The story of Joe, a Ewing's Sarcoma patient who was invited to tour Riot through the Make-a-Wish Foundation. Riot then put Joe's favorite skin, Jaximus, on sale, with all proceeds going to Make-a-Wish. When Joe passed away, Jaximus got a unique new line. "Here's to you, kid!"
As a side note: Jaximus was almost put into the Legacy vault (basically, it could only be purchased whenever the vault opened), which lead to fans asking Riot not to put it into the vault. So, not only did Riot not put the skin in the vault, Jaximus is always registered as "Limited Availability" as a way to get people to look into the skin's origin and history.
Riot artist IronStylus was tasked with designing a female tank champion. He needed a strong woman to base her on... so he asked his wife to be the model. He later admitted Leona's default art is more or less an unaltered portrait of his wife, just with her hair and eyes colored orange.
Trials of the Poro, a short movie about one of the game's mascot Ridiculously Cute Critters getting caught up in a huge battle somewhere in Freljord while searching for Poro Snax. The heartwarming comes in when the terrified little poro is saved from an enormous Rain of Arrows by a huge, cheerful, bald warrior with a giant shield and a Badass Mustache (actually the first reveal of upcoming champion Braum) who, after saving him, arranges his fur into a little mustache of his own.
Braum: Next time, you get my back, eh?
Braum himself is essentially a Crowning Character of Heartwarming in many ways. Not only is he a Spirited Competitor and ultimately friendly to every other Champion in the league, but this carries over into gameplay as well - his entire kit is dedicated to protecting his teammates and shielding them from enemy attacks. You will feel good playing this Champion or being supported by him. His W skill, titled "Stand Behind Me," is often accompanied by lines such as "Stand behind Braum!" or "And you thought you were in trouble." His whole personality can be summed up in one of his movement quotes:
Braum: "Sometimes icy heart just needs warm smile."
Compounding this is his backstory/lore. What was that, you thought he'd be a Stepford Smiler with a tragic backstory to make him look like a Sad Clown? Well, NOPE. Braum's lore is basically just yet another his folk tales about saving other people. He's always a positive Nice Guy from get-go and has always been as such from start to finish. There's no such thing as angst in Braum, he's genuinely friendly, cheery, supportive. Sometimes, in the world where 'edgy is cool' and True Art Is Angsty, it's always assuring that there are guys like Braum, like saying that you don't have to be dark and edgy to be cool, and being a Nice Guy isn't that boring, but awesome.
Azir's reincarnation story. Sivir has just been betrayed by Cassiopeia (who in turn, becomes cursed herself, and released Renekton and Xerath back upon the world) and left for dead. What's Azir's first thoughts upon returning from the dead due to Sivir's blood (having unknowingly been descended of his bloodline) and actions? He picks her up and takes her to a place with healing waters, and brings her back from the brink of death. This selfless act, causes him to receive the power of Ascension, and begin the revival of Shurima.
The reason Lee allowed his fellow monks to stop his self-immolation? His sister, who was living in Galrin (which was one of several Noxian-occupied provinces at the time), visited him after Ionia was liberated.
After a mutual hostility that lasted years of real time, the former partners Twisted Fate and Graves have resolved their differences. They're even officially listed as "Friends" on their respective champion bios. (Though you'd better believe they had to earn that reconciliation.)
Japan and PC Gaming aren't exactly the most compatible pair, as the latter is mostly having cult favorite status in the former (console and mobile gaming are bigger hits there). But then, Riot Games revealed on how they are planning up the Japanese server, and they're really serious on this, not only they bring forth several well-known Names to Know in Anime, these seiyuus (so far Sumire Uesaka (Jinx), Keiji Fujiwara (Master Yi), Aoi Yuki (Lulu) and Natsuki Hanae (Ziggs)) truly gave their all for this job (FujiKei even claimed to have traveled to a mountain to meditate, solely to prepare himself to the role of Yi) and are enjoying the work with Riot, Hanae has also recalled that he's actually an avid LOL player and did a lot of Ranked Games, attended local tournaments and has nothing but enjoyment recalling those memories (in spite of being Japanese, he'd have to content with the massive lags, and with the release of LOL Japan, he and the rest of Japanese players may get a better, less laggy environment). It might be small, but it's nice to see that even LOL, confined in a platform not that widespread in the Land of the Rising Sun, are well loved there beyond just fanarts.
The climax of Lucian's story in Shadow and Fortune. Throughout the story, Lucian has been waiting for his chance to get revenge on Thresh for murdering his wife Senna, although he's increasingly troubled by how he's starting to find it difficult to remember her face without looking at the locket he wears with her picture in it. When he confronts Thresh, the wraith is immune to his weapons and gloats that he tore their secrets from Senna's mind when he enslaved her soul, horrifying Lucian and driving him to a Heroic B.S.O.D.. When Thresh is about to finish him and claim his soul, Senna herself forces her way to the front of the crowd of hundreds of thousands of tormented souls trapped in the lantern and implores him to fight and live. Wrapping his locket's chain around Thresh's wrist and stabbing him through it with his silver awl, Lucian weakens Thresh's control over the lantern and Senna leads the souls in rebellion against the Warden, weakening his defences enough for Lucian to blast him with their twin relic weapons, forcing him to flee for his unlife. The Power of Love triumphs over the darkness and Lucian finds a new purpose in life beyond simple revenge- to finally free Senna from Thresh forever.
