To most people, Albert Wesker is a hotshot cop who quickly rose through the ranks of S.T.A.R.S. to become founding member of the S.T.A.R.S. Raccoon City Department. But a select few know his true history; Wesker is actually brilliant scientist.

At the young age of 20, Wesker was chosen by Ozwell Spencer, along with William Birkin, to begin research on a biological organic weapon. Spencer mainted an underground Umbrella lab at his giant estate, and both Wesker and Birkin worked there with him. Wesker and Birkin began work on a young woman named Lisa Trevor, a subject for their attempts to create a virus that would one day create biological weapons. Eventually, they reached their goal with the creation of the T-Virus.

Years went by and Wesker began to lose his focus, and could not keep up with the brilliant Birkin. He decided to leave the lab and join an Intelligence Agency, which later led him to becoming the leader of S.T.A.R.S.

In the summer of 1998 a long dead Umbrella general manager named James Marcus, whom Wesker killed on behalf of Spencer, was seemingly resurrected and let loose the T-Virus in the Spencer Estate in an insane act of vengeance. Umbrella ordered Wesker to get real combat data on the B.O.W.s released at the mansion. Wesker saw this as the perfect opportunity to make a bunch of money and leave Umbrella.

Wesker set up the Bravo Team to crash land near the mansion and then sent his own squad, the Alpha Team, into the crash site, positioning him to collect combat data. Wesker also told Barry Burton that he had his family held hostage and that Barry must do what he's told if he wants his family back unharmed. This, however, was all a lie just to force Barry to cooperate with betrayal of S.T.A.R.S.

While in the mansion, Wesker ordered Barry to keep Jill occupied. When Jill found Enrico, the leader of Bravo Team, Wesker shot him before he could tell Jill the truth. Wesker later shot a defenseless Rebecca in the chest simply because he felt like it.

Finally, Wesker got his best agent, Chris Redfield, alone to show him the ultimate masterpiece of the T-virus, the Tyrant. That is when Wesker revealed his plan to steal the Tyrant and sell it to a rival company, thus betraying Umbrella. He unleashed the Tyrant on Chris, but the Tyrant turned on its master and stabbed its massive claws through Wesker’s chest.

Albert was, essentially, dead, but hell was too good a place for a man like Wesker, and he managed to inject himself with a special version of the T-virus as he was dying. The form allowed Wesker to retain full control of his body but gave him superhuman strength, speed and regenerative ability. Wekser then escaped the Spencer Mansion before it blew without anyone knowing, vowing revenge on S.T.A.R.S., and specifically Chris, for ruining his plan.

In the following months Wesker hid in the shadows. He hired a woman named Ada Wong to retrieve a sample of the G-virus from William Birkin, but she failed in her mission. After the Raccoon City incident, Wesker kidnapped Sherry Birkin instead, who had the G-virus within her body.

A few months later Wesker, and the new company he worked for, decided to go after the T-Veronica virus, which the Ashfords held in their island. Wesker mounted an assault on the island, resulting in another T-virus outbreak. While on the island Wesker encountered his nemesis Chris Redfield. Excited about his chance for revenge, Wesker toyed with Chris a few times even though his first priority was to get the T-Veronica sample. Alexia Ashford was infected with the T-Veronica virus and was superhuman, as well. Wesker tried in vain to kill her; she was too strong. Instead, Wesker took the body of Steve Burnside, a prisoner who was infected with the T-Veronica virus. On his way out, Wesker finally cornered Chris, and picked this moment to exact his vengeance. An epic struggle took place and Chris finally managed to create a barrier between himself and Wesker which allowed him to escape.

Six long years went by, during which Umbrella was destroyed. Wesker decided to build his own “Umbrella” using the samples he had collected over the years. When a parasite known as Las Plagas was discovered in Europe, Wesker sent Jack Krauser and Ada Wong to collect a sample. What Wesker did not know was that Ada Wong was actually a double agent, working for the mysterious “Organization”. She betrayed Wesker and sent him a fake sample of Las Plagas.

Wesker is the most dangerous man on the planet. He has the means to start an outbreak in any part of the world, and plans to eventually have a sample of every major B.O.W. What is his ultimate goal? Can it unspeakable wealth, or is it world domination? All we know is that Chris Redfield is still alive and Wesker will stop at nothing until he is dead.
