Ash Ketchum in Pokémon is known for loving any and all Pokémon, and this is not lost on them, as legendaries are drawn to him consistently. Even when Meowth fake-joins the team and betrays them, Ash states he will treasure the time they spent together.
Red accepts old foes (that tried to kill him) through Enemy Mine situations a little too easily. His All Loving-ness is most prevalent in the FLRG arc, where he readily accepts Deoxys since it shares his blood, even though it nearly massacred his team. He is the aforementioned Ash's counterpart, after all.
Dia calls out Cyrus for trying to destroy all of existence with a simple yet very heartfelt speech, Dialga and Palkia decide that they'd rather listen to him than Cyrus and earlier his own courage inspired Regigigas to fight Team Galactic as his teammate! His actions are so moving that they convince Cyrushimself that the world was a beautiful thing as it is, provoking a Heel Face Turn. This incredible feat is shared by the below-mentioned Hareta (who admittedly is his AU Counterpart).
Amuro Ray in Mobile Suit Gundam: Char's Counterattack sacrifices himself to save people from an asteroid and show them "the light" helping them to gain hope. Lampshaded in the video game Gundam Dynasty Warriors 2 where Amuro claims he is "no Messiah" before this storyline. His rival, Char Aznable, is a Dark Messiah in the film.
Rurouni Kenshin's titular character is known for helping others and avoiding massacres. A friend of his thinks in one scene that he will save his life even if Kenshin didn't want his help since there are several people in Japan who need him. Ironically, most of Kenshin's rivals tend to be Dark Messiah.
Shinya from Watashi No Messiah-sama accepts his duty to save the planet of his beloved by defeating the Big Bad, but refuses to harm anyone, including the Big Badeven after having ripped his heart off and left off to die. Earlier in the series he fires a lightning at himself to make Hime, who was trying to kill him, to back off without harming her.
Tohru Honda from Fruits Basket. Kind to everyone, forgives even the most evil, saves everyone with her love.
Their counterparts from the Nanto Roku Seiken; Rei, the Star of Justice, who must live and die for others, and his best friend Shu, the Star of Benevolence, who sacrifices himself for the sake of one hundred innocents.
Before her initial murder, Kikyo served the village by repelling demons and illness and she was kind to everyone, including rude half demons that tried to steal the Sacred Jewel; both Inuyasha and Naraku. Even after being revived from the dead, she is frequently seen helping weak and helpless people, although her personality undergoessignificant change.
Kagome. As the reincarnation of Kikyou, she has the Jewel of Shikon sealed inside her, and once she comes into Inuyasha's era she tries to help all the people she can while searching for the Shikon shards. A great example is her interaction with the very angry Cute Ghost Girl Mayu, who died in a fire and is full of anger and pain at her grieving mother; Kagome singlehandedly turns Mayu back to the side of good and saves her from Hell. She even saves Kikyou's soul from her dark fate.
When Orihime's captured by the Arrancar, she refuses to hurt them, shows them love and heals those who torture and abuse her. In the Nestle to Night novel, it's confirmed that the reason Harribel and her fraccions are still alive is because Orihime healed them. When she steps between Shishigawara and Tsukishima, Tsukishima notes her reputation and admits he's not surprised to see her trying to protect a man who had just threatened to kill her. However, he turns out to be wrong; she was trying to maintain Tsukishima's attention so she could confirm whether or not he was the person who had almost killed Uryuu.
Ichigo once made a vow to himself to never let anyone suffer a sad face the way he did when his mother died. As a result, he'll protect anyone who needs protecting, no matter how well he knows them or even if they're supposed to be on the enemy's side. The need to protect is the main driving force for his resolve. In the Lost Agent Arc, the villain's plan was to isolate Ichigo from being able to protect everyone in such a way as to cause his resolve to collapse utterly. The end result was a Darkest Hour that required Soul Society to step in and save not just his life but his entire sense of self.
Naruto himself, to the point where it makes you wonder why he had such an abnormally hard time making friends prior to the start of the series. Hinata, Shikamaru, Temari, Neji, and Gaara all note that he has the power to influence people. It's worth noting that Naruto tends to get off to a bad start with most of the people he befriends, and they're often completely dismissive of him for reasons typically unrelated to him having the fox inside him. Unlike many of the other examples, he's not always civil in response, but his determination and honesty cause many of these people to see him, and often themselves, in a new light.
Kakashi: Naruto has a mysterious power. Everyone who meets him becomes his friend, no matter how little contact they have beforehand.
This trope is so very prevalent that pretty much every single For Want of a Nail fanfiction gets him a fresh start to life because someone looks at him without bias for upwards of five, maybe even six, seconds. Another major recurring theme where this happens when Naruto is younger is him never thinking ill of the people around him, despite their indifference, hatred, and harsh treatment of him.
Hashirama Senju, the First Hokage, counts as well. Even as a child, his fondest wish was to bring an end to the constant fighting and dying that plagued the world by forming villages where kids could learn and grow instead of being slaughtered on the battlefield. When he was head of the Senju Clan, he was constantly trying to convince the Uchiha Clan to stop the fighting and join him, eventually succeeding. When he and the other previous Hokage are brought back with Edo Tensei for Sasuke to question, Hashirama immediately realizes that Sasuke needs help, and proceeds to sit the boy down and talk to him. He ends up proving his status by succeeding where Naruto failed: with mere words and wisdom, he convinces Sasuke to pull a Heel-Face Turn. Dude earned his Hokage credentials, that's for sure.
Vash often has to be prodded into shooting the bad guys instead of trying to reason the virtues of life with them. Even then, he refuses to kill humans, even if it means bandaging up the people he just took down. Wolfwood occasionally seems to see Vash in this light, and well beyond his Technical Pacifist stance above he will do anything to save people. From diving into blows that carved the scars all over him to stripping naked and barking like a dog to get a hostage free to training constantly so that his skills are up to pulling off his signature miracles. His whole identity is tied up in saving people. Finally, he's the primary defender of the human race on his planet, and main proponent of the creed that everybody can theoretically live in harmony. Even his True Companions aren't a big help—Millie has a good measure of Incorruptible Pure Pureness but doesn't do abstracts, Meryl tends to be a realist, and his best friend is an Anti-Hero. And a mercenary assassin and The Mole.
Rem. Everything Vash believes in the main narrative Rem taught him in the backstory.
In a similar vein is Tendou Rushuna from Grenadier, who is a more Martial than Vash, but has likewise never killed anyone, even in the face of them apparently killing a new friend of hers. Even her name is a play on this: Rushuna is a play on a Rushana Buddha, a statue exemplifying the essence of the Buddha, while her surname, Tendou, translates to "Heavenly Path."
Mai Tokiha from Mai-HiME is an interesting case. She spends much of the series struggling to come to terms with her feelings, and is capable of expressing a wide range of negative emotions, ranging from mere disgust to violent rage. In spite of this, she seems to be the type who wants to see the best in people, and never seems to be able to bring herself to feel actual hatred towards anybody, even those who have tried to hurt her. Furthermore, despite her claims that she doesn't have "the time or energy to deal with other people's problems," when push comes to shove she's just not the type of person who can abandon others when she has a chance to help them. In the end, it's her love that allows her to save her possessed best friend/veritable little sister Mikoto, as she chooses to meet Mikoto's berserk rage with open arms and hope that her feelings can reach the other girl.
