7-X9 was one of the Collector's Gatherers ordered to retrieve Howard the Duck, who had been merged with the Nexus of All Realities. When he sent a message to the ship Howard was flying in to announce his assault, he was interrupted by a message of another assaulter, Skrull Commander K'Rolf.
7-X9 was later killed when the Stranger destroyed all of the ships pursuing Howard to have him for himself. Search this site for: 7-X9 ยท 7-X9 (Earth-616).
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.
