18th Kree Diplomatic Gestalt
The 18th Kree Diplomatic Gestalt are a group of reality hopping Kree Peacekeepers, they were only one reality away from home (possibly either Earth-615 or Earth-617) when their ship (a dimensional schooner called "The Marvel") was shot down by men working for The Midas Corporation. The ship crash-landed on Earth-616, killing everyone with the exception of "Ensign Marvel" who is known better as Noh-Varr.
Academy X
As a result of M-day, only 27 of the 182 students enrolled at the Xavier Institute for Higher Learning still retained their powers. In response to the increasingly desperate situation that mutants now faced, Emma Frost disbanded all the former training squads (most of which had lost much of their membership to the Decimation) and integrated those students she deemed capable of combat.