Nanoha Takamachi from Magical Girl Lyrical Nanoha; she helped Yuuno with his jewel seed problem immediately and without needing persuasion. She fought with Fate because of the girl's 'sad eyes' and when Vita attacked she said 'I can't help if you don't talk to me'. she meets most of her friends on the battlefield. It's worth mentioning that the Nanoha fanbase uses the term "befriend" as a synonym for "beat the hell out of". She does, however, possess an astounding success rate for turning villains into lifelong allies.
Belldandy of Ah! My Goddess generally falls into this trope; even her (astoundingly rare) bouts of anger are more likely to result in her forcibly healing the soul of whoever she's fighting, rather than harming them. When she's drunk (on cola), she goes around causing small miracles to help animals, children, the elderly, stray animals, demons, inanimate objects, and anything else she lays eyes on.
Ginji Amano from Get Backers is even referred to by this moniker several times in the anime and manga, and is very much loved and respected by his allies as a result of his Love Freak tendencies. When his Super-Powered Evil Side kicks in (partly because he's the kind to want to take on others' pain and suffering), you'd never believe it...
Misaki of Kidou Tenshi Angelic Layer; not only her core circle of friends but everyone she's ever fought comes to every one of her matches, cheers for her to win (even the ones that hated her at first) and tries desperately to find out what her opponent's secret is, even though she can't accept any help during the match.
Judai Yuki/Jaden Yuki of the Post ModernYu-Gi-Oh! GX. Originally used straight and frequently noticed and discussed by characters like Sameshima, Saiou, Asuka, Ryo, and Edo; but by Season 3 the pressure of being everyone's source of strength and inspiration is finally too much for him. His True Companions' dependence on him was the key the next Big Bad used to kill them, and Judai's heartbreak at his failure to live up to being this character contributed to his fall to The Dark Side. It took him a lot to pull himself back from the despair.
Kambei from Samurai 7 is a downplayed example. He inspires great loyalty with words alone, and he forgives and sees worthiness where no one else would. He protects Kanna Village for nothing but rice. However, he's also jaded because of the war and so he finds Katsushiro's idealism irritating.
This is epitomized by his decision in the ending: rather than returning to private practice, Tenma signs up with the MSF, proving that he's willing to take bullets to help complete strangers. All this after a sociopathic Manipulative Bastard devotes himself to putting him through hell and showing him that this is a Crapsack World.
Alphonse Elric from Fullmetal Alchemist generally is considered the level-headed brother who always looks on the bright side of life. He has also converted two chimera soldiers to his cause just by showing them that they are still human.
Gon Freeccs from Hunter × Hunter but downplayed. He is extremely nice and forgiving, and has a tendency to make people like and admire him. But he is more self serving than your typical shonen hero and he is also The Fool to an extent, mostly because of sheer brute strength and dumb luck.
Kazuki Muto from Busou Renkin. Declares the intention to protect everyone, and will defend people who've been trying to kill him if he thinks they're redeemable. One of them immediately turns around and offers her own life to save Kazuki from her brother — so it works. He's nice to everybody, he tries to save everybody, and even helps people who were killing him not five minutes before, even people who were killing him five minutes previously, then stop, then betray the truce, he'll still help them!
Sora Naegino from Kaleido Star, despite being bullied by some of her companions and having to face Training from Hell to compensate for her lack of training compared to others, actually manages to win the hearts and respect to even her most bitter rivals.
Sophie also has some elements of this, being a kind yet determined girl who alongside her brother Leon works hard to fulfill her dreams. Too bad she's also the Sacrificial Lamb.
The Digimon, more often than not has one of these. Masaru picks up where his father Suguru left off as far as reaching out to Digimon and trying to create the world where Digimon and humans can live together. Daisuke, Takato, and Takuya also have their moments.
Taichi's younger sister Hikari plays the role straight in Adventure, but plays it for drama. it in 02. Her Crest of Light helps her channel spirits, reach for others and all. However, in 02 Hikari shows huge emotional damage as she's much less able to handle the stress, to the point of having two serious Heroic BSODs that Takeru and Miyako have to pull her out from.
D.Gray-Man's protagonist, Allen Walker. He's intensely dedicated to destroying Akuma, and by gum, he'll save everyone doing it. His Empathic Weapon is powered by his will to fight for both the well-being of the living and for the salvation of the Akuma's souls, who systematically try to kill him and all of his friends. Without the will to save both of them, the weapon won't work. In fact, it showed him getting an epiphany and coming to the realization that he loves both humans and Akumas alike.
Nana "Hachi" Komatsu from Nana can turn even the toughest punk rocker into silly putty just by smiling cheerfully.
Chrono Crusade: Mary Magdalene fits all of the requirements to a T. Gentle and constantly smiling, Mary shows kindness even to the demons who kidnapped her, becoming like family to them. She willingly helps them when a prophetic vision revealed to her that she would be killed by one of them. In the anime, they decided to make it obvious who she is by giving her stigmata, as well.
Tengen Toppa Gurren Lagann: A constant inspiration to others? Check. Never seems to express genuine rage even during combat? Check. Group starts to fall apart when he's gone? Yep. This may sound slightly insane, but that sounds a lot like Kamina, but downplayed since he's also a hot blooded maniac who tends to be mostly battle addicted and perverted to he point of shamelessness. After his death, the role is debatably shared by Nia and Simon also they play this straighter.
Further cementing things is Kamina getting a final Crowning Moment Of Awesome from beyond the grave when he rescues the trapped Dai-Gurren Brigade from the Anti-Spiral's inescapable Lotus-Eater Machine, allowing them to save the day.
The titular character from Galaxy Fraulein Yuna is a prime example of this. An 9-year-old out-of-control android girl, Ayako, is destroying a hospital in a temper tantrum, and all the characters (almost all former enemies) are trying to contain the destruction and destroy the android. Not Yuna; she admonishes "You're going in to fight an enemy, I'm going in to make a friend!" Which she does. Her title is the "Savior of Light".
Jiyu Nanohana from Jubei Chan. She's the reincarnation of one eyed Yagyu Jubei, and she turns into a powerful swordswoman when she put on a magic eye patch she becomes a bad ass, busty version of her predecessor. Jiyu, who is nicknamed Jubei-Chan by her father who ghostwrites samurai novels, doesn't want to hurt anyone and hates turning into Jubei. She is pressured into it when she discovers that the Ryujoji clansmen who keep trying to kill/challenge her as Jubei end up living happier lives after she defeats them, because her Healing Shiv frees them from the magically-enhanced hatred that dominated their (after)lives. Jiyu fits this archetype well; not only does she go to great lengths to avoid hurting the people who are trying to fight her, but everyone loves her — even opponents she has defeated will go to great lengths to protect her.
Relena Peacecraft. Although by Endless Waltz she has abandoned the doctrine of total pacifism as unrealistically idealist, she certainly tried to make it work, and went on to become an ambassador of peace. More importantly, she plays a large role in bringing Heero around from the emotionless "kill whoever it takes to accomplish the mission" mentality brought on by his implied Training from Hell into someone capable of sympathy.
Quatre also counts a lot toward this, being the Apologetic Attacker and kind heart of the 5 Gundam pilots. Unlike others, however, he does have his limits: when his father dies, his favorite sister is injured and he's betrayed by his colony, he goes violently insane under the effects of the ZERO System and doesn't recover until a friend makes a borderlineHeroic Sacrifice. Then he reaffirms his All Loving Hero-ness by making what he can to atone and slowly but surely maturing into The Leader of the Gundam pilots and keeping the group together and snapping the aforementioned friend out of his Easy Amnesia.
