Humanity is stagnant. Dying. I would give it one body. One mind. Think about it--no more conflict. No more disease. No more suffering. Don't you see? I'm giving it a second chance." ―Mercer explaining his goals to Heller at their final confrontation [src]

His official bio also states his "personality traits" which are: distant, predatory, super-intelligent, terrifying, vengeful, blank, and searching. [5] Numerous Other Unknown Skills: Due to having consumed a vast number of individuals over the course of both games, Mercer likely has access to a number of skills which were either unexplored or simply never used due to either being completely useless or simply not fit for the situation at hand. It is unknown just what other skills he knows, as well as, how vast his knowledge on various subjects really is. Alex walked off thinking to himself "What have I become? Something less than human, but also something more..." Later, Manhattan is seen in a recovering state, with the virus almost completely destroyed. Prototype 2: The Anchor Part 1 During one of Alex and Dana's meetings, Dana was kidnapped by a Leader Hunter, a larger and stronger version of the normal hunters. Alex pursued this Leader Hunter across the city, but was ultimately unable to rescue Dana. With the help of Dr. Ragland, Alex located and consumed the same Leader Hunter that kidnapped Dana, learning of her location in the core hive in the center of the city. Alex was eventually able to penetrate the hive, where he confronted Elizabeth Greene. Alex begging for help with Dana Infected Animals}: During the Prototype tied-in comics, it is shown that animals are capable of being infected by the virus. Their mutations vary between different animals. However, it is shown that they gain increased strength and durability.My name is Dana Mercer. I'm Alex Mercer's sister. And I have information about your daughter." ―Dana upon speaking to Heller for the first time. [src] Many fans of the series have speculated that Mercer could possibly be still alive or that the Mercer that Heller consumed was actually a perfect clone of the original that was created via uncertain means, likely when Mercer regenerated from near-total obliteration by a nuclear bomb at the end of Prototype. Whether or not any of these rumors are true, it is still unclear if Mercer survived his fight with James Heller, or, if the clone theory is true, where the "original" was during the events of the second game or if he is still alive after this point.

The original Alex was a cold monster with no empathy who ultimately unleashed the virus out of pure spite. His actions and demeanor are likely due to his troubled past, which made him a cold individual, both paranoid and sociopathic. On top of that, he seemingly doesn't care about his younger sister, Dana, and is seemingly only using her as a pawn in his plans as well. He rarely takes human cost into account during his actions, being able to murder scores of humans without remorse or hesitation. After surviving the nuclear blast at the end of Prototype, Mercer found himself at an impasse. He considered himself still human, but did not know where or how he fit into the world, and due to the actions of himself and those he had fought against he had begun to lose his faith in humanity. He began to travel as a way to find himself, or to at least find a purpose. Alex, having dinner with Flint and AutumnDr. Harry Gutierrez was another individual who has said Jimmy to James as when he said he has heard so much about James and in which lead to the death battle between James and the bodyguards and Dr. Gutierrez. Defeated, but unconcerned by his impending death, Mercer welcomed Heller "to the top of the food chain" with a bemused tone immediately before Heller consumed him and gained a memory from him. Heller, having become extremely powerful as a result, used an expansive mass of tendrils to destroy all the infected citizens in the surrounding area, saving Manhattan from the "Mercer" virus in the process.

During the final battle of Prototype 2, Mercer is shown to be much taller compared to Heller (about 8'-9'), possibly because of Mercer consuming his Evolved. Elemental Resistance: Heller's altered physiology endowed him superior resistance to fire and electricity than prior to his infection in the same vein with Mercer. Considering that Mercer regenerated from a literal puddle of radioactive biomass after being caught in a nuclear blast, his severed limbs possibly could regenerate if touched by organics. It is also possible that during his regeneration at the end of the first game, some of Mercer's biomass did not join the rest but regenerated into a new and separate body, which would have resulted in a second Alex Mercer and would therefore confirm the clone theory. Dennis Detwiller, the senior designer and writer of Prototype, said there is "no cute fuzzy bunny in Alex Mercer's future". This quote could be read as a hint at Mercer's eventual death at the hands of James Heller, although Detwiller himself left Radical Entertainment in 2009 and was not involved in the making of Prototype 2.

Stealth Master: Due to Mercer’s altered physiology, Mercer is a master of stealth. His ability to shapeshift allows him the ability to move around undetected allowing him to move around in public and sneak pass potential chasers without being noticed, combined with his parkour skills and the memories of the people he has consumed. Before long, the military began to deploy a new biological agent, Bloodtox, engineered to kill the virus and its hosts. [2]
