The Joker (LEGO Batman: The Videogame)

The Joker is a Batman villain that appeared in LEGO Batman: The Videogame. He was once a petty criminal who fell into a vat of chemicals. The toxic brew turned his skin white, his hair green, and his lips red, giving him the appearance of a crazed clown. Taking the alias of "the Joker," he henceforth started executing schemes that involve both jokes and puns.

LEGO Batman: The Videogame
After orchestrating the breakout at Arkham Asylum, he becomes one of the three main villains that form a group of inmates to perform crimes. He, along with Harley Quinn, Scarecrow, and Mad Hatter, plan to detonate several bombs in Gotham Cathderal and cover Gotham in Joker Gas. He first goes to a chemical factory with Mad Hatter to create his Joker Gas. Next, he and Harley Quinn capture Commissioner Gordon to lure Batman and Robin to circus and attempt to defeat them. He and Scarecrow, then engage the Dynamic Duo in a mid-air battle, in which both villains crash their planes into the Gotham Art Gallery. Joker and Killer Moth then move towards the Cathederal to prepare the bombs, but Joker later dispatches Killer Moth to delay Batman and Robin when they begin to catch up to them. He and Quinn then arrive at the Cathederal and set up the deadly bombs. Batman and Robin thwart him, but in a last ditch attempt, he attacks the Duo with his joy buzzer, knocking them out. As he moves in for the kill, Batman strikes a bell, full of bats, causing the bats to attack Joker and Quinn, disorientating them as Commissioner Gordon and the police arrive at the scene. He is last seen in his cell at Arkham. Angry at his defeat, he pulls a gun out and holds it to his head. He pulls the trigger, and a "Boom" Flag shoots out, causing the Joker to laugh hysterically.
