Umbrella Corp.
As far as I know Resident Evil 0, 1, 2 and 3 are the games that are about the T-Virus.
For information about the Resident Evil T-Virus, Planet Resident Evil has a complete explanation of the history of the virus and how it is expanded upon in each game.
Rabies Virus.
Resident Evil 4 is completely unrelated to the T-virus; instead, the "infection" is a different parasite called Las Plagas (the plague).
The T-Virus or Tyrant Virus oh scary i know
yes quite possibly as we continue research in bioengineering
The T-virus was created by Umbrella. It was initially made by James Marcus. After it was made, he was killed and William Birkin took over as the main researcher and scientist involved in the virus work. If you want more information I suggest you take a look at the resident evil wikia or playing Resident Evil 2. :]
James Marcus (queen leech) poisoned raccoon citys water supply with the t virus via the leeches which he controled. then he overwhelmed the ecliptic express with leeches.
the cells in resident evil
The Umbrella Corporation, of which, albert wesker is the chairman There is also Tricell A rival company WiiPharma is also a pharmaceutical company in Resident Evil Degeneration that made a cure for the T-Virus as well as experimenting with the G-Virus. WiiPharma was brought out by Tricell due to bankruptcy.
Wesker started off as a researcher for the T-Virus, after he had escaped Racoon City when the T-Virus broke out, he realised how powerful the T-Virus was and how he could use the T-Virus experiment to help him succeed. He injected himslef with the T-Virus, oblivious to the effects it would have on him. In Resident Evil 5 he is the vice president of Umbrella Coorperations. He develops a new experiment called "Uroboros", the extraction of plant energy to be then mixed with a new formula, much more powerful than the T-Virus. He planned to use the Uroboros experiment to take over the African Continent then the world. no wesker did not inject himself he was one of the wesker experimental children he was already strong to begin with but their was problems with the wesker children they needed to be injected every now and then but it was not the t-virus. William birkins was the one who kept him in check with his medicine hence the reason to why he did not die by the hands of tyrant in part 1 he was always going to be evil because he wanted to be known as a god
You have to go to school to be a scientist and try to cure cancer or aids and screw the formula up completely and turn everyone into zombies.
