James Marcus

Now I will have my revenge on Umbrella, and the world will burn in an inferno of hate!

James Marcus was a brilliant scientist who became one of the three founding members of the Umbrella Corporation, and creator of the original strain of the tyrant virus.

Early Years
However, something wondrous happened, it took the t-virus inside of my queen years to procreate my new life.

Born in 1917, Marcus befriended Edward Ashford during his studies at school, where he quickly proved himself an expert on biology and virology. After leaving school, Marcus and Ashford became research partners, and began pursuing research into the Progenitor virus, and enlisted the aid of one of Ashford's close friends; Lord Ozwell E. Spencer, who provided enough funding that they discovered the virus in 1967.

Marcus and Ashford held ideas for the new-found virus to benefit the medical community, while Spencer instead believed it could be used to create a powerful biological weapon.

To mask their research and motives, the three scientists formed Umbrella Chemical, Inc., drawing massive profits and political authorization for them to continue their research. All of their sinister intentions were camouflaged with the image of a benevolent, trustworthy and highly-respected pharmaceutical company, which itself soon gained in prominence.

In 1968, Marcus reached the position of General Manager and Research and Development Director, and was appointed head of the Umbrella Corporation Management Training facility in the Arklay Mountains. While Ashford assisted him, Spencer took over the corporation's financial duties.

Marcus continued his research into the virus, and in January 1978, managed to create the t-virus by combining leech DNA with the Progenitor virus, which in turn would lead to further research into Progenitor and the later discovery of the G-virus and creation of Umbrella's line of B.O.W.s. This remarkable find gave Marcus much attention and prestige from his fellow researchers, though Spencer, intimidated by his findings, began to grow increasingly paranoid of Marcus.

Later that same year, taking a break from his research, Marcus took to two of his most promising researchers; William Birkin and Albert Wesker. While teaching them to be responsible scientists, Marcus intended to use his findings to gain a place on the company's Board of Directors. In July, before Marcus could present them, Spencer intervened, by officially closing down the Umbrella training facility and transferring the t-virus Project's development to the nearby Arklay Research Facility.

Continuing his Experiments
Even though the training facility was closed down, Marcus continued to work there. During the 1980s, Marcus was all but confined to the training facility. Continuing the virus' experimentation, such as creating the first B.O.W's (including the Plague Crawler, the Lurker, and the Eliminator), and learning more about the t-virus' potential. Soon, Marcus' isolation took its toll on him mentally, eventually using his own assistants as guinea pigs for his leech experiments. After no less than 20 of them were sacrificed, Marcus made tremendous strides towards creating an off-shoot of the t-virus project: the Tyrant Program.

Assassination
Spencer's paranoia peaked, and he ordered Wesker and Birkin to assassinate Marcus whilst he least expected it. This occurred on a mundane day in 1988, when Wesker, Birkin and a team of Umbrella Security Service commandos stormed into Marcus' laboratory, and gunned him down. As the assailants departed, Marcus' body was disposed of, thrown in the waters of the facility's sewage plant. However, at the time of his assassination, Marcus was conducting an experiment on a live leech, which escaped from its containment unit after it was broken by gunfire. The leech entered his body via his mouth and bonded with his DNA, allowing him to slowly regenerate into something no longer human. In terms of appearance, Marcus was reborn with the physical characteristics of himself in his early-20's. With time, Marcus learned to control and expertly manipulate the leeches, considering them his children.

Vengeance
Marcus, consumed with hatred, vowed a terrible revenge on Spencer and all of Umbrella, inc. for their attempt on his life that cost him his humanity. To this end, Marcus unleashed the t-virus upon the Arklay Research Facility and the Management Training Facility, and then attacked the Ecliptic Express, a personal company train devoted to luxuriously transporting Umbrella employees.

All the inhabitants of the train were killed and transformed into Zombies due to the high concentrations of the t-virus Marcus unleashed. Marcus effortlessly shirked off USS Commando attempts to clean up the source of the biohazard. In control of the situation, Marcus displayed a video transmission across the training facility, where Wesker and Birkin remained in hiding from the zombie population, threatening his murderers that they would pay for their act of betrayal.

Death
When S.T.A.R.S. Bravo team Officer Rebecca Chambers and Ex-USMC Second Lieutenant Billy Coen were lost in the forests of Arklay, hunted by B.O.Ws, they soon encountered several creatures that mimicked Marcus during their search of the train and training facility. Eventually, Rebecca and Billy confronted Marcus himself, in an underground location under the facility. After revealing details regarding his mortal demise, Marcus uncontrollably mutated into the Queen Leech. Although it was impervious to small-arms fire, Rebecca and Billy managed to defeat it by exposing it to sunlight, its one weakness, and Billy finished off what remained of James Marcus with a single bullet.

Legacy
Though Marcus did not live to see it, the events he had set in motion eventually led to Raccoon City's destruction and the deaths of most of its population, along with the downfall of the Umbrella Corporation, which turned Spencer into the world's most wanted fugitive. This ensured Marcus had gained his vengeance on Spencer and Umbrella after all. However, it also resulted in Wesker's rise to power.
