Jack Krauser

Jack Krauser is a character from Resident Evil 4, though not much is known about him. He used to be an army veteran, but now he is working for Albert Wesker.

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 (prefferably 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 assasinate Leon S. Kennedy but fails due to Ada Wongs 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 'Seperate Ways' mini-game ) injured but still alive.

He is then (seemingly) terminated by Ada Wong.

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.

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; but whether or not he's actually dead has not been confirmed. It's worth noting that at the end of Krauser's Mercenaries mini game, he is shown having escaped the island, watching it explode. This hasnt been confirmed to be canon.

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 Mercinaries. 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.

Other Appearances
He reprises his role in TB's Resident Evil series. Krauser instead is in a S.T.A.R.S. team, Combative team, but still is working for the enemy, Umbrella.
