Adam-X has the power to "flash fry" or burn the blood of an adversary once it has been oxygenated, usually done by opening a wound on them using his Thet'je blades.
History
Origin
Intended to be the third Summers brother, Adam-X's mother was Katherine Summers who was abducted by 'D'Ken, the Shi'ar emperor, his father. Erik The Red revealed to X-Treme that he was the heir to D'Ken's Shi'ar throne. After his mother was murdered by D'Ken, Adam-X was raised by a farmer named Jonath on the planet Ch'reesharaa.





On Earth

After crashing on Earth and unaware of his own past, Adam-X began working for industrialist, Martin Strong helping bring mutants to a Strong Industries plant where, ostensibly he would give them shelter. In exchange, Strong promises to help Adam-X regain his identity. During this time, Adam-X develops a close friendship with fellow mutant Michelle Balters, also known as Neurotap. Unbeknownst to Adam-X, Strong Industries was, in actuality, funded by Project: Wideawake to develop a means to exterminate the “X” gene that makes mutants. Discovering the truth, Balters flees from Strong Industries. Adam-X is sent to bring her back in.

X-Force had already begun investigating Strong's activities when they cross paths with Balters. X-Force attempts to preserve Balters' freedom but they are momentarily incapacitated by Adam-X's mutant ability. Balters is able to escape with X-Force and provide them with information about Strong.

Although initially meeting as adversaries, Adam-X and X-Force eventually join together to combat Martin Strong, once they discover that he is a mutant himself. Adam-X and Shatterstar, in particular, discover a mutual affinity due to their alien mutant status and love of battle. Membership to X-Force is offered to Adam-X but he declines, choosing instead to find his past and find who he is.

For unknown reasons, Mister Sinister, under the pseudonym of Mr. Milbury, hires Arcade to “test” Adam-X. At the same time, Major Domo hires Arcade to get rid of Shatterstar. Arcade decides to meet the demands of both employers by capturing the two and pit them against one another in Murderworld. After yet again battling one another briefly, Adam-X and Shatterstar join forces and work their way through Murderworld and defeat Arcade.

While traveling in the Canadian Yukon wilderness, Adam-X witnesses Phillip Summers’ plane crash. Adam-X is able to rescue Summers before his plane explodes. Adam-X uses his mutant power to “heat” Summers' blood and keep him warm until he finally manages to carry him to a hospital. They are greeted by Summers' grandson, Cyclops and Cyclops' wife, Jean Grey. The two X-Men thank Adam-X for his efforts and, using Jean’s telepathy, Adam-X is able to share some of his memories with Phillip, showing him the ships he flew while with the Shi’ar.

Adam-X is next seen with Captain Marvel scaling a mountain. The two head for the Aerie, a ship that Adam-X has called home for the last two months. Unaware to both Adam-X and Captain Marvel that they are being watched by the Shi’ar agent, Davan Shakari (aka Eric the Red). Shakari sends the Sidri Hunters to bring them in. Adam-X and Captain Marvel easily fend off the Sidri Hunters.

In his encounter with Shakari, Adam-X learns the most about his past. Shakari explains, “You are dubbed the Forsaken One, Adam – but that was a mistake on the Majestor’s part, those many years ago! Truly had you been rightfully admitted into the family, we would not be in this predicament today. Empress Lilandra sits on the Shi'ar Throne this day, only because Majestor D’Ken was driven mad by his experience inside the M'Kraan Crystal. She was not meant to guide the Imperium. You see, yours is the destiny of power – bred to introduce a hybrid, specific genetic potential into the Shi’ar Monarchy! Adam-X, you were born to rule the Imperium! Who else should be the heir to the throne – other than the living child of Majestor D’Ken?”

Adam-X however, uses his mutant power to “fry” Shakari, causing his body to apparently explode. From there, Adam-X and Captain Marvel part ways, wishing one another the best of luck.

When last seen, Adam-X was still searching the Earth for more clues to his own past.

Dark X-Men

Years later, Adam-X finally returns in San Fransisco, sitting drunk in a bar with other mutants. He is angry that humans are trying to prevent new mutant births and he participates in a riot. Adam is later arrested by Emma Frost and her Dark X-Men





Powers & Abilities
X-Treme is a Shi’ar/Mutant Hybrid that is capable of igniting the electrolytes present in the bloodstream, causing the person to burn from the inside out. X-Treme possesses exceptional control of his power; able to incinerate objects, or simply use the power to create a warming sensation. In order to ignite the electrolytes, X-Treme has used blades to cut the flesh and oxygenate the blood. Whether this is necessary or simply makes the power more effective, remains unknown.





Adam is a Shi'ar/human hybrid, and as such possesses the traits and abilities of both species. His strength is slightly superhuman, and his stamina and endurance is many times that of a normal human. Adam's speed and reflexes are far superior to both human and Shi'ar. As he is also half Shi-ar, who are evolved from giant birds of prey, he also possesses superhuman senses, agility, flexibility, dexterity, coordination, and balance which are standard to that alien race.