Negi Springfield starts looking like one of these (exhausts himself helping his students, befriend a vampire out for his blood) but as the manga progresses, he starts becoming more painfully aware of his own weaknesses, and is willing to use questionable means to combat them. However, his motivation is as pure as ever and so is his Honor Before Reason.
His father Nagi is a straighter example; he more-or-less saved the world singlehandedly, ending a world war in the process, and he's one of the most popular people in the magic world. So of course, he had to go MIA right around the time Negi was born.
The manga has another example: Princess Arika, Negi's Missing Mom. She was accused of being the opposite, as well as tried and apparently executed, but the common people didn't buy it because she was genuinely kind to them.
Albert from Gankutsuou becomes something of this at the end. The Count destroys his family and his life, murders his best friend who loved him, and tries to kill him in front of his father. However, instead of wanting revenge, he readily forgives The Count and uses The Power of Love and Forgiveness (along with a kiss) to save the day.
Shibuya Yuuri. He doesn't even kill the Big Bad. He befriends dragons, breaks down race walls, has managed to overturn every foreign policy his country ever had in less than a year in favor of world peace, and trusts and loves everyoneeven after he's been betrayed by them twice, then used as a Person of Mass Destruction to wipe out an entire naval fleet. It gives his bodyguards migranes and is driving his fiancetoward an aneurysm.
Susannah Julia Von Wincott, Yuuri's previous incarnation is the absolute embodiment of this trope. Yuuri is said to have inherited many of her former traits.
In fact, apparently God engineered him through several reincarnations for this. Soushuu states that Yuuri himself was required to put the final seal of worthless mediocrity on his perfect vessel, but Shinou wanted him to outright surpass him so as to defeat Shoushuu.
Akira from Aoi Hana has some of this, since she has the ability to be friends with most other girls. Later she is surpassed in that regard by Haruka, who drags everybody along by sheer enthusiasm.
Marin from Umi Monogatari is prone to randomly hugging people and saying that she loves them. Kanon, her sister, a giant turtle. It doesn't matter. The girl's got plenty of love to spread around.
Both Garrod Ran and Tifa Addil in Gundam X. Garrod, because he managed to subvert almost any of poor Tiffa's horrendous visions and help humanity Screw Destiny; Tiffa, because her kindness let her reach for Garrod and show people what was needed to get the peace they all needed. No wonder they fall in love and get together in the end.
Yuuto Amakawa from Omamori Himari is an example. While demon hunters and ayakashi are generally depicted as being very violent towards each other, Yuuto refuses to have anything to do with demon slaying, and strongly believes that demon hunters and ayakashi can live with each other in peace-and was willing to step into a fight armed with only his belief in Shizuku's ability to let go of her past and return to a peaceful life.
Lelouch's half-sister, Princess Euphemia vi Britannia: always chipper; loves everyone; doesn't get angry even when people threaten her with death, which happens more often than you might think. To the annoyance of her family, she takes bolder and bolder steps to fight anti-Eleven (that is, anti-Japanese) prejudice, and eventually she sacrifices her place in the royal line of succession to give herself the leverage to make an attempt at lasting peace between Britannia and Japan / Area Eleven. She also places herself in danger for the sake of others on no less than three key occasions. Then she's accidentally geassed into a mass murderer.
Shirley Fennette. Unlike Euphemia, Shirley generally avoids discussions of politics and current events, but like her, she actively and bravely opposes prejudice and cruelty whenever and wherever she sees it; she feels tenderness toward everyone; she can't bear to see anyone get hurt; and she's nearly always chipper — except when jealous (back to that in a moment) or when things are going really, seriously wrong. Admittedly, she gets upset whenever she suspects her beloved "Lulu" of liking another girl more than her — which is often — but even then, she's never mean, just, at worst, sullen and gloomy. Shirley is a bit how Euphie might have turned out had Euphie not been stuck as a princess of the world's greatest superpower. She's killed because she was a threat to Rolo's plan to have Lelouch all to himself.
Princess Nunnally, Lelouch's younger sister and reason for living — and, though she has no idea, for killing. Like her older half-sister Princess Euphemia, she's always chipper, always ready to think the best of everyone. Unlike Lelouch, she has no interest in revenge against her family (or anyone else) for the many ways they have wronged her; she just hopes the world will become a nicer place, where Britannians and Japanese can live side by side in peace, and she can return to the family that has betrayed her. Ultimately, she comes to rule over Britannia and remake it into a good nation.
Astro Boy from Astro Boy. Firmly believes that humans and A.I robots can coexist peacefully as equals. Whenever possible, he tries to talk his enemies down instead of blasting them to ashes. Ultimately forgives the Big Bad for all his evil and this causes his final defeat.
Kenji, after his return, becomes this in 20th Century Boys. He saves the world by travelling around singing a song (which in turn makes legions of people idolise and follow him), kills no one and apologizes to the Big Bad for a past misdeed. His attitude is Be All My Sins Remembered and somewhere between bemused and irritated that people are looking to him to save the day.
Toboe from Wolfs Rain. He's about the closest thing a predatory animal can get to a Friend to All Living Things, and, as a clincher, he's willing to protect and die for the guy who's actively trying to exterminate wolves!
Nao from Liar Game, who is incredibly selfless and honest and willing to use the money that she has won to pay off the debts of people who had previously schemed, lied and tricked her. Her reason for continuing in the game is to essentially save everyone in the game.
Nausicaa, from the Nausicaä of the Valley of the Wind manga/anime quoted above, fits this trope to a T. An example: In a scene near the beginning of the manga she meets a cute squirrel-creature. It bites her hand, but she just smiles at it as it gets the biting out of its system, then feeds it. The next thing you know it's her cute animal companion.
Yusei from Yu-Gi-Oh! 5Ds is this even more so than his predecessors, despite his quiet and more mature nature. Hs father named him after a particle that bonded other particles together, because he wanted Yusei to be able to bond people together; he did.
Mayoi Neko Overrun's Otome Tsuzuki. She brings in stray orphans, travels around the world, and is generally a force of derring-do and near impossible feats.
Ouran High School Host Club's Suou Tamaki is an exceptionally compassionate, friendly, and forgiving person with an often annoyingly optimistic outlook on life. All the Host Club members have him to thank for some of the positive changes in their lives. He's extremely genuine and can find the beauty in even the most ordinary thing or person—his compliments toward the girls he hosts or runs into are all honest. Despite his grandmother's verbal abuse toward him he remains motivated to earn her acceptance of him.
Ayase of Okane Ga Nai. He forgives everyone, he cares for everything and everyone, and he will do anything he can to make someone happy.
Kira Yamato refuses to kill others or let others kill. Because of his Bigger Stick he singlehandedly bring battles that would otherwise have casualties, to a grinding halt.
His girlfriend, Lacus Clyne, combines this trope with Guile Hero for interesting results; a shinning beacon of love and forgiveness, who can also her father's political clout and her own social clout to influence events.
World DestructionKyrie fits this to a T. Kind, gentle, and not wanting to fight anyone, he's always trying to find a way to talk things out instead of going on killing sprees like Morte wants to do. He thinks of everyone around him before thinking about himself (which Toppi lampshades this in the manga that Kyrie would give him the water bottle despite the fact he was thirty AND wandering the desert for three days straight.) In the manga when he leaves the group, everyone splits up with Toppi and Naja going with him and leaving Morte and Agan behind after Morte crossed the Moral Event Horizon by blowing an entire village up with innocent people.
