William Birkin, otherwise referred to simply as G, is featured as an enemy in Resident Evil 2, the story being reimagined for Resident Evil: The Darkside Chronicles, Resident Evil: Operation Raccoon City and Resident Evil 2 remake. Already in Resident Evil Resistance, although Birkin returns as an enemy, he can be playable.

Resident Evil 2 (1998)


As this form does not possess any natural weapons, G1 instead makes use of his superhuman strength to tear a pipe from a guardrail to swing about and attack with. The monster can swing the pipe in a powerful two-swing attack, or raise it and bring the pipe crashing down with enough force to kill a character in one hit. Once defeated, it will hit the air with the barrel for a few seconds, so wait until it drops off the platform railing before it can pass.

The creature's attacks include:

  1. A double swipe where it hook swings at you then backhands;
  2. A single hook swipe;
  3. If the character stands still it will stab straight and/or;
  4. If the character stands still it will hook punch with its left hand.
  5. If the character is on low health, G2 will perform a gut stab incredibly similar to that of the Tyrant (T-002 Model) from the previous game. As a matter of fact, the second stage has often been compared to a Tyrant.

It will perform 3 swings with its large claws or perform a straight stab. During the fight with G2, the player can also use the Proposed Water Purification Room's large crane against it to deal hefty damage. One must be careful as failing to avoid the crane trap being set against G2 will result in an instant death. Aside from that, G2 can also perform a grab attack, one must use a sub-weapon to be free or else will result again in an instant death where G2 will throw the player out of the map.


This stage has similar attacks to its previous stage. Mostly G3 attacks through single swipes with its massive upper arms, and jumps great distances. Also, if it walks towards its victims with its arms spread, it will attack with a powerful 4-hit combo. Its two death scenes involve it impaling the victim with its lower arms before shredding them with its upper arms, or decapitating them. Try never to stay at the end of the corridors, so as not to be trapped.

B5F cargo room (16)

This stage moves around with an odd gait, often compared to a dog or wolf. It jumps about from pillar-top to pillar-top, and often jumps down in front of a character. It will either swipe at them with a small forearm, or more dangerously, it will grab them and gnaw them with its massive fangs. In some endings, this is the final boss. It is important to be careful not to be "chewed" by it as this blow can kill instantly depending on the status of Leon or Claire.

Umbrella Train (Rear Carriage) (12)

This final form attacks using its massive tentacles and swiping through the train car in an attempt to push a character into his mouth. The creature is also pulling itself into the train, giving this fight a time limit: if the monster isn't killed after a certain time has passed, it will catch and devour Leon or Claire. However, if Leon or Claire is out of ammo/does not have any weapons and the monster comes close to them, the monster will die on its own.

Resident Evil: The Darkside Chronicles


G1 now can throw his pipe, or swing it multiple times in rapid succession. The creature is also more clever; when Claire and Leon jump on top of a structure, rather than trying to climb to reach them, G merely smashes their platform, shaking it and throwing off their aim, before striking one of them with the tip. Lastly, after throwing its pipe, it will pick up a character and strangle them to death. If stopped, G will drop them off the side of the bridge before repeatedly swinging at them.


All the player really have to do is aim for the eye, and when that's closed, his head. There are no dodge prompts here, so the only way to stop him from hitting is to do enough damage to him to stun him. G2 will try to hit you once, and if he succeeds, he'll prepare for a backhand. When the monster back is facing the player, there's a small eye on one side of his back, so shoot for that if can. When G2 health is about halfway down, run a bit to one of the walkways. He'll jump up at the player, so have to shoot him enough to stop him from hitting. Keep shooting him until he falls, but be careful, because there will be a licker to kill right after this.

William Birkin (7)

G3 will perform powerful jumping slashes and is very acrobatic than in the original game. It will even perform a roundhouse kick, as well as a swipe with two arms (i.e. both right arms). As always, shoot the eye, although it's smaller and harder to hit now. If the player have a hard time doing that, just aim for his head/chest with a powerful weapon. If run from the monster, he'll come from above and attack the player, then his'll go to another walkway. Be prepared for button prompts. After the player defeat this form, he'll fall over the edge.

William Birkin (8)

This stage is slightly revised. Now it can climb walls and is much, much larger than it was before. The many fangs in its maw now twitch and it expels acidic slime from its mouth. The stage mostly employs pouncing from a great height onto Leon and Claire, occasionally destroying sections of the walkway. The creature eventually grabs one of them in order to devour the victim head-first, but fails. Eventually, one of its pounces fractures the walkway, causing the survivors to shoot at it while it dangles. The monster then slaps the catwalk and knocks them down to its level, allowing it to attack with acidic vomit and slashing with its massive talons. In a short time, G4 falls off the catwalk and vanishes from sight.


G5 is more powerful, and much more aggressive. It fights by hurling wreckage of the train car at the characters, as well as using claw-tipped tentacles to slash at the players. The monster also has two incredibly bizarre attacks: it can vomit up recently consumed zombies to fight the characters, and eject its own mouth, extending it to about ten feet before striking the players.

Resident Evil 2 (2019)

RE2make Machinery (8)

In remake, G1 will perform a three-swing as its standard attacks. It will become far more aggressive when its large eyeball is exposed, relentlessly pursuing the player until it gets the opportunity to grab them. Upon getting grabbed, one must use a Sub-weapon to escape, otherwise it will deal heavy damage. At certain points, G will hide itself in the fog above, wherein he becomes untargetable until he ambushes the player.

RE2make Propopopo (2)

The place where the battle takes place has a container, which the player must use to knock it down after dealing enough damage to it. If used before, G2 will be able to recover, meaning the player will have to repeat the process. In addition to this, standing in the fire line of the container when using it, will lead to the player instantly dying too. On Standard mode, knocking Birkin down twice when shooting one of the orange eyes and then catching him with the container should be enough to defeat him. In Hardcore mode, the playermust knock it down at least three times. The flamethrower and Magnum are very good weapons with Leon, whilst with Claire the submachine gun helps a lot due to its high fire rate.

RE2make Bioreactor Room (10)

The creature retains most of its regular attacks of the original Resident Evil 2 but now, at certain points, it will grab a debris to throw at the player (dealing high damage if they connect with the player). Destroying one of its eyeballs whilst it is grabbing something to throw will interrupt it from doing so. When grabbed, the player must use a sub-weapon or else, G3 will instantly kill the player by viciously ripping the player character to shreds with its sharp claws. If playing as Claire, creating acid grenade rounds will make the battle a cakewalk since acid rounds temporarily stun William. In Hardcore, about 30 rounds will be enough to defeat William.

RE2make Turntable (11)

In remake, G4 is only faced in the Claire's scenario. It shares a similar moveset like the ones from The Darkside Chronicles, while battling it on the Turntable. It will sometimes climb on the walls before jumping down to crush the player. The player can however prevent G4 from climbing the walls by dealing enough damage to it when it is doing so, causing it to fall down. Its other main attack involves it crouching before charging towards the player to deal heavy damage.

G5 battle RE 2 remake

Use whatever is left against him, then shoot nonstop. Save the strong weapons for when he opens the giant orange eye in the center. Keep your distance, because if it reaches the player, it's instant death. The player must keep on firing and attacking G5 until its large eyeball is exposed to completely defeat it.

Resident Evil: Resistance

William Birkin (in G1 form) is Annette Birkin's Ultimate Skill as Mastermind. After Nemesis, he is among the most effective B.O.W. to devastate the survivors, being excellent to be placed in points of convergence or small rooms. He has four moves:
