HBO Max’s new series Lanterns has reignited interest in the cosmic reaches of the DC Universe, drawing viewers back to the Green Lantern Corps and its sprawling galactic mythology. But one particular storyline beat from the show’s first season has also resurfaced a beloved internet joke that has been circulating for two decades: the Hal Jordan Head Injury Project.
The series, which premiered in early 2025, follows the adventures of Green Lanterns patrolling the outer edges of known space. Its debut episode featured a nod to Mogo, the planet-sized member of the Corps, while also leaning into its protagonist’s tendency to spend much of his screen time unconscious. That choice landed just weeks before the twentieth anniversary of one of comic book fandom’s longest-running gags.
A Reference That Lands for Longtime Fans
The first episode of Lanterns packed in a great deal of DC lore, from feuding alien factions to killer robots and a colossal wall constructed from dead gods that marks the far boundary of existence. Notably, it remembered to include the planet-sized Green Lantern Mogo among its cosmic cast.
Yet perhaps the most essential element of the entire Green Lantern mythos made its way onto the screen in an unexpected form: protagonist Hal Jordan spends a considerable amount of time knocked out cold. For casual viewers this may pass unnoticed, but for those familiar with DC’s comic history, it serves as a fitting tribute to a running joke that has endured since the early days of online fandom.
The Head Injury Project Explained
Through sheer coincidence, Lanterns debuted about a month after the twenty-year anniversary of one of the internet comic book community’s longest-running gags. More surprisingly, thanks to the inexplicable immortality of both Flickr and Blogspot accounts, most of the Hal Jordan Head Injury Project remains online today.
The project is a tongue-in-cheek tracker tallying the sheer number of times that Hal Jordan has taken a blow to the head throughout his nearly seventy-year history as a character.
Sleestak, creator of the Head Injury Project
Put together by an internet figure known simply as Sleestak, who still blogs occasionally at Lady, That’s My Skull, the project catalogs every instance in which Hal Jordan has been knocked unconscious. To be fair, any long-running superhero has likely been knocked out on multiple occasions and under ridiculous circumstances. Spider-Man, for example, has been struck by his Aunt May with a vase more times than anyone can count.
The difference lies in how frequently it happens to Hal. Unlike many of his superheroic contemporaries, Hal Jordan was traditionally depicted as a reckless maniac for much of his existence as a character, exactly the way he is portrayed in Lanterns. He typically charges head-first into situations with a zeal and lack of foresight usually reserved for heroes endowed with healing factors or suicidal tendencies. Especially during the Silver Age, or in stories featuring a younger Hal, he caught a disproportionate number of straight chin checks.
The Best Cases That Never Made The Archive
One of the most striking aspects of the project is that two of the greatest Hal Jordan skull cracks are not currently preserved in its archive. One of the best examples that does survive comes from a particularly wild Silver Age story titled Crisis in Triplicate.
In that tale, the Justice Society and Justice League have been mind-controlled by demons into fighting the Legion of Super-Heroes. At one point, the Legion’s telepath Saturn Girl uses her powers to force Hal to punch himself out. It is not a knockout blow—Black Canary defeats Saturn Girl three panels later—but it remains a useful visual metaphor for how Hal Jordan has historically been his own worst enemy.
Another memorable entry comes from Green Lantern: Emerald Dawn, a six-issue limited series published in 1989. In the wake of Crisis on Infinite Earths, the DC Universe received a full reboot, and Emerald Dawn served as a deck-clearing exercise to establish Hal Jordan’s origins within this new continuity.
The first issue, written by Jim Owsley—now known as Christopher Priest—with art by M.D. Bright, follows a young Hal Jordan following in his father’s footsteps as a test pilot. When Hal attempts to drive home drunk, he rolls his car, ending up in the hospital and badly injuring his brother Andy. Still fuzzy from head trauma, he is then chosen by Abin Sur to become Earth’s first official Green Lantern, and he does not take the news well.
The sequence explains why Hal chooses to blame a random road sign rather than his own poor decisions, and why his attempt to destroy that sign ends with him flat on the ground. Canonically, post-Crisis Hal Jordan’s very first superhero fight was against an ordinary billboard—and he lost.
A Modern Legacy
The final example traces back to Justice League of America volume 1, issue 110, published in 1974 by Len Wein, Dick Dillin, and Dick Giordano. It is the issue in which John Stewart first joined the team, having been introduced as Hal’s official substitute within the Corps.
Batman and Superman attempt to assemble the team after the Christmas Eve murder of an actor playing Santa Claus. A note and key found near the body suggest that if they cannot find the matching door before midnight, a bomb will detonate and destroy a city block. Unfortunately for Hal, the JLA signal fires just as he is stepping into the shower. Distracted, he slips on a bar of soap and knocks himself unconscious. His ring answers the call in his stead, running off to fetch John while Hal remains sprawled across his bathroom floor.
Hal is not quite as prone to being knocked out in modern DC stories, where the ring has become less fallible and there are fewer opportunities for him to be felled by random thugs. Nonetheless, whenever someone punches a superhero in the back of the head, Hal Jordan and his namesake project remain present in spirit—a fitting reminder that Lanterns is only the latest medium to capture the enduring charm of its most bumbling hero.
