This is a work in progress
League of Legends has over 800skins and some of them share the same universe. It is possible to conclude that 2 skins share the same universe via splash arts, promotional material (like websites, videos, images, stories), in-game quotes and in-client Skin Set's Universe. Keep in mind that some of the skins listed here as "sharing the same universe" might actually not share. Easter eggs are just that, easter eggs.

A legendary wilderness archer, Ashe is the first and last member of the Woad Tribe many a wayward traveler will ever meet. Nothing is known of her past, save for frozen corpses littering the northern trails.
For a Woad tribesman to be named king, they must venture alone into the den of a glacial hydra and return with one of its heads. Darius, it is said, came back with all nine.
Pity those poor souls lost in the northern mountains—Quinn, scout of the Woad Tribe, will always find them. And those who cross her path are said never to return.

Boy-king of the southern wastes, Amumu's mummified body still haunts the halls of his ancient tomb. His mournful sobbing can be heard over the brutal desert winds, luring in unwitting adventurers.
Immortal beast of the northern lands, Nasus wanders the expanse of the Great Desert in search of his once-green kingdom. He conjures vast sandstorms to cover his tracks, hiding his existence from the world.
At the height of her power, Nidalee was worshipped as a god-queen of the Great Desert. After her city's fall, she gathered her remaining armies and marched west, to conquer and rule anew.

Steel Valkyries is a set under the Universe category on the client.
- A galaxy scarred by war now attempts to rebuild, but the old wounds remain. Criminals, bounty hunters, mercenaries, and assassins have filled the power vacuum, piloting dangerous combat exo-suits with godlike abilities.
Formerly a frontline general in the now-disbanded Confederate Alliance, Darius once scoured the surfaces of entire planets in bitter campaigns against the RSM. Left devoid of purpose at the close of the war, the Dreadnova Corps offered him a chance to lead—and fight—again.
Once a high ranking admiral in the Royal Space Military, Gangplank's reign of terror began when he stole and proliferated blueprints for a former colleague's experimental superweapon. Ending a thousand-year civil war in an instant, he defected with a massive armed battalion and formed the interplanetary criminal network known as the Dreadnova Corps.
A former lieutenant in the Royal Space Military, Kai'Sa was the first sanctioned pilot of the experimental X01-Butterfly. The suit proved far too deadly, however, and after only one mission she fled with the technology—becoming one of the galaxy's deadliest guns for hire.
Sarah Fortune is a living weapon of mass destruction; a legendary bounty hunter seeking revenge among a galaxy of thieves. Shot and left for dead, she now pilots the deadliest combat exo-suit in known space—and she'll stop at nothing to bring violent justice to her would-be killers.

Luchador is a set under the Universe category on the client.
A contemporary wrestler beloved the world over, El Tigre's roar is the bellow of a people's champion. He is a friend to all but can still scissor kick a two hundred pound cage fighter right out of the ring.
Probably in a position he'd rather not be in, El Macho will be facing down three of the greatest fighters in modern history for Sunday's no-holds-barred money match. Luckily for him, Mundo has more madness to offer than the federation think he's got, and the cream always rises to the top.
He's big. He's small. He's throwing pieces of the ring around like it's made of pixie dust and unicorn whispers. He's El Leon, the eighth wonder of the world, and he's here to say to his opponents.
The Wrestling Federation of Valoran would like to put these terrible rumors about our beloved El Rayo to bed once and for all. One: he is definitely a bear, and not a man dressed as a bear, as some might claim. Two: bears make amazing wrestlers.