He caught the briefest glimpse of Senna’s face in the lantern and etched it on his heart.
Never again would her face grow dim in his memories.
[...] “Thank you, my love,” said Lucian. “My light.”
In a sense, Kled's reveal video Reunion has a rather heartwarming touch, the reunion between him and Skaarl gives off a feeling as if someone found their lost pet, or reunited with an old friend. The big smiles on both of their faces sold the fact easily. The Stinger soon after gives off a feeling of doing something fun the two would always do before the separation.
This is also expanded upon in his lore's short story, "Where the Drakalops Roam". After Kled finds himself nearing death while fighting against Noxian Soldiers, Skaarl seemingly shows up by his side in the nick of time, ready to fight after having ran off prior in the story.
Kled: Any hope I got of surviving this, it’s gone… And that’s when I see her. The most loyal, trustworthy, honorable friend an undeserving bastard like me could ever have. Skaarl.
Riding like hell toward me. Faster than I’ve ever seen her run. A rooster tail of dust is shooting up behind her. The damn lizard even picks up my hat on her way to me. I run to her just as those black-clad warriors are about to crush me. I leap into the saddle, and we circle around the iron warriors. There’ll be time to kill them after we get rid of that ballista.
Like many other champions, Ahri gets her own Arcade skin. In the official splash art◊, bottom right corner, Ahri has her health bar completed with a chibi 8-bit eye shut icon of her. The in-game back to base animation has her happily hugging an old arcade machine and proceeds to play it.
Xayah: If things go wrong— Rakan: They always go wrong. Xayah: They don't always go wrong. Rakan: Mostly? Xayah: They mostly go wrong. Rakan: That's why I'm here.
Rakan: Did I tell you I love you? Xayah: Yes... but say it anyway. Rakan: I love you.
Xayah: I'm so tired... Rakan: You gotta rest, honey. Xayah: Everyone is depending on me. Rakan: Everyone can wait.
Rakan: What would you do if I died? Xayah: I would... burn this world to the ground and build a castle from the ashes, where I would live alone forever. Rakan: Aw... that's sweet.
Xayah: I swear, you will be the death of me. Rakan: I'm fine with that. Xayah: Me too.
Mixed with , the story of Doran, creator of Doran's Ring, Shield, and Blade. He was born with a passion for crafting, and at the age of 15, he became an Ultimate Blacksmith who got invited to the Institute to be their blacksmith. However, on route, he suffered an accident that robbed him of his genius, but not his passion, and where once he produced single, masterpiece items, he now produces simpler items in large quantities. The fact that his items are daily used in matches, and he has a permanent home at the Institute, shows that, even if bittersweet, he still got a happy ending.
It's a very subtle feeling, but when one goes about having Ornn forge an item himself, you can just about hear the contentment in the light humming he partakes in while he works. It makes it clear that while Ornn may be a grumpy old goat away from his forge, he loves his hobby. He loves creating. And that he can enjoy making anything like that, even in the middle of a battle, is pretty sweet.
Reginald: Fear of Failure features Team Solomid's captain Andy "Reginald" Dinh and his tale of going from a troubled schoolkid to the leader of one of America's biggest teams. It's really inspiring and almost goes into Tear Jerker in a few parts.
"There's always gonna be that bad guy, and I don't mind being it."
Who says that even fandom can't make a heartwarming story, even if it's probably non-canon? Take a look at She Who Is Like A Sun To Me, which takes Pantheon's baker joke and Leona's protective instinct into a story of sweet friendship that may shed a lot more humanity on the war-worshipping Rakkor warrior, and launch the Pantheon/Leona ship even further. note The summary: Pantheon used to be a ostracized Rakkor kid because of his baking hobby, with everyone else bullying him for that, and only Leona staying as his friend, driving away the bullies and enjoying his cakes. Even as he became the paragon of Rakkor and their way of warrior, and Leona became a member of the Solari, Pantheon will always see her in high regard.
And if you look at the comments of the link... it looks like IronStylus loves this one.
Well speaking of Blitzcrank/Orianna, you may want to check out this short story Deus Ex Machina which involves some Tear Jerker, some Moment of Awesome, but most importantly, lots of feels for the two. Guest starring Viktor.
A player on EUW befriended a person who happened to suffer from severe depression through League, and supported him for months. One day, when his friend said that he was going to quit League and kill himself, this player went and made a Reddit thread talking about the issue and pleaded for help from the community to help find him and possibly notify the authorities. Hundreds of people commented, talking about their own history of depression, expressing concern for this suicidal friend, wishing him luck and praising him for what he was doing. One Redditor even managed to reach Riot Deficio and ask him for help. Eventually, the player's friend came back online and explained that he was alright. While the post may not have served much of a purpose in the long run, it goes to show how a community that is branded one of the most toxic communities known to man will still take its time and effort to help and support someone in need.
