Defusing the Tykebomb

Tykebombs are generally raised with people who tell them they're nothing but a weapon and usually treat them like crap. Then along comes someone who's different. When they look at the Tykebomb, they don't see a weapon, they see a messed-up little kid. Naturally, they try and rescue the poor Tykebomb, talking or fighting their way towards them. The Hug Tropes is likely to be their arsenal and expect The Power of Friendship to be used. The one doing the defusing is also likely to be a Warrior Therapist and/or The Messiah.

Sometimes it works, sometimes it doesn't; what matters for trope purposes is the intent.

Anime & Manga
"Benny:"
 * This pretty much is Monster summarized in three words.
 * The whole comedic point of Beelzebub. Poor Oga has his work (and life) cut out for him to prevent his adopted demon spawn from erasing humans off the face of the earth.
 * Naruto doesn't understand how Haku can stand to work for a man like Zabuza, who frequently makes it clear that Haku's usefulness "as a weapon" in battle is why he's kept around . Naruto sees Haku as a person, and tries to make Haku see that he's a person, too.
 * Iruka does this for Naruto himself, as he was pretty much the first adult to treat Naruto like a person - other adults were either distant or hostile, and the kids more or less followed suit. So many of Naruto's enemies are versions of him who didn't even get that level of support (or only got it from a twisted source).
 * And Pain gives us a lesson in how not to do this. You do not leave the Tykebomb on his own until you are sure it is defused. You do not wait for somebody else to teach him the intricacies of his powers.
 * Pain implies that he did not fully trust Jiraiya when he was watching over him and his friends, making this something of a case of the bomb only seemingly being defused.
 * Well, on the one hand, he wasn't a Tyke Bomb, he was a scared little kid with some powerful buried powers. Jiraiya trained him into a Tyke Bomb in hopes that being a ninja would keep him alive--wasn't particularly worried about who Nagato might hurt, 'cause he was a good kid who loved his friends. And it was all fine, and Akatsuki was spreading peace and order and possibly even sunshine, though it was Rain country so probably not...and then Danzou and Hanzou got together and offed his leader slash Morality Pet slash best friend slash Restraining Bolt in the most traumatic way possible. Nice job there.
 * Sven toward Eve in Black Cat.
 * In the second season of Code Geass,  It works, and he gets a loyal pawn, but eventually this goes horrifically wrong
 * He didn't try to get rid of the murderous tendencies at all. He just tried to  Unfortunately all this did was show that an unstable Tyke Bomb is not someone you want on your side if you actually have people other than yourself that you care about.
 * Mireille from Noir assumes this role toward Kirika, particularly toward the end of the series.
 * Kenshin Himura does this to.
 * Nanoha does this to Fate in the first season of Magical Girl Lyrical Nanoha. Of course, this being Nanoha, she defused the bomb with a bigger explosion.
 * And then Erio and Caro do this to Lutecia in season 3.
 * Fate previously reached out to Erio, who believed he was worth nothing after finding out, and lashed out at her and the people looking after him. Interestingly enough, she used essentially the same argument that Caro eventually used against Lutecia- that people who are sad should not hurt others while seeking happiness.
 * Domon Kasshu does this to Allenby Beardsly in G Gundam.
 * Also,  tries this on   in Gundam Seed Destiny.
 * Kamille Bidan attempts this with both Four Murasame and Rosamia Badam, even playing along with the latter's delusion that he's her elder brother in an attempt to help her.
 * Judau Ashta is more successful: Elpe Puru settles into a fairly stable brother-sister relationship with him, and even Puru Two seems headed in this direction by the end.
 * Banagher Links tries to talk There's also an example in the backstory -.
 * Some characters of Kenichi: The Mightiest Disciple (Kenichi himself, Miu, Niijima) are gradually doing this with Creepy Child Chikage Kushinada as an alternative to letting her fight Kenichi. Some want to help her, others are concerned because Kenichi Wouldn't Hit a Girl, let alone a little girl. As a result of all these attempts (especially Kenichi's), she becomes Tsundereish towards Kenichi.
 * In Kekkaishi, Yoshimori is trying to do this to Hiura.
 * And yet.
 * A strange case of this appears in Pokémon the First Movie. Mewtwo rejects the objectification of his creators on his own twice (even stating in the novelization that they treat him like an object), and is already waging war on humanity when our heroes come along. Ash and his friends, fairly quickly, realize that  This process is essentially completed in the direct-to-video sequel, Pokémon: Mewtwo Returns.
 * Rowan does this to Mitsumi prior to the beginning of Pokémon Diamond and Pearl Adventure.
 * In ROD the TV, tykebomb Junior finds Michelle utterly disarming. Anita puts a few chinks in his armour as well.
 * Maka towards Crona in Soul Eater.
 * Black Star had another attempt
 * In Black Lagoon, Rock tries to do this with Gretel(who might really be Hansel), but is unsuccessful. And then.

