A young Sh'iar warrior of largely unknown background, the alien Deathcry was exiled to Earth for reasons that are still mostly unclear. 

     She was assigned by Shi'ar Majestrix Lilandra to protect Lilandra's allies, the Avengers, from assault by their mutual enemies, the Kree. 

     After helping the Avengers weather the Kree's initial assaults, Deathcry often aided the Avengers in their subsequent missions, residing in Avengers Mansion. 

     An illegal (and underage) alien on Earth, she was considered the Avengers' ward and formed close friendships with Vision and Hercules. 

     The latter Avenger eventually helped her return home to the Shi'ar Empire when she was given a chance to do so, and she has not worked with the Avengers since then.