Haruka, the main character of the manga Agape. It's explicitly said that her "talent" is unconditional love for everyone, even criminals, demonstrated when she immediately forgives and even comforts a man who had just killed her father. For this reason she is sought out by a special negotiations team.
Noelle from Tenshi Ni Narumon is pure beyond pureness, loves everyone (especially Yuusuke) and in the end saves everyone, especially the two most troubled individuals who caused her a lot of problems.
Other media prove just how true an example of this trope Madoka is if she becomes Kreimhild Gretchen, her witch form, then she will try bring everyone into her care in an effort to bring a world free of pain and despair.
Misaki of Junjou Romantica spends his entire life caring and looking out for other people and will do whatever he can to help someone in trouble. This backfires more than once for him. The one character in the entire series who actively dislikes (and bullies) him, he thinks is his own fault. By the time he's finished his university course he discovers that he's spent so much time looking after everyone else that he has absolutely no idea what he wants to do with his life. ... Until someone suggests that he gets a job where he spends day after day looking after highly volatile authors and managing their fragile psychological health while trying to extract from them some sort of publishable artifact that could somehow be construed as a piece of prose - i.e. become an Editor.
Kamijou Touma from A Certain Magical Index, a guy who just wants to protect everybody. Also, Orsola Aquinas, who forgives everybody.
One of Kotetsu's defining characteristics in Tiger & Bunny is that he cares about the safety and wellbeing of everyone — to the point that he'll be shaken even by the death of some nameless Asshole Victim.
Mighty from Bomberman Jetters is perhaps the nicest person to ever grace any form of media ever. According to his grandmother, she could never figure out his likes and dislikes because of how selfless he was. Despite being regarded as a remarkably powerful and calculating being, he has almost never shown anger to anyone, responds to a death threat from his enemy with a serious polite greeting, and despite his power, tries his hardest to never resort to violence except as a last resort. To top it all off, after seeing his younger brother playing one day, he was convinced that he wasn't kind enough.
Tomoki from Heaven's Lost Property is either a parody of this or a more humane one. While a pervert and having many, many flaws both in character and belief; he is the most loving, caring, compassionate being in the entire Verse and ready to put his life on the line for his friends and those in need without a second thought, to the point that nine out of ten CMOA and CMOH are done by him in the series.
The eponymous Knights Mondo Ohya and Rokuna Hiiragi. Their Badass Creed states "We will protect the monsters from all evil! And keep the peace in Monworld!" Bonus points to the latter, since she is an empath and feels others' emotions.
Shiru would also count, for being able to forgive Zaha and hope for his redemption when there was reason enough to believe that he had already crossed the Moral Event Horizon.
Behoimi from Pani Poni Dash!. Main character Becky even asks her to ask herself if she really believes herself to be a Magical Girl or just wants to help others.
In Trinity Blood, Esther fits better thanks to character development. She starts out as a vampire hating sister who kills someone, but she eventually learns the truth behind the man she blamed for losing her mother figure and decides to join the church and find a way to help vampires and humans co-exist. Eventually she becomes a queen and starts this process, which is where the anime ends. However, the notes from the original novel author before his death paint a bleaker picture.
Miyuki Takara from Lucky Star. Always remains the voice of reason among the four mains. Case in point: When she visits Kagami when she's sick during the first episode, Kagami explains to her some stuff that Konata said moments earlier. The way Miyuki interprets it leads Kagami to wonder if she's a saint.
Romeo from Romeo X Juliet. This becomes obvious when he is assigned to rule over the mine his father created to punish miscreants. Through his gentle nature he manages to befriend all the miners (despite their initial mistrust of him) and later he manages to start a farming village with not only them but also their former guards.
Weed from Ginga Densetsu Weed is a kind puppy who is willing to forgive his enemies even if his comrades don't do so. Thus, this causes some dogs like Kyoushiro to call him out for this.
Taiki from Digimon Xros Wars, he never holds a grudge with anyone and always prioritizes in helping everyone and will jump at the moment when someones life is in danger.
Luffy from One Piece will always be this as long as you haven't pushed one of his Berserk Buttons like hurting your friends (or even worse, hurting his) or the fact that he will fly into a Roaring Rampage of Revenge if you so much as touch his precious straw hat without his permission. Downplayed due to fact, he's a idiot and a criminal, therefore he is by nature selfish and irrational instead of tolerant and rational, he's just not as bad as the evil pirates he interacts with in his series.
Anpanman himself from Anpanman. He shows so much love and kindness that he's even kind to Baikinman, his arch enemy (at least, when Baikinman isn't doing anything bad. They become enemies again when he harms someone).
EnjuAihara from Black Bullet is a 10-year-old cursed child loli who virtually holds no grudge against anyone. In fact, after her status as a cursed child was found out in school, she stated that she'll continue fighting just to protect her former classmates.
When she is forced to marry Hades to protect others only to leave him later, Hades wonders how she could do that since he used the magic lasso on her and she said that she loves him. Wonder Woman says that she never lied; she loves him, just like she loves everybody.
Captain Marvel / Shazam as well. In fact, kind, sensible, utterly selfless and cheerful Billy Batson just might be a bigger example than both of the above.
Spider-Man is ultimately the most lovable human being in Marvel and is the prolific easy going superhero. Throughout the entire Marvel community, he has teamed up and allied with almost every character based on his modesty, compassion, his sense of humor, and his devotion for being responsible. Plus, most stories about him when he's all grown up (considering even the main continuity Spidey, the oldest mainstream depiction, is still only about 24) depict him as "the greatest hero of all".
Captain America. He's the Marvel counterpart of Superman after all. At one point Magneto tried to erase his mind of all prejudice towards mutants. Problem for Magneto: Captain America has no prejudice towards anybody.
Flycatcher, the frog prince of Fables, is universally kind and universally loved for it, and he's the only character who had no sins to absolve or remit under the Fabletown Amnesty. The All Loving Syndrome really kicks in when he receives a purity-powered suit of armor that allows him to resurrect the dead, defeat massive armies without spilling blood, and establish the completely peaceful "Kingdom of Haven" in the middle of enemy territory.
Death of the Endless is quite possibly the friendliest, most compassionate entity in the DC Universe. She loves you, no matter who you are or what you've done.
Zayne Carrick from Star WarsKnights of the Old Republic is a good example of a fool who is an embryonic All Loving Hero. Initially a failing Jedi Padawan whose only power seems to be literal good luck (as in, he spent an hour trying to catch a petty thief for the half-dozenth time, and thus arrived late to what should have been his own murder), over the course of the series he saves first himself; then a junk scavenger and his adopted daughter; then a bunch of captured Jedi; then several million people from an orbital nuclear bombardment; then he tries to save one of the Jedi masters who were trying to kill him. As one of them says:
"You...You... would save me?"
Luke Skywalker in In the Shadows of their Fathers, part of Star Wars Rebellion. He goes to Jabiim to help against the Empire, but the Jabiim people were abandoned by his father as tactically unwise during the Clone Wars, and a number of them immediately want him dead◊. After he's locked up some taunt him and try to beat him up and he's rescued, the idea that his father was a monster seems to hurt◊ worse◊ than the beating... and when the Jabiim are attacked, he fights to defend them without hesitation despite their hostility. Later he tries to stay with them when it would be extremely unwise for the Rebellion, because he is not his father. The Jabiim commander agrees◊(beware the Art Shift), basically telling Luke that he's not as tactical but vastly more humane, and they need him more out there.
