Killer Croc (Arkhamverse)

Killer Croc is one of the antagonist in the video game; Batman Arkham Asylum, Batman Arkham City and Batman Arkham Origins.

Batman: Arkham Origins
Killer Croc makes an appearance as a minor antagonist in Batman: Arkham Origins (taking place a few years before Arkham Asylum). He's one of the assassins hired by Black Mask to kill Batman.

Croc is first spotted by Batman escorting Black Mask through Blackgate after staging a major prison breakout. Batman then witnesses him, under orders from Black Mask, murder Commissioner Loeb by throwing him into the prison's gas chamber and turning it on. Batman then follows Croc and his employer to the roof where Black Mask escapes and the Dark Knight confronts Croc, they then fight on the snowy roof of Blackgate Prison. Batman is first caught off guard by Croc's size and strength and animalistic fighting style. After trying to eat Batman, Croc resorted to throwing giant gas tanks that were being stored on the roof, at Batman. This tactic was his undoing however, as Batman used a batarang to explode one of the tanks as Croc was holding it which temporarily incapacitated him. Batman then knocked him halfway off the roof before brutally beating him for information on Black Mask, Croc then told Batman of all the assassins hire to kill him on Christmas eve, as Croc began to taunt him, Batman knocked him out and left him on the roof of the prison for Lieutenant Gordon and his officers.

After causing chaos through the prison, sending Commissioner Loeb to the execution chamber, and getting beaten by the Bat, Croc was placed back in the prison only to be broken out by The Joker later in a prison riot. Croc then finds and confronts Batman before being shot in the back of his bullet proof head by Gordon who orders him back to his cell. Croc then exclaimed "Screw this!" and left both Batman and Gordon alone. He was presumably locked back in his cell after the Joker's riot, it can also be assumed he was one of the many supervillains that were defeated by Batman during the events of Christmas Eve, that he was transferred to Arkham after being reopened by Quincy Sharp.

Arkham Asylum
Killer Croc makes his debut in the game quite early. You first see him when you are walking the Joker to his cell along with the Arkham guards. He steps out of an elevator, threatening the Batman when he smells him. He is then forced to keep walking because of his electric collar, which contains him. Later in the game, the player has to venture into Killer Croc`s lair, to get the antidote for the Titan poison. These plants only grow in the Killer Croc`s lair. He comes blasting out of the water, and then charges at the Batman. The player can force him away by throwing a batarang onto his electric collar. In the end, when the player is trying to escape Killer Croc`s lair, he comes charging at the Batman, who blows up the ground underneath him, so Killer Croc falls back into the deepest parts of his lair.

Character Bio
His profile in the videogame Batman: Arkham Asylum states:

Born with a rare mutation that made his skin green and scaly and grew his body to grotesque proportions, Waylon Jones was raised by an alcoholic aunt and bullied relentlessly for his appearance. He briefly worked as a carnival freak under the name Killer Croc, but his misanthropy grew as did his bestial nature, pushing him to a life of crime. As his physical condition and mental state deteriorate, Killer Croc becomes a more bestial foe, increasingly detached from humanity.

Batman Arkham City
"YOU ARE NOT WELCOME HERE!"

- Killer Croc

Killer Croc makes a very brief (and rather pointless) cameo in Batman Arkham City. After Batman defeats Ra's Al Ghul and gets a blood sample, he decides to leave Ra's hideout and give the blood to Mr. Freeze. While he's getting out of the sewers, Batman decided to throw one of his Remote Batarages at a certain button. When the button is hit, Killer Croc breaks through the wall. Instead of fighting Batman, Killer Croc said that he will die, and when that happens Croc would feed on his corpse.
