|Alpha Male Darkseeker|
|Appearance||I Am Legend (film)|
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.
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 Alpha 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 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.
The Alpha Male and his horde chased Neville, Anna and Ethan into the basement. The Alpha Male then smeared a butterfly shape on the plexiglass, identifying his mate by her butterfly tattoo, and showing that he simply wanted her back. Neville removed the KV antidote from the female's bloodstream and returned her to the Alpha Male. In return, the male made sure the other Darkseekers didn't attack Neville, and left peacefully with his mate.
