Rocket was a member of the Guardians of the Galaxy when they traveled to the Blue Area of the Moon to retrieve the Eye of the Watcher. Here they met Captain America and due to a misunderstanding the group fought with Rocket attempting to blow her up. During the battle, Star-Lord heard her codename and realized she probably wasn't a bad guy but Drax launched her out of the temple before Star-Lord could stop him. Upon her return, she and Star-Lord grabbed for the eye but everyone got a glimpse of destructive future and decided to team up to help save it.
Nothing is known about Ms. Summers, save that she is a young mutant woman whom Bushwacker was contracted to kill by the Marauders. Bushwacker broke into her house and did so. Wolverine found her body and swore vengeance on Bushwacker. Summers was known to be a mutant, though her exact power is unrevealed. Given that the Marauders hired Bushwacker to specifically kill mutant creative geniuses, however, she likely had some sort of superhuman artistic insight.
