Alexander Isaacs (clone)

Dr. Sam Isaacs was an Umbrella Corporation scientist, in charge of the Nemesis Program, and later, the Umbrella Science Division. He appeared briefly at the end of Resident Evil: Apocalypse and was the primary antagonist in Resident Evil: Extinction. He was portrayed by Iain Glen in both films.

Description
Sam Isaacs was a tall, middle-aged Caucasian man of British background. He had sea-green eyes, and dark blonde hair. Dr. Isaacs was employed by the Umbrella Corporation sometime before the Raccoon City Outbreak. He greatly disliked his immediate superior, Major Timothy Cain, a feeling that Cain returned. Isaacs blamed Cain for the Global T-Virus Outbreak, as Cain was the man who ordered the Hive to be re-opened.

Personality
Dr. Isaacs was a man of cool temperament, being intelligent and rational. After the Global T-Virus outbreak, he worked for the good of mankind under Umbrella chairman Albert Wesker, trying to locate Project: Alice and take of sample of her blood, thus creating a more effective cure to the T-Virus. His methods were unorthodox, however, and he regarded his work with a higher priority than the lives of his colleagues or a few civilians. In fact, one might go as far as to call Isaacs selfish, cowardly, and cruel.

This is evidenced by the fact that after the initial test of his serum designed to domesticate zombies failed and the zombie went berserk, killing one scientist, Dr. Isaacs quickly slipped out of the room, locking the doors and sealing a second scientist inside. That scientist could have easily escaped, had Isaacs quickly let him slip out while the enraged zombie was preoccupied by feasting on the first. However, Isaacs coldly watched as the man was ripped apart and eaten alive by the zombie, coolly running his fingers through his hair. His instincts for self-preservation also showed itself during the ambush in Las Vegas when Alice attacked the Umbrella tent. Isaacs quickly fled to the nearby helicopter, leaving his colleagues to die. Isaacs maintained a wary relationship with Alexander Slater, who did not much like the scientist.

Raccoon City Outbreak
Immediately following the disaster in The Hive, it was Isaacs who, at Cain's direction, experimented on Alice and Matt Addison. But disaster struck when Cain unwisely chose to re-open the Hive, despite the containment procedures. Zombies and Lickers escaped the facility, and the Tyrant virus overran Raccoon City, with Alice and Addison, now subjects in the Nemesis program, still inside.

Following the bombing of Raccoon City, Isaacs was dismayed to learn that both Alice and Addison were dead. But he was able to recover Alice's body from the wreckage of the helicopter she used to escape, and moved her and his work to an Umbrella facility in Detroit. After three weeks of experiments, Alice was revived with incredible new powers. Unfortunately, she retained her memories and escaped, being rescued by Jill Valentine, Carlos Olivera, and Lloyd Jefferson Wayne. But Isaacs had one last trick up his sleeve, and as Alice makes her escape, he activates "Project: Alice".

Global T-Virus Outbreak
Umbrella soon had bigger problems than one escaped experiment, however. It was soon discovered that the T-Virus had escaped Raccoon City, and began spreading rapidly. The world was overrun in short order, the only survivors being the civilians who stayed on the road, and Umbrella Corporation employees, who took shelter in underground facilities across the planet. Isaacs himself took charge of the research in an underground lab in the Nevada desert, trying vainly to track Alice across the wasteland that North America had become over the last five years. All the while, he maintained a combative relationship with Umbrella Chairman Albert Wesker.

Isaacs, who had begun a cloning program to recreate Alice, attempted to use the clones' blood to "domesticate" the zombies, making them tame enough to allow humans to return to the surface. This was possible because, as he discovered, while the zombies hungered for human flesh, they derived no actual sustenance from it, and could remain active for decades or more. The results did succeed in raising the intelligence of the test subjects, but resulted in a stronger infection.

Finally realizing that only the real Alice could bring him success, Isaacs falsified orders from Wesker and took a strike team into the wastes to deactivate and retrieve her. He made camp in the ruins of Las Vegas, setting a trap with the enhanced zombies to kill her so they could retrieve her corpse and take a sample of her blood.

Mutation and Death
The scheme did not go as he had planned. Alice massacred the strike team with incredible speed. After an unsuccessful attempt at deactivating her, Isaacs was bitten by an enhanced zombie. He returned to the lab and was placed under house arrest. He injected himself with large quantities of the Anti-virus, but his condition continued to deteriorate.

Wesker, meanwhile, had had enough and ordered Isaacs' immediate termination. Alexander Slater carried out the order, shooting the scientist in the chest and leaving him for dead. It was too late. Isaacs had already begun to mutate, transforming into a grotesque, tentacled monster resembling a cross between Tyrant, a G-Creature, and Nemesis, who then proceeded to slaughter everyone in the facility, beginning with Slater. Taking action, the facility's AI, the White Queen sealed him in the lower levels.

Some time later, Alice entered the facility, and, after consulting with the White Queen, descended into the lower levels to kill the mutated Isaacs. They fought in a replica of the Spencer Mansion, their fight eventually moving into the reconstructed "Laser Room."

Isaacs taunted Alice, telling her that she was not the future as he had previously thought, saying "I am the future." Alice responded by saying "No, you're just another asshole." and that they were both going to die down there. As Isaacs moved in for the kill, the laser grid activated, controlled by a newly-awakened clone, and sliced him into cubes, putting an end to the deranged scientist once and for all.
