Knowledge Waits is a feature where I just share some bit of comic book history that interests me.

My pal Sue, of the wonderful site, DC Women Kicking Ass, was wondering if there was a collection of all of the times that there were references made to the famous "One Punch" moment involving Batman and Guy Gardner from Keith Giffen, J.M. DeMatteis, Kevin Maguire and Terry Austin. Inadvertent challenge accepted, Sue!

Okay, so the classic moment originated in Justice League #5 (by the aforementioned creative team), when Guy Gardner had been ragging on Batman for the previous four issues, talking about how GUY should be the leader of the team and not Batman, even though everyone else (Batman included) assume that Batman is the leader.

Finally, Guy went too far and Batman agreed to fight him and, well, it did not go well for Guy...

It became such an iconic moment that Gerard Jones, M.D. Bright and Romeo Tanghal addressed it in Green Lantern #25, when Hal asks Guy to give him back his old Sector and Guy says no, so they fist fight for it.

It looks like it might be "one punch" time again...

But Guy is NOT going down like that this time...

In the end, Hal takes a brutal beating but he tires Guy out and gets his sector back. Part of the fight involved the loser leaving the Green Lantern Corps, so Guy left.

In 2001's Batman Beyond #22 (by Hilary Bader, Rick Burchett and Dan Davis), Batman of the future punches out the Green Lantern of the future. I'm not POSITIVE this is a one punch reference, but I figured I should include it to be safe...

When Hal Jordan returned as Green Lantern in Green Lantern: Rebirth, Batman was not happy, and Hal expressed his feelings about Batman's feelings in Green Lantern: Rebirth #6 (by Geoff Johns, Ethan Van Sciver and Prentiss Rollins)...

This then led to a follow-up in Green Lantern #9 (same creative team). The first time had a specific "one punch" reference that this one was lacking, but eh, I think it still counts because it is a clear follow-up to the previous one. Otherwise, I am not counting every time a superhero gets knocked out in one punch. That way lies madness.

In Justice League of America #0 (by Brad Meltzer and, on this page, Kevin Maguire), we see a flashback to Batman telling Superman and Wonder Woman about the incident...

In the Brave and the Bold cartoon, "Eyes of Despero," Batman knocks out Guy, with G'Nort now being the one who says, "One punch!"

In a later episode, "Death Race to Oblivion," Batman knocks out Mongul with one punch and Guy mocks Mongul for being knocked out in one punch ("Ya mook!")...

In the final issue of Guy's solo book, Green Lantern: Emerald Warriors #13 (by Peter Tomasi, Ron Frenz, John Dell and Marc Deering), Batman and Guy team up and Guy gets to admire Batman "one punching" someone else...

In Geoff Johns' final issue of Green Lantern (Green Lantern #20), we see a glimpse of the future and Guy is an old man, but can still knock people down with one punch...

In Superman/Wonder Woman #2 (by Charles Soule, Tony Daniel and Matt Banning), Apollo seemingly takes out Superman with one punch...

In Injustice Year Three #4 (by Tom Taylor and Mike Miller), Batman takes his frustrations out on John Constantine with one punch...

In Red Lanterns Annual #1 (by Charles Soule and Miguel Sepulveda), the Red Lanterns are on Earth and Guy needs Batman to trust him and their "one punch" history is mentioned...

In Convergence: Green Lantern Corps #2 (by David Gallaher, Steve Ellis and Ande Parks), there is a quick reference at the end (in a story that spotlights Guy finally getting his ring in his universe)...

Finally, in Green Lanterns #23-24 (both written by Sam Humphries and drawn by Eduardo Pansica and Julio Ferreira in the first issue and Carlo Barberi and Matt Santorelli in the second issue), Guy is training Jessica Cruz and she responds by punching him...

but Guy explains that it takes more than one punch to take him down, no matter what Batman might say...

I believe that takes us current.

Again, we're not counting every time that a superhero knocks out another superhero, not unless someone actually says, "One punch!" or, like the Injustice scene, it's a direct homage.
