Jack Krauser

"Well, if it isn't the bitch in the red dress"

Jack Krauser is a character from Resident Evil 4, though not much is known about him. He used to be a Government Agent alongside with Leon S. Kennedy, but two years before Resident Evil 4, he faked his death in a helicopter crash, and now he is working for Albert Wesker and pretending to work for Osmund Saddler, the leader of the Los Illuminados.

Purpose
In Resident Evil 4, Krauser is sent by Wesker to the Ganados' island to infiltrate the cult group Los Illuminados and steal a sample of the Las Plagas parasite (preferably a Master Plaga). Krauser is supposed to work with Ada Wong, another agent sent by Wesker, however, they don't see eye to eye; Krauser believing that Ada is untrustworthy and may betray Wesker. Krauser is ordered to assassinate Leon S. Kennedy but fails due to Ada Wong's intrusion (thus increasing his paranoia about her), he later duels Leon to what appears to be 'death', only to re-surface later on (within the 'Separate Ways' mini-game ) injured but still alive.

He is then terminated by Ada Wong, though he could be still alive due to the fact that he didn't die the first encounter, but may have died when the Island exploded. An interesting note is that after completing a Mercenaries playthrough as Krauser, the score board shows him taking cover as the island explodes. This picture could also refer to Krauser taking cover from the tower that he and Leon fought on which also explodes, so this does not prove that Krauser is alive.

Boss


Leon S. Kennedy fights Krauser in Resident Evil 4 twice. The first battle is somewhat simple: the player must just press two different button combinations as they appear in Leon and Krauser's knife fight cutscene.

Later in the game, Leon must battle Krauser again in a large ruins area where Krauser appears and disappears, shooting Leon all he can while the player must gather 3 insignias to open a gate to advance further. It is also interesting to note that in that fight exclusively, the knife does roughly 40 times as much damage to Krauser as it would normally (while a rocket launcher does the same damage as a normal knife slash). This is most likely added to encourage the player to finish him off with the knife, since they seem to have a rivalry in knife combat, or that Krauser's Las Plagas parasite is revealed, as he is not wearing a shirt.

After Leon gets the second insignia, Krauser's arm mutates into a large bladed claw that is completely bulletproof and deals massive damage. He can use it to shield his upper torso, but his legs remain vulnerable to attack.

At the end of the Assignment: Ada minigame he appears as the final boss in the same form Leon fought him the second time.

In the side story Separate Ways, Ada confronts Krauser after Leon's final encounter with him. Ada claims that Krauser's been killed, and a body is shown.

Mercenaries
In the minigame of Resident Evil 4, The Mercenaries, Jack Krauser is unlockable. To unlock him, one must get a Four Star Rating on Salazar's Castle level.

Krauser is powerful in The Mercenaries. He wields a bow and arrow and has a mutated arm in which he can mutate to a deadly level when it is glowing red. The arm can attack once when mutated, but can destroy any enemy in one hit, even the Special Bosses such as Super-Salvador and Garrador. Krauser's double-roundhouse kick is also devastating and his knee special move is almost always a guaranteed kill.
