Ben Schulz created the Leeroy Jenkins character while playing World of Warcraft with his college friends in the guild "Pals for Life"4. The original video, titled "Leeroy!!," was uploaded to Warcraftmovies.com on May 11, 20053. The guild posted the video to the official World of Warcraft forums under the thread title "UBRS (vid) Rookery Overpowered! blue plz." and asked other players for help with strategy, framing the clip in a serious context5.

Schulz later explained in a 2008 NPR interview that the players "were drinking 40s and just yelling at each other" during the recording5. The video was filmed by Ben "Anfrony" Vinson, a friend who would later co-confirm the clip's true nature4.

The question of whether it was real dogged the video for over a decade. Schulz preferred letting viewers decide for themselves4. Then in December 2017, Schulz and Vinson released what they called a "first take" or dry run, confirming the video was staged. Vinson said, "We didn't think anyone would believe it was real, we thought it was so obviously satire"5.

Few gaming memes have crossed into as many non-gaming contexts. The video earned a Jeopardy! question, putting World of Warcraft terminology on network television game shows4. The Guardian's 2006 machinima feature used Leeroy Jenkins as its primary example of gaming video crossing into mainstream awareness2.

The meme's reach into American politics is striking. Jon Stewart used it on The Daily Show in 20125. A military journal published an academic analysis connecting Leeroy's behavior to American foreign policy strategy5. Two different political commentators referenced it during significant political moments in 2019 and 20235.

Blizzard's decision to canonize Leeroy within their own games was unusual for the time. The character went from community joke to official trading card to in-game NPC to Hearthstone Legendary, a progression that turned a player-created moment into permanent game lore5.

The video's path from gaming in-joke to mainstream fixture happened in distinct phases. In the first few months after the May 2005 upload, it circulated primarily within the World of Warcraft community. The guild posted the video to Blizzard's official forums framed as a genuine gameplay discussion, which added to its appeal. The thread was edited multiple times to add download links as demand grew, indicating the video was being shared widely across fan sites before any major video platform picked it up4.

The shift to mainstream awareness started with the YouTube era. While the first YouTube upload in late 2005 didn't immediately catch fire, the August 2006 re-upload aligned with YouTube's rapid growth period and racked up tens of millions of views4. By then, PC Gamer UK had already published its analysis arguing Leeroy was actually the hero of the video, acting against the "geekiness" of his guild's fastidious planning5.

Schulz's personal trajectory after going viral was unusual for an early internet celebrity. Global Gaming League reached out and invited him to attend BlizzCon in 20064. He was invited to speak at ROFLCon for three years before finally giving the keynote speech at the event in 20084. Multiple video game companies contacted him asking if he could recreate the video's success. He turned them all down, choosing instead to finish his college education and become an electrical engineer4.

At ROFLCon III, Schulz shared that he had stopped playing World of Warcraft after the Frozen Throne expansion, returned briefly during Cataclysm, then cancelled his account for good. He noted that he was still an active gamer on Kongregate, a platform founded by Ben Vinson, who had filmed the original Leeroy Jenkins video4.

Blizzard's relationship with the meme evolved from acknowledgment to full embrace. The company added an achievement called "Leeeeeeeeeeeeeroy!" in 2008, awarding the title "Jenkins" to players who killed 50 rookery whelps within 15 seconds5. A Leeroy Jenkins trading card appeared in the World of Warcraft Trading Card Game on October 25, 2006, illustrated by Mike Krahulik of Penny Arcade15. A miniature figurine followed in Upper Deck Entertainment's World of Warcraft Miniatures game in fall 20085. Leeroy was added to Hearthstone as a Legendary card using the same Penny Arcade art5, and in March 2022 debuted as a playable mercenary in Hearthstone's Mercenaries mode5. In 2024, Blizzard held an Overwatch 2 and World of Warcraft crossover that added two Leeroy-themed voice lines to the character Torbjörn, including him shouting his own name in Leeroy's style and saying "at least I have chicken"5.

The meme's political afterlife is notable. In 2009, Captain Robert M. Chamberlain wrote an article in the Armed Forces Journal titled "Let's Do This!: Leeroy Jenkins and the American Way of Advising," connecting the meme to the American approach to advising Iraqi armed forces5. Ben Shapiro compared Donald Trump to Leeroy Jenkins in a 2019 episode of his show5. During the prolonged Speaker of the House vote in January 2023, Representative Jared Huffman referenced the meme while casting his vote for Hakeem Jeffries5. IGN placed Jenkins 10th on their 2017 list of best Blizzard characters, noting he represented the rare crossing of a line between a game's content and its community5.

The December 2017 revelation that the video was staged barely dented its cultural standing. By that point, the clip had been referenced so widely that its authenticity was almost beside the point. The character had already been canonized within World of Warcraft itself as an NPC, and the catchphrase had entered everyday language as shorthand for reckless action4.