Christopher Rudd in Lucifer: He's a damned soul in Hell who manages through skill and luck to become one of Hell's nobility. What you guess he does then? He teaches demons compassion and kindness, gets them and the damned to get along, and finally leads their army to save the Silver City and conquer it in one fell swoop in the name of justice.
Chubby Huggs from Get Fuzzy, he begins every day with hugging his pillow and thanking it for being so soft, and continues in the same way. Needless to say, Bucky is scared to death of Chubby Huggs.
He's also the kind of hero who lets the people he just saved hug him for half an hour until they stop shaking, and Bruce has canonically said that Dick saved him (not the other way around) when he came to live at Wayne Manor.
Karolina Dean is pretty much the glue that keeps the oft-dysfunctional Runaways together, and her willingness to put herself on the line to bring peace has twice extended to offering herself up to potentially hostile aliens in order to end conflicts that her parents started.
Films — Animation
From Hayao Miyazaki, Prince Ashitaka from Princess Mononoke fits the trope as the voice of peace between the humans of Iron Town and the animals/spirits/deities of the forest. Without him the movie would have been much shorter and very bloody.
Lady Eboshi: What exactly are you here for? Ashitaka: To see with eyes unclouded by hate.
Po from Kung Fu Panda is another great example. He is an idiot, a fool and a chosen one, but what really makes him an All Loving Hero is that he doesn't hate anybody, not even Lord Shenwho killed his parents and repeatedly tried to kill him. He still forgave him and even tried to help him let go of his own troubled past.
Moses from The Prince of Egypt. Even after learning that his adopted family were responsible for killing and enslaving his people, he still didn't hate them. He wanted to believe that Ramses could change. He begs him to stop enslaving the Hebrews or the Egyptians and his son will be killed by the Plague. Which happened, and he still takes the time to cry for them even after being told the Hebrews were free to go. Also even when Ramses betrayed him by going to kill all of his people, and had no choice but to close the Red Sea on him, Moses still worried if Ramses was still alive.
Roshan from Ice Age. Roshan is the Peace Child whose love for the animals brings them together in an unlikely herd and leads Manny on a journey of forgiveness to let go of his anger against Roshan's tribe.
Films — Live-Action
Victor Laszlo in Casablanca. It says something about him that the only person in the entire movie who isn't in complete awe and admiration of the utterly heroic and saintly resistance leader is the Nazi officer who has been sent to capture him, which is a ringing endorsement if ever there was one. He's so noble that he doesn't hold a grudge that his beloved wife, believing that he was dead, has fallen in love with another man, and his example is so powerful that that other man is eventually quite willing to sacrifice his one chance at happiness by convincing her to stay with him.
Sergeant Elias K. Grodin from Platoon which makes his dramatic death scene all the more powerful.
Terrence Malick's The Thin Red Line has this in the character of Pvt. Witt, a kind-hearted, wise, philosophizing soldier. (It should be said that he was less saintly in the novel.)
Luke Skywalker in Star Wars. Expanded Universe may differ, but consider that upon discovering his father is a Sith Lord and one of the galaxy's most ruthless killers, he decides—against the advice of everyone—that Dad can be saved from the Dark Side. He turns out to be right.
For the Star Wars Expanded Universe, Luke was this in the early years but starting with the Legacy era he does such things as advocating torture. The mantle was passed on to his son Ben, who wants to redeem people who his father would rather kill. Ben's Sith girlfriend to Luke how he's Not So Different from them.
Shuya in Battle Royale. It's a strange place to find a character of this type, but he does love his classmates.
Pendragon series has Bobby Pendragon. He can make friends with all of travelers in every world in a matter of minutes of meeting them and, it was said on more then one occasion he would be the only one to beat Saint Dane. He does.
Rama, in Ramayana. When a plot causes his rightful throne to go to his brother Bharata, Rama is delighted for his brother's good fortune, without any concern for his own loss of status. When he's exiled by this same plot, he has to talk the entire country (including Bharata) out of coming with him. He collects allies everywhere he goes, just by dint of his goodness. Rama and Sita are supposed to be the great lovers beyond time and space, but the effect is more that Rama loves everyone, everyone loves Rama, and Sita is a member of "everyone".
Alyosha, the third and youngest of The Brothers Karamazov, loves all and is loved by all. Dostoevsky uses an entire chapter to illustrate how it would be impossible not to trust him. Everyone—everyone—in the book confides in Alyosha, and at times these discussions seem to resemble a priest taking confession.
Again from Dostoevsky: Prince Lev Nikolaievich Myshkin from The Idiot is a much darker interpretation of this character type. Myshkin himself is, of course, kind and full of love for humanity—which leads most everyone he meets to assume he's a fool and try to take advantage of him. Then Myshkin himself ends up hurting Aglaya when a climactic Moral Dilemma forces him to choose between his love for Agalya and his pity for the fallen Nastasya.
Sahar Khalifeh's Wild Thorns. Adil, a Palestinian who works in Israel (the book was written in the 70s') to support his nine family members, and always looking out for his fellow workers. He's more than once described as trying "to solve the Middle East conflict all by himself." Even his cousin, who considers him a traitor for working in Israel, cares strongly about him.
Eriond in Belgariad and The Malloreon. He's a small child in the former, although he is very trusting and generous. (He's been raised to be a complete innocent, so that he can handle The Orb, which tends to destroy anyone who touches it with less than completely pure motives.) By The Malloreon he's grown into the position. He's very mild in temperament, and even when he gets very angry (at one point they're in a Temple of Torak and a major sacrifice ritual (human, of course) is going on all he does is put out the temple fires — since if the hearts can't be burned, there's no way to continue the sacrifices.)
Finny in A Separate Peace, who never sees anyone as an enemy, and believes that "when you really love something, then it has to love you back, in whatever way it has to love."
Jean Valjean strives to be this because a The Atoner mindset. He adopts the daughter of a stranger, lifts a heavy beam off another stranger, and spares the man who hunted for a decade for breaking parole, all out of the goodness of his heart.
In turn he learned forgiveness from the Bishop of Digne after 19 years of prison made Valjean bitter and hateful.
Cassie from Animorphs, who spends the most time grappling with the ethics of lethal force out of the entire team.
Ender’s Game: Ender Wiggin loves everyone, including the Buggers he's trying to kill. His friends semi-worship him.
Luke Skywalker, in Luke Skywalker and the Shadows of Mindor. Nick Rostu, who was previously mind-controlled and begged Luke to kill him - but was instead saved - has the chance to blow away thirty-some innocent mind-controlled men and women to rescue Luke and return the favor, and he hesitates
because he had an overpowering intuition: if Luke Skywalker thought he might save thirty innocent lives by sacrificing his own, he wouldn't hesitate. Ten innocent lives.
"Or, hell, one not-so-innocent life," Nick muttered. "Like mine." He flipped the carbine's power setting to stun. "I hate Jedi."
Throughout that book, even when Luke is struggling with despair and mental trauma, he's consistently kind and compassionate to anyone not currently attempting to kill him. When someone is expressing their claustrophobia, he's completely sympathetic to them despite believing he's been through far worse himself. At the end, when to save the day he needs to destroy a mind-control device knowing that doing so will kill the fifty thousand enemies being mind controlled, he does so, but in the Force he stays with all of them to feel them die, so that they won't die alone. And because it's all he can do for them.
