The Alpha Male Darkseeker was the main antagonist of I Am Legend. He was the leader of the Darkseekers and the arch-enemy of Dr. Neville, who kidnapped his mate in order to test strains of his serum in order to find the cure to the KV. This motivates the vengeful and ruthless Alpha, and the Darkseekers to attack Neville numerous times. The Alpha Male Darkseeker is indirectly responsible for the infection and subsequent death of Neville's companion Samantha and led the final assault to Neville's home and makeshift lab where Neville kills the Alpha, the Alpha Female and what's left of the Darkseekers with an M67 grenade at the cost of his own life to ensure the protection of Anna and Ethan and the cure to the Krippin Virus.
When KV broke out, the Alpha Male was infected and turned into a Darkseeker.
He became the Alpha Male of a colony of a few thousand Darkseekers living in the derelict Manhattan.
In 2012, three years after the KV outbreak, the Alpha Male and his colony were living inside a deserted building. When the colony was discovered by Neville, the latter used a snare trap to capture the Alpha Male's mate. The enraged male attempted to rescue her from Neville, but he was kept at bay by the sunlight.
The following night, desperate to rescue his mate from Neville, the Alpha Male took one of the mannequins outside of a local video store, and set up a duplicate of Neville's snare trap for him in front of the Grand Terminal Station, with the mannequin as bait.
The Alpha Male retreated into the Station at dawn from the daylight. During the day, Neville fell for the trap. At dusk, when it became dark enough for the Alpha Male to exit the station, he emerged and unleashed three infected dogs on Neville and Sam. Neville and Sam were able to survive and kill the dogs, but not before one infected Sam, who later became aggressive and was reluctantly killed by a heartbroken Neville after the serum didn't affect her.
That night, a horde of Darkseekers led by the Alpha Male attacked Neville's "office" in South Street Seaport, where Neville waited with Sam everyday for years during midday for any survivors, in search of Neville. There, a grief-stricken and raged-filled Neville suicidally ambushed and killed many of them as vengeance for Sam and to die by their hands out of grief and loneliness over Sam's death. Despite killing many Darkseekers, they were eventually able to overwhelm him. The Alpha Male approached and prepared to kill a barely conscious Neville, when survivors Anna and Ethan arrived and used UV lights to force the Darkseekers to retreat.However, as Anna and Ethan arrived at Neville's apartment before dawn, the Alpha Male and the other Darkseekers were able to trace them back to there.
The next night, the Alpha Male led and attack on Neville's apartment, during which the Alpha Male was able to break in and viciously attack and battle Neville. Though the Alpha Male had the upper hand in the fight, Neville was eventually able to force him to retreat back outside.
Later, when the Darkseeker horde was able to pour into Neville's apartment, the Alpha Male and the horde followed Neville, Anna and Ethan into the basement, where the three locked themselves in a plexiglass room from the Darkseekers. The Alpha Male began breaking through the glass, ignoring Neville's reasoning that he could help them. Robert saw the butterfly created in the cracked glass from the Alpha Male which caused him to think of his daughter Marley.
Neville draws a vial of blood from the woman he cured and gives it to Anna, before shutting her and Ethan inside a coal chute in the back of the lab and instructing them to wait until the sun rises before leaving for Bethel. After looking at a photo of his wife and daughter and presumably thinking of his lost "girls" (Zoe, Marley and Sam), Neville rammed at the Alpha Male with an M67 grenade, killing himself and the Darkseekers, ensuring that Anna and Ethan take the cure to the human colony and restore humanity.