Arcade is a set under the Universe category on the client. It is divided into Arcade: Heroes and Arcade: Battle Bosses. Arcade has had various promotional materials including websites, videos and images all connecting the various skins and confirming a shared universe.
Owner of the mysterious six-million-point high score in the infamously difficult beat-em-up Demacia Vice, Ahri is a force of nature on the retro battlefields of Arcade World. Dashing between bosses before ripping them apart with her 8-bit magic, she's already earned the nickname “Queen of the Arcade.”
The fearless protagonist of a 1980s top-down shooter, Corki resists Veigar's battle bosses the same way he resists being shot down by thousands of glowing bullets—move fast, and shoot everything before it shoots him.
A skilled gamer transported to Arcade World by Veigar, Ezreal holds the world record for speedrunning the original version of Hyper Crystal Dungeon in 45 seconds, using a custom-made mobile controller. Veigar has made a terrible mistake.
An unlikely favorite among retro purists, Hecarim has remained one of the most popular characters of the arcade era. Now he stands against the combined forces of gaming's greatest villains, proving there's no hero more noble than a rainbow-shooting chrome centaur from 1978.
Miss Fortune (Sarah to her friends) is better known in the real world for holding the top scores in every shoot-em-up game ever created. In Arcade World, she's famed for earning those scores through whatever means necessary, willing to bring in any target for the right amount of points.
Riven's part-time job at an arcade mostly involved playing dance simulators after her manager went home. Digitally transported to Arcade World by even scarier bosses, she's now using her moves (and some gear from her favorite RPG) to tear up Veigar's regime, one enemy at a time.
Being forcefully transported from the real world to fight an army of evil video game bosses is no sweat for Sona. She was the first person to beat Keyboard Solo 4's ultra solo mode on nightmare difficulty—a feat that, by the developers' own admission, should not have been possible.
A boss hailing from a popular science fiction shooter, Blitzcrank is well known in the gaming community for cheap mechanics, powerful attacks, and a massive health pool. Veigar fittingly made him the gatekeeper of his personal fortress, because Veigar hates fun.
The fire boss from a bestselling action game, Brand has no intention of returning to his original machine. He'd rather see all of Arcade World burn to the ground, to be rebuilt in the image of the villains who rule it.
A boss hailing from a long-forgotten game cabinet, Malzahar broke free from the last remaining copy of his game to invade nearby machines. Now he has made his way to Arcade World, shredding the code of his enemies with an army of intelligent viruses.
Once merely a mini-boss with a Napoleon complex, Veigar has ripped into the code of Arcade World to summon hundreds of other bosses to his side. Together they'll stop at nothing to reach his ultimate goal: take the world for himself, and give the heroes a final Game Over.
A boss originally from Super Yordle Bombers, Ziggs was transported to Arcade World for one purpose: blow up everything. Armed with his signature explosives (and the programming to use them!) he has wrought digital destruction the way only an angry mini-boss can.
Debonair is a set under the Universe category on the client. Debonair has had various promos including a image of a fake magazine with Jayce on the cover and images of the four skins in-game. The setting of each splash art seems to be the same and the same type of casino coins can be seen in all splashes (excluding Jayce's).
Tailored suits, fitted vests, and an elegant gauntlet let everyone know the difference between Ezreal and the common rabble is simple. He makes this look good, and they don't.
Savor that elixir. Highlight that heavenly white tux with a royal purple reserved for kings and queens who just don't deserve it. Because when you're an eighty foot tall petricite gargoyle, you're always the center of attention.
You're a scholar. You're an inventor. You're the man of the hour and the hour is now, yesterday, and tomorrow. Don't just be the father of invention-be the ivory god of substance, class, and style. It's you, Jayce. It's always been you.
Don the yellow power tie and red rose boutonnière of a woman in charge-of herself, her destiny, and the two dozen spines she's going to snap in effortless, elegant style.
All Esports team-related skins have their own Universe category on the client. These include Fnatic, SKT T1, SSW and TPA.

Speculation[]
- Galactic Azir might be part of the same universe as Galactic Nasus and Galactic Renekton due to the canon lore shared between them.
- Kennen M.D. might be part of the same universe as Nurse Akali and Surgeon Shen due to the canon lore shared between them.
- Both Kennen M.D. and Amumu were considered to be part of Nurse Akali's splashart.
- Both
- Augmented Singed could be part of the Bioforge/ Steel Legion universe due to the similarities between Singed and Darius, as well as the fact that Bioforge is a "pact between Noxus and Zaun".
- In Riot Blitzcrank's splash he is seen shielding himself from shots similar to Hired Gun Lucian's.
Notes[]
- Despite being part of the "Riot" category, Riot Girl Tristana is most likely not part of the same universe as the other Riot skins.