Another Star Wars example is Obi-Wan Kenobi in the Clone Wars Gambit novels. Obi-Wan is quite the shining example of the Jedi philosophy of unconditional, unpossessive love, although he is a bit of a downplayed example. His messianic tendencies are usually hidden by his sarcasm and tendency to be less vocal about saving people than Anakin, but his actions speak louder than his words. He nearly kills himself healing the people of Torbel, despite having no training as a healer, simply because it is the right thing to do.
Sorahb in the Farsala Trilogy is supposed to be this, but the trope is subverted in that he never actually shows up- the person everyone believes is him is actually an ordinary man named Fasal.
Tavi definitely wants to be this in Codex Alera, though he does his smiting less with brute force and more with strategy and adaptation. If he were the son of a deity it undoubtedly would be a god of chaos. Actually, he's just the son of the First Lord, which winds up giving him near-godlike furycraft. From a near-godlike fury.
Uncle Tom from Uncle Tom's Cabin, sacrifices his own chance of freedom several times, and eventually himself, when assisting two female slaves in escaping. When he dies, he prays for his torturers, and eventually converts them to a better life. The author intended him to be an example of an ideal Christian.
Live Action TV
Daniel Jackson in Stargate and Stargate SG-1 is The Face of The Team. Whenever they met a new culture, he'd love to sit down and talk with them. Though he hates the Go'ald, his main beef with them is that they abducted his wife (and do likewise to others).
Flash Gordon from the Sci-Fi channel TV adaptation. His idealism and altruism inadvertently brings together several tribes of highly eccentric crazies (including multiple members of the Big Bad's faction), who've spent decades hating each other.
Constable Benton Fraser from Due South makes himself something of a local hero in the slum neighborhood of Chicago he lives in, unwittingly and unerringly winning the hearts of nearly everyone around him due to his constant, unwavering kindness to his fellow man. His partner, Ray Vecchio (and later Ray Kowalski), his friends, and even his boss are fiercely protective of him when danger arises. His lack of street smarts and general naievete can cause problems, though, and they sometimes wonder about his sanity.
Fraser: You mean you're using some promotional ploy to get something for nothing?
Ray: Welcome to the United States of America, Fraser.
Despite being an atoning petty criminal,Jerkass, and a Book Dumb hick, the titular character of My Name Is Earl has a real knack for getting along with people, is actively working hard to become a better person by righting all his past wrongs, in the process making his town a better place, and is willing to make great sacrifices for the people he cares about. Sometimes he relapses, but he brings up some interesting questions on morality and what makes a good person.
Mister Rogers' Neighborhood Fred Rogers is famous for being one of the nicest people ever, both on his show and off. There's an urban legend about him that involves two punks stealing his car. When they realized it was his car, they returned it and included a note that read "we didn't know it was yours".
A story widely told is that a fundamentalist priest/pastor/whatever called on Mr. Rogers to castigate a nearby group of homosexuals. Without missing a beat, Rogers turned to said people and said "God loves you just the way you are."
Sesame Street: Abby Cadabby. Her faith in Oscar the Grouch's heart is unshakable.
Hakuya Ryouga / AbaRed of Bakuryuu Sentai Abaranger. He was immune to the mind-screwing abilities of a Monster of the Week specifically because, in his niece's words, "he doesn't hate anyone or anything." Naturally, evil Ranger Nakadai Mikoto does everything in his power to crush the idealism out of him, but Ryouga never stops believing that Mikoto can be redeemed - and he's proven right.
Gentaro Kisaragi, Kamen Rider Fourze, who in his introduction stated his goal to befriend each and every single person in his new high school. This includes forgiving someone for throwing away a girl's love letter, and being nice to the Jerk Jock "king" and Alpha Bitch "queen" of the school despite their harassment (both verbal and physical). He'll even do it with the Monster of the Week. You have to be really bad for him to refuse you a Last-Second Chance. He even extended his hand to several people who would probably be the last people to receive his handshake, such as the man who killed him, The Dragon who put two of his friends to the Dark Nebula and threatened death to the rest of his friends, and finally the Big Bad. This is the same Big Bad that killed his best friend Kengo Utahoshi. Pyxis, the guy who is the reason Fourze has a Nightmare Fuel page is the only person he's not extended a hand of friendship to.
Parks and Recreation Leslie Knope is such a generous, thoughtful, hardworking person, and so beloved by her friends and co-workers, that she might as well be characterized as the All Loving Hero from Pawnee.
Some of the nicer Doctors in Doctor Who have drifted into this, although Beware the Nice Ones applies. The Fourth Doctor during his Douglas Adams-edited period deserves special mention here, being one of the few Doctors who was outright merciful to his enemies (rather than affable but judgemental), always seeming to hope his opponents would just get over wanting to take over the universe, and (thanks to his anti-authoritarian personality) he fails to see punishment as a good thing even when deserved. The Eleventh Doctor deserves a mention here as well - while he is not very merciful, he strongly prefers intimidating his enemies with sheer force of personality rather than even being so aggressive as to outwit them, readily forgives enemies, and is noted to have a special affinity for children in distress.
The Eighth Doctor, (from what little we see of him) is a bouncy, chatty, charming romantic. Notably, he died trying to get a female pilot off her crashing ship. When she refused to leave with him he willingly stayed onboard until it crashed trying to convince her to let him help her.
Simmons from Agents of S.H.I.E.L.D. is a downplayed example. She's on board with the antagonists getting captured and jailed, but would rather not see them killed, and is the only member of the team to consistently show sympathy with the mind-controlled soldiers they encounter in the main arc. She also seems to genuinely like everybody who isn't an outright antagonist; is always shown to be friendly and interested when meeting new people; is the first one to forgive Skye for betraying the team; and is the only main character never to have succumbed to a Green-Eyed Monster moment, despite the heavy amount of Ship Tease between the show's main and recurring characters, which by rights ought to leave everyone a little miffed on occasion.
Combine an all loving personality with separation anxiety, bipolar disorder, delusion, split personalities and the strength to bend a man in two and you'd end up with something like Daffney Unger, where love leads to violence when it isn't "returned". Dr.Stevie "treatment" did nothing to improve this.
Religion and Mythology
Baldr from Norse Mythology. A Bishōnen, all-loving fertility god, he was such a nice guy that even physical weapons refused to harm. A favourite pastime of the other gods was to throw weapons at him and watch them bounce off because even the weapons liked him too much to harm him. Then along came Loki, the god of mischief, who finds one thing that can harm Baldr: a sprig of mistletoe. One prick from it and Baldr's dead. Then everyone in creation wept for him, even the nasty mistletoe that had done the deed: everyone of course, except Loki who was doomed to be chained to a rock and tortured by a snake until the end of time for his trouble.
Guan Yin from Buddhist and chinese folklore. She's so utterly compassionate that it actually makes her badass.
This is the defining trope for Jesus. The whole "love your enemies" thing is the most obvious. The times when we see him angry are the ones where he's railing against assholes—i.e. people who fail to love anyone (other then themselves) and lead the people astray with their lies.
Nurgle of Warhammer and Warhammer 40,000 holds a deep, paternal love for all living things. This includes bacteria and parasites. Nurgle loves every living thing equally and can't just kill those couple thousand bacteria that live within a sick person. That would be Something-cide!
