Leeroy Jenkins is a player character created by Ben Schulz in Blizzard Entertainment's multiplayer online video game World of Warcraft.

[2] The video features a group of players discussing a detailed battle plan for their next encounter while Leeroy is away from his computer, preparing a plate of chicken.

Aliens[20][21] and appearances in video games not developed or published by Blizzard, such as Mass Effect.
