X-Treme (Adam X) • Adam Neramani
Adam X, also referred to as X-Treme, is a mutant in the Marvel Universe.
The character, created by Fabian Nicieza and Jeff Johnson, first appeared in X-Force Annual #2 (October 1993).
Within the context of the stories, Adam X is a half-human and half-Shi'ar who possesses the mutant ability to ignite the oxygen in another person's blood. He initially encounters X-Force while he is working for Martin Strong. Initially unaware of Strong's connection to Project: Wideawake, Adam eventually works with X-Force when the full extent of Strong's plans are revealed.
The character has made sporadic appearances since then with little background added. Some overall plot threads from the X-Men related titles were touched on such as Mister Sinister being interested in Adam X, and the former Shi'ar emperor D'Ken being his father. The character was also an aspect of the "third Summers brother" plot element. When introduced, Adam X was thought by readers to be the son of Katherine Summers and Shi'Ar Emperor D'Ken. While this origin was never confirmed in the comics themselves, Adam is half-human, and Katherine was the only known human woman in Shi'ar space at the time. X-Men vol. 2, #39 (December 1994) featured a story about Adam discovering Philip Summers (father of Christopher Summers and grandfather of Cyclops and Havok) in the Alaskan wilderness and feeling an unusual connection to the old man.
Nicieza later confirmed that he intended Adam X to be the half-brother of Cyclops and Havok