Similarly, both Devils and Deceivers in the third edition of Nobilis explore why loving absolutely everything is not necessarily a virtuous trait. The Devils love the laughter of children and the beauty of a sunset... but they also love cancer and genocide. In fact, they love cancer and genocide more, because who else is going to love them? As for the Deceivers... to make a long explanation short, let's just say that love doesn't have to be sane or healthy.
Link from The Legend of Zelda will help those around him, no matter what. Affiliation, race and different dimension mean little to him. To him helping is helping. This is quite possible why he’s the chosen of the Triforce Of Courage. It takes true courage to be willing to help so many people without a second thought for your safety.
Super Mario Bros.: Mario and to a lesser extent, Luigi. They are unarguably seen as the paragons of heroism and goodness across the Mushroom Kingdom. Whenever Bowser causes trouble, they will always stop him. The Paper Mario games emphasize Mario's status as a Magnetic Hero. It's also an explanation to why he invites Bowser and other villains to parties, go-karting and other sport-related activities despite all the trouble they've caused him.
Terra Branford from Final Fantasy VI is a clear example of this late in the game. In the World of Ruin, she ends up caring for orphans whose parents were murdered by Kefka and eventually Terra finds her purpose. To fight to protect those who need it as well as ensure a better future. Love drives her.
Celes Chere also fits this trope in the World of Ruin portion of the game.
Zidane Tribal from Final Fantasy IX is an example, despite the fact that he is a lecherous thief. His line in the game's character montage is "You don't need a reason to help people". In fact, multiple characters throughout the game complain about how kind Zidane is to everybody that he meets. This carries over into Dissidia: Final Fantasy.
Final Fantasy X has Yuna. Every summoner has to have this to some degree to go on their pilgrimage in the first place, but Yuna takes it to a whole new level; never speaking harshly to anyone, while still exhibiting a quiet, subtle strength that keeps her going even after the church of Yevon brands her and her party traitors, once the truth comes out about the nature of the Maesters. Her speech to Yunalesca breaks it down perfectly.
Serah Farron develops into this over the course of Final Fantasy XIII-2. At the start of the game, her main drive is to find Lightning and prove that she's alive. By mid-Episode 3, Serah has decided that saving the world should be their goal first and foremost and it becomes her main motivation (but finding Lightning is still very important to her). By the end of Episode 5, she's prepared to save the world despite the knowledge that doing so might doom her to die.
Lloyd eventually transforms everyone in the party (and the world) for the better. He gives corny speeches explaining that everyone has the right to live freely, and inspires comments from his circle of friends on how softhearted, kind, strong, etc. he is. Ironically, the only Dwarven vow he can't stand is number 7, "Justice and Love will always win."
Mithos, the legendary hero from the game's back story, was also this trope. With his three companions and a belief in The Power of Friendship, he saved the world from a magitek war. What subsequently happened to him is revealed later on in the game, and it's not pretty.
Shing Meteoryte from Tales of Hearts is a perfect example of this. He even goes as far as offering Creed, the Big Bad, a second chance.
Kyle Hyde of Hotel Dusk: Room 215 is something of an All Loving Hero who never planned to be. He only goes to the titular hotel on business with his company, Red Crown, and possibly to get a lead on the man he's been pursuing for three years, Brian Bradley. It turns out that all the other patrons of the hotel all have big problems tied to the hotel, Bradley, and the art theft organization he joined, Nile, including manager Dunning Smith, pining for his kidnapped daughter; Jeff Damon, who ran away from home with money and a gun after getting sick of his father's shady legal dealings; Kevin Woodward, trying to get his head around his malpractice suit and his wife somehow (through Nile) producing the money for a settlement; Helen Parker, searching for her lost son who loved to frequent the hotel; Martin Summer, who plagiarized that son's text for a novel and led to his disappearance and others. Through the course of one night at Hotel Dusk, Kyle Hyde manages to "take out [all of their] garbage" with evidence, questioning, and occasional tough love, and give them the strength to keep working to resolve their problems. He doesn't even want to arrest the person he's looking for despite what he did, he just wants to ask him "why?".
The Main Character qualifies if played properly. In addition to helping almost all of the individuals he meets to overcome their crippling emotional and psychological issues, he employs The Power of Friendship with the following means:
The Main Character from Persona 3 also counts. His/Her ultimate Persona is named Messiah.
Talim from the Soul Series. It's most obvious when you play as her as protagonist, but in any case, she actually doesn't like violence and tries to find peaceful solutions, fights unreservedly for what's right when she has to, and can usually be counted on to help her opponent up, full of concern for their well-being, when the fight is over. It's arguably enough to make you wish the plot were a bit deeper.
Yggdra Union has three. Yggdra, the titular character, becomes a wise and loving monarch over the course of the story; the main antagonist, Gulcasa, is one to his own people to the point of dying trying to save them in a really twisted and tragic way; and then there's Nessiah, Gulcasa's friend and tactician (and fallen angel, let's not forget), who is actually something of a fallen messiah figure—he was the real deal once, but he essentially had the idealism and love for all living things tortured out of him when he was thrown out of Asgard for refusing to fight in its wars. It's questionable how pure they are, however, when it's stated and shown outright that all three of them are willing to kill any innocent standing in their ways to their "justice" or rightfulness just because they're on an enemy's side.
Jaina Proudmoore in the Warcraft series. She's probably the most basically decent person (that doesn't go crazy and try to kill everyone) in the entire series, even helping a race she was raised to hate kill her father for peace and to genuinely honor the bond that Theramore acquired with the orcs. This even carries into World of Warcraft where it seems everyone has taken a level in jerkass/incompetent.
Erana from the Quest for Glory games is a powerful mage whose pure and loving influence has remained throughout the different lands even after she is gone, exuding peace and harmony, planting flowers and generally encouraging selfless good deeds. Also, she sealed away an Eldritch Abomination by sealing herself away with it, forever locked inside an icy tomb in order to ensure that the evil being never returned to the world. And you learn all this without even meeting her.
Open Palm Spirit Monk in Jade Empire, who can get a victory by sacrificing him/herself to the Big Bad for the good of the Empire.
The Lightside PC of Knights of the Old Republic, most obviously in his/her interactions with Juhani on Dantooine and with Bastila on the Star Forge.
The Light-Side Exile in the sequel, despite the revelation about the source of their abilities.
Dragon Age: Origins is notable as an exception, while there are usually 'right' options (getting Zathrian to let go of his hate and release the werewolves from their curse, destroying the Anvil of the Void and allowing Caridin to depart from his doomed existence, going out of your way to ensure that Eamon, Connor, and Isolde all survive), almost every choice is in the grey area and many seemingly 'right' decisions (backing the honest, honorable dwarven lord over the fratricidal tyrant of a Prince, helping a dwarven convert set up a Chantry in Orzammar) have far-reaching and negative consequences ( destroying dwarven civilization, setting the stage for a Chantry crusade against the dwarves).
One of the saddest parts of Dragon Age II is no matter how much of a hero Hawke becomes, he/she still loses his/her family, tears Kirkwall apart twice, and sets the stage for Thedas' first world war.
Seliph is seen as both this and The Chosen One in Fire Emblem Jugdral. Being a Shy Blue HairedHumble Hero, the prospect scares him at the beginning, but he eventually lives up to it. In the backstory, the member of the Twelve Crusaders who fits the most is Blaggi the Arch bishop, who not only has a Holy Weapon able to resurrect the death (the Valkyrie Staff) but shows kindness even to the members of the Lopto Sect.
