Alexander Isaacs (clone)

This clone of Dr. Alexander Isaacs was a virologist working for the Umbrella Corporation.

Creation
Isaacs was cloned from the real Doctor Alexander Isaacs, one of the co-founders of the Umbrella Corporation. Isaacs became a virologist for the company working with the T-virus.

Raccoon City Incident
Immediately following the disaster in The Hive, it was Isaacs who, at Cain's direction, experimented on Alice and Matt Addison after being pulled from the Tyrant program. But disaster struck when Cain unwisely chose to re-open the Hive, despite the containment procedures. Undead and Lickers escaped the facility, and the T-virus overran Raccoon City, with Alice and Addison, now subjects in the Nemesis program, still inside.

Following the bombing of Raccoon City, Isaacs was distraught 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 pandemic


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 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 as he continued his research into the Tyrant program and domestication.

Isaacs, who had begun a cloning program to recreate Alice, attempted to use the clones' blood to "domesticate" the Undead, making them tame enough to allow humans to return to the surface. This was possible because, as he discovered through tests, while the Undead 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 Super Undead 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 and with the help of Claire Redfield and her convoy (most of whom were slaughtered in the process), she killed all of the Super Undead. After an unsuccessful attempt at deactivating her, Isaacs was bitten by the last surviving Super Undead as he tried to escape Alice's assault on his position. 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 enough and ordered Isaacs' immediate termination. Alexander Slater carried out the order, shooting the scientist in the heart and leaving him for dead. However, it was too late, as Isaacs had already begun to mutate, transforming into a grotesque, tentacled monster based upon Isaac's earlier research 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 Alice clone, and sliced him into cubes, putting an end to the deranged scientist once and for all.

The Final Chapter
In The Final Chapter, Janus is shocked when she encounters what appears to be Isaacs in an Umbrella tank years after his death. Janus quickly realizes that this Isaacs was simply a clone and believes that the one she has encountered is the real Alexander Isaacs. Later, when Janus tells Claire Redfield that Isaacs is coming after them, she is shocked as she too believed Isaacs killed by Janus. Janus explains to Claire how the Isaacs she killed was just a clone.

Personality
Dr. Isaacs was a man of cool temperament, being knowledgeable and rational. After the Global T-Virus pandemic, he worked for the good of mankind under Umbrella chairman Albert Wesker, trying to locate Alice and take a 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 Undead failed, and the Undead went berserk, killing a 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 Undead was preoccupied feasting on the first.

However, Isaacs coldly watched as the man was ripped apart and eaten alive by the Undead, coolly running his fingers through his hair and adjusting his tie. 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.

Appearance and wardrobe

 * NOTE: The following section contains information that appears in the Resident Evil novelizations, which have been classified as non-canon from the primary movieverse

Alexander 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 Incident. He greatly disliked his immediate superior, Major Timothy Cain, a feeling that Cain returned. Isaacs blamed Cain for the Global T-virus pandemic, as Cain was the man who ordered The Hive to be re-opened.

Further notes

 * Isaacs is named after actor Jason Isaacs who portrayed an unnamed doctor from the first film and was created to fulfill Birkin's role in the sequel.
 * This clone appeared to be similar in nature to Janus Prospero, "Bad Rain" and the clones of Carlos Olivera and James Shade in that they were clones of real people, but lacked this knowledge. Instead, they acted as Umbrella employees in various functions. This is indicated by the fact that unlike the other Isaacs clone encountered by Janus, this one was clearly subservient to Albert Wesker and the other Umbrella higher-ups instead of being in charge himself.
