Wikipedia Draft:KFC one-shots

Between 2015 and 2017, DC comics, in partnership with fast-food restaurant KFC published three short one-shot comic books – The Colonel of Two Worlds, Colonel Corps, and Across the Universe, each featuring KFC mascot Colonel Sanders working with popular DC superheroes such as Green Lantern and Flash. Originally exclusively available at various comic cons, they were later made available for free download by DC.

The Colonel of Two Worlds
Kentucky Fried Chicken Presents: The Colonel of Two Worlds was given away free at the 2015 New York Comic Con.

Plot
Colonel Sunder (Colonel Sanders' evil twin from Earth-3) teams up with Mirror Master and Captain Cold, and starts his own rival to KFC, named 'Easy Fried Chicken'. At the same time, he hires a team of henchmen to rob banks so that he can quickly open new franchises without doing any work (irritating Rogues Mirror Master and Captain Cold who have more ambitious plans). Annoyed at Sunder "carpetbaggin'" his public image, Sanders heads to Easy Fried Chicken, accompanied by Green Lantern and Flash, where he defeats Sunder’s henchmen, and throws Sunder back through a portal to Earth-3. Mirror Master and Captain Cold decline to get involved ("You’re not worth it, Sunder") and work off their debt to society at KFC.

Colonel Corps: Crisis of Infinite Colonels
Kentucky Fried Chicken Presents: The Colonel Corps was given away free at the 2016 New York Comic Con.

Plot
Furious at Colonel Sanders constantly beating him, Sunder hires a new "partner". Colonel Sanders, on Earth-1 suffers a sudden blackout, and upon waking, is greeted by Colonel Arla Sanders from Earth-11 and that world's Flash, with her cosmic treadmill. Arla explains that Sunder ambushed her, causing her, like Sanders, to forget the Secret Recipe. He is then taken on the ride of his life as they go try rebuild the famous recipe that has all but vanished from their minds and that of the Colonels of other universes: Comrade Sanders (Earth-30), Teen Colonel (Teen Titans Go! universe), Bizzaro-Sanders (Earth-29), Koln-El (Earth-22), Kolonel (a chicken, from Earth-51), Detective Colonel "Hardcase" Harland Sanders (Earth-19), Cowboy Sanders (Earth-18), All-Star Colonel (Earth-2), and Colonel Lad (31st century Earth).

Once gathered, the Colonel Corps head to Earth-3 to take on Colonel Sunder (the Anti-Colonel) and his new partner, Colonel Grodd (a Colonel version of Gorilla Grodd, possibly from Earth-52), who have returned to the Multiverse. A swift battle ensues, and Sunder once again learns that the easy way does not pay.

Across the Universe
Green Lantern co-starring Colonel Sanders (also known as Across the Universe) was given away free at the 2017 San Diego Comic Con.

Plot
A satellite containing a Zinger crash lands at Ferris Aerospace. The Colonel rescues the burger, and, in front of press, reveals that he is going to make the Zinger "universally famous". He enlists Hal Jordan’s help, with the Green Lantern Corps opening warp gates to send the Zingers to hundreds of worlds. However, upon arrival at their destinations, the containers all turn out to be empty. Investigating, Hal Jordan makes a copy of his ring for Harland Sanders. The duo then head to the source wall, then to planets Rann and Thanagar, where Adam Strange and Hawkgirl give them clues which allow them to deduce the thief: Larfleeze. After a short battle, the Colonel gives Larfleeze franchise rights so that he can use his orange energy constructs to make himself all the Zingers he wants. In recognition of his work containing the threat of the Orange Lantern, the Guardians of the Universe make Sanders an honorary Green Lantern.