Fire Emblem Elibe has four straight-up examples, only one of them being a main character.
Princess Lilina from Fuuin no Tsurugi is always kind and compassionate, able to melt the hearts of everyone - even the brutally cynical Garret. She's specially sweet to Oujay and Gonzales, the second being an extreme Gonk who was hated by everyone.
Nino from Rekka no Ken not only managed to defrost her best friend and prospect husband Jaffarby nursing him back to health instead of killing him, but she's also unfailingly sweet and gentle to whoever she supports with, and cries when she has to face her adoptive family. The only person who doesn't get this privilege is Sonia, but well... thisisSonia we're talking about. And Nino did seek her approval until she learnt the truth about her.
There's also the main character, Eliwood. He goes through incredible hardships and not only he manages to retain about 80% of his idealism, but he refuses to hate the Big Bad even after he kills his father Elbert and causes the death of his prospect love interest Ninian and constantly shows sweetness to his troupe.
In the backstory, the Seven Heroes of the Scourging have their own All Loving Hero: Saint Elimine, their Magical Girl Warrior and Church Militant. She even founded both her own nation (Etruria) and her own religion (the Elimine church — which still goes strong after centuries)! To drive the point even further, Fuuin mentions that according to her legend, Elimine never died. Once she believed her mission in life was over, she walked up to the top of a tower in the Etrurian capital of Aquleia and calmly ascended to a higher plane of existence. Said place is now known as the Tower of the Saint, and it houses her spellbook (Aureola) and her healing staff (Holy Maiden).
Fire Emblem: The Sacred Stones gives us the almost unfailingly plucky, kind and sensible Princess Eirika of Renais. Even when her naivete sometimes gets the worst of her (like when Fomortiis in Lyon's body tricks her into giving him the Stone of Renais), Eirika keeps being sweet and gentle and willing to fight for the sake of Magvel. She also shows a spiritual side when talking to the local Badass Bookworm, Saleh, and comforts Princess L'Arachel when she gets depressed over the death of her parents when she was a little girl.
The aforementioned L'Arachel claims to be this and has been raised as a Church Militant, but she's more of a Love Freak. She does show genuine traits when she helps Eirika get over the Heroic BSOD caused by the Lyon/Fomortiiis incident described above, though.
Fire Emblem Tellius has one of its protagonist, Micaiah the maiden of dawn. The storyline spends quite a bit of time exploring the trope's negative sides, as the pressure of leading her country's army no matter her personal opinion weighs heavily on her shoulder. On top of that, her enemies have an entirely different opinion of her, as they face her fanatically devoted soldiers that are ready to hold their ground no matter how hopelessly outnumbered as a result of their faith in their miraculous commander...
And Fire Emblem Awakening gives us Emmeryn, the Exalt of Ylisse and Chrom and Lissa's older sister, who goes to the extreme of calmly walking to a cliff and throwing herself off it in front of both Chrom's troops and the Plegian armies, essentially committing suicide to stop both countries from going to war. And she succeeds, becoming a folk heroine for her bravery and selflessness.
And originally in the Fire Emblem Akaneia games, this is a defining trait of both Marth and his childhood friend/fiancee/future wife Caeda. Marth is a compassionate Prince that is willing to forgive most transgressions of the enemy. Caeda is capable to see through the heart of many enemies and win the heart of many enemies to defecting (either that, or other charms), she's also the main cause of why Talys has Ogma as one of its finest soldiers when Caeda protected him from abuses of his employer. Both Marth and Caeda are also protective to each other and to everyone in the army, and insist that they all fight together as one, and no one gets left behind.
StarCraft Tassadar who has ascended to this by the Protoss. Both figuratively and literally.
CLANNAD series has got a lot of characters who can be classified as such, including:
Nagisa Furukawa fulfills this role, especially in the original game and the movie. She gets it from her mother Sanae, who seems to support emotionally almost everyone who has problems.
Kotomi is another example. She doesn't seem to hate anyone, especially after she gets rid of her fears.
Fate/stay night: Emiya Shirou can only feel happy by seeing or making other people happy.
Yuichi Aizawa and Ayu Tsukimiya from Kanon. The former goes out of his way to help the girls he befriends with their problems, and the latter is the one who gives everyone a chance to live happily (aside from Makoto, who is already dead, but implied to have been reborn as the fox she used to be).
Acheron/Kayn'dar in Inverloch. The story is too short to let this trait really bloom, but the signs are all there. He insists on being polite to everyone and trusting everyone until proven otherwise, even the thief who tried to steal from him, and that is despite being raised as the Proud Warrior Race Guy and experiencing Fantastic Racism all the time. The resolution of the Happy Ending doesn't hurt too.
Brian from Think Before You Think is an example. He goes out of his way to save a girl he just met from suicide, and he is just generally nice to everyone he encounters.
Rachael from Guilded Age takes this as a mantra and mission statement, vowing to "Love everyone equally." She's later forced to admit this is impossible (Scipio pointed out that this would mean she'd love her enemies just as much her True Companions) and that coming up with that "philosophy" was basically a panic move in the face of a Relationship Upgrade with E-Merl.
John Egbert from Homestuck. He not only treats his various friends and allies incredibly well, but also constantly tries to makes friends with his enemies and the Trolls (who initially start out insulting and annoying the Kids rather than helping them). He almost never starts a fight and is intensely trusting of others; indeed the only two characters he's genuinely antagonistic towards are Bec Noir and Lord English, two of the three most evil characters in the comic. At first this is deconstructed by showing how naďve and easily tricked he is (we're shown an alternate timeline where Terezi somehow convinced him it was a good idea to attack a boss five times more powerful than him which predictably led to his death) but it's later reconstructed as these very traits allow him to help, support, and lead his allies and friends.
Gary Harrison. Despite being just a One-Shot Character, he is probably the nicest character in the entire series, able to forgive teasing and even threats, and see the good side to everything.
Aang from Avatar: The Last Airbender . He just wants to befriend everyone and takes his role as peacekeeper very seriously, being one of the few people who are willing to give the Fire Nation a chance to redeem themselves.
Avatar Wan even more so, because he wasn't raised that way - that's just who he is, as an adult.
Pinkie Pie from My Little Pony: Friendship Is Magic wants to be friends with everyone. If they hate her at first, she won't stop trying to get them to like her. All she wants is to make you smile!
Fluttershy acts like this as well, mainly towards animals but she does end up getting Discord to do a Heel-Face Turn because of her kindness.
Twilight Sparkle is more cynical and grouchy than the norm, but fills this role in the places that count, more-so than Fluttershy and Pinkie Pie. She's the wielder of the Element of Magic (aka Friendship), in the two-parter episode, "The Return Of Harmony", she is the only one who didn't get Hate Plagued by Discord, and in "A Canterlot Wedding", is able to see through the fake Cadance because she knew the real Cadance so well.
Wander, the hero of Wander over Yonder is a textbook example. His best friend and steed Sylvia is a little harder-nosed.
Mabel of Gravity Falls qualifies for this more than her twin brother Dipper. She holds no illwill towards Pacifica even though she's a jerk to her, and tries being nice to her in return (especially shown in "The Golf War"). In general, she claims she doesn't need revenge to prove anything, she's nice and friendly to everyone and on her parties, everyone is invited!
