Canon in Resident Evil

Due to multiple Scenarios featuring alternative plots, one Scenario is rendered non-canon. Here, the Actual Canon is revealed.

Resident Evil
The actual canon scenario is Chris's. This explains Wesker's hatred for Chris.
 * Chris saves Richard Aiken's life by getting Rebecca the serum.
 * Richard Aiken's official death would be being eaten by the mother Neptune.
 * Wesker kills Enrico Marini
 * Rebecca gets lost, but manages to follow Chris eventually down to the laboratory.
 * Wesker shoots Rebecca and points the gun at Chris.
 * Wesker activates the Tyrant but is impaled by it.
 * Rebecca reveals she was wearing bullet proof armor.
 * Rebecca would survive the first Tyrant T-002 confrontation and follow Chris who meets up with Jill and Barry.
 * As the goal is to get all of your allies aboard the Helicopter, Jill, Rebecca and Barry survive along with you in Chris's Best Ending.

Resident Evil 2
The "Claire A, Leon B" scenario is the canonical scenario in this game. This is due to the fact that in the Death's Door scenario in Umbrella Chronicles, Ada Wong is shown dying, with Leon next to her. In Leon A, Claire B, she fell down into a slag.

However as stated in the 'Death's Door' scenario, Ada Wong retrieved not actually a vial containing the G-Virus, but instead a G-Virus infected tissue fragment of William Birkin as she did not have Sherry Birkin’s pendant containing a G-Virus as Claire tossed Sherry’s pendant into a molten steel pool as seen in the "Leon A Claire B" scenario. According to Wesker's Report Ada Wong's death is by falling, which is also in Claire B, Leon A, as in Claire A, Leon B, Ada is killed by a Tyrant by being slammed on a control panel, breaking her vertebrae, and is shown bleeding to death and the chances of surviving are too low without Weskers "infection" which she didn't have.

Resident Evil 3
The Canon is Jill falling and then "allowing" Nicholai to survive. His survival coincides with him being mentioned as alive in Gun survivor 1 files which some were "made" after October 1st, 1998 (his death if you don't fall). Also by missing the helicopter by falling, the Canon is Jill and Carlos escaping on a helicopter piloted by Barry Burton.

Resident Evil 4
As "Separate Ways" is considered canon, then as Ada kills an El Gigante just after the Cabin battle, and in the same place as the route where Leon gets attacked by an El Gigante, then the canon is taking the route through the Camp site.

This also means that the Bella Sisters may have survived their confrontation with Ada as they fight Leon later on in the camp site.

Then again, as they are seen on their own, and on different levels, it is possible that was a third Bella Sister.

Umbrella Chronicles
A possible way to make some of the chapters canon would be if they were actualy recreations made by Wesker, explaining his Narratives and the alterations' in the storylines. (ie. #3, Wesker could have known about Jill + Carlos going on a Train, Killing the Gulp Worm, Exploring the RPD and Killing the Nemesis. from survivors notes). Though this possibility is almost completely shattered by the fact that the Mansion Incident shows Jill + Chris working together directly, with no help from Rebbecca or Barry.

This also shows Chris as the canon character in Resident Evil, with Rebecca and Jill escaping. However, Barry is known to survive due to a storyline in 3 involving Nicholai either surviving or dieing.

As Survivor is already classed as canon by Zero, and ties in with the other games, and nicholai survives... then Barry must be alive to save Jill and Carlos.

Wesker -being underground- would not know whether Barry survived. Howether, although unseen, it is possible that between defeating Tyrant and the helicopter taking off, Barry could have made it to the helicopter and entered the Cockpit. This can be possible as the cockpit was not seen in the cutscene, only Jill, Chris and Rebecca.

Outbreak
Outbreak is very complicated when it comes to finding which character could make the scenario canon. However the canon is with the characters all (?) surviving. Sometimes it can be explained by how the ending is as a canon player's ending for a scenario is usually different from the other characters.

In some scenarios, there is a fourth Survivor. This 4th person is the canon character. Howether, they will either be killed off away from sight, or will stay at one place claiming to be "tired".

Outbreak File #1

 * Outbreak - Kevin Activating the bomb - explained by bomb craters' in End of the Road and Raymond stating that he is surprise the player is alive (makes more sense if the person he speaks to is Kevin).
 * Below Freezing Point - Yoko as main player
 * The Hive - Leech man killed.
 * Hellfire -
 * Decisions, Decisions - George as Player, escapes with Daylight - Has ties into the Storyline. Yoko as one of the AIPCs, survives- Has more ties with scenario (ie. greg).

Outbreak File #2

 * Wild Things - Cindy.
 * Underbelly - Jim - has ties to storyline, train ending includes extra info.
 * Flashback - Alyssa - discovering truth about Kurt's death, wanting revenge.
 * Desperate Times - Kevin - has ties into storyline.
 * End of the Road - David saving Linda, killing the Nyx, making a bridge for Linda and escaping in Jeep.

Dead Aim

 * Bruce + Fong Ling survive and escape the ship together, and are saved.

Gaiden
The entire game is non-canon.
