Xandar's planetary shield and allow Ronan to invade the planet. Together with Howard the Duck, Korg, Groot and Miek, Nebula successfully stopped Ronan and the corrupt Nova corpsmen, ending Xandar's lockdown for good.