 * Dominic helps bring this about for Anemone in Eureka Seven.
 * An absolute textbook example of this trope occurs toward the end of Rune Soldier Louie when priestess Melissa walks directly toward an enraged, lightning-bolt-flinging Child Mage named Lilly, who has been raised by the evil Lord Dardanel to be a vicious enemy of the reigning royal family. Melissa proceeds to talk her into a teary-eyed Heel Face Turn.
 * Neon Genesis Evangelion had several characters make the attempt, hindered by their own state of massive emotional trauma. It's not terribly successful. In Rebuild of Evangelion, however, it looks as if the three lead Tykebombs are gradually beginning to defuse each other, though the latter half of 2.0 sure didn't help.
 * In fact, Shinji and Rei appear to have defused each other while Asuka defused herself with help from others, Shinji and Rei in particular.

 * Done in DNA 2, towards
 * Mai does this unintentionally to Mikoto in Mai-HiME, without even knowing what Mikoto's role in the unfolding events really is. Likewise, Miyu wins Alyssa from the Searrs Foundation by being the only person... well, robot... who ever actually cared about her.

Literature
"“Except that—I keep hearing my mother’s voice, in my head. That’s where I picked up that perfect Betan accent, y’know, that I use for Admiral Naismith, I can hear her now.” “And what does she say?” Galeni’s brows twitched in amusement. “Miles—she says—what have you done with your baby brother?!”"
 * Discworld's Sourcery: Rincewind does this to Coin, and the Librarian keeps it good.
 * Lois McMaster Bujold's Miles Vorkosigan starts this job with his clone-brother Mark in Brothers in Arms. His parents, especially his mother Cordelia, pick up the job in Mirror Dance.
 * Technically more of a Thicker Than Water, as in Betan society cloning is a perfectly valid form of reproduction, and as such Mark is a Long-Lost Relative.


 * And Kareen Koudelka seems to have happily picked up where Cordelia leaves off, although Kareen and Mark do meet in Mirror Dance. By A Civil Campaign, the two have gone into business together.

 * At least, not until the season 4 finale  Even in season 5,
 * 24 surprisingly let this work, rather than forcing Jack to kill a child soldier.
 * Odo attempts this with a newborn Jem'Hadar on Star Trek: Deep Space Nine. His attempts to raise the fast-growing child to be more empathetic and less violent fail because the Founders are just that good at manipulating them on the genetic level.

 * In Blaze Union, we learn that Yggdra Union's Hero Antagonist Gulcasa was technically born one of these--his mother attempted to defuse him by forcibly sealing his abilities and then leaving him to go Find the Cure. His father, resenting him for the loss of his wife, started abusing him, and any good the seal did was undone posthaste. According to Word of God, the young Gulcasa was a bitter and violent Empty Shell until Siskier and Jenon befriended him and helped him learn to be a normal little kid again.
 * Attempted in two routes of Fate/stay night with Ilya.
 * Done to  in FE: Shin Monshou no Nazo.

 * Danny Phantom has Danny telling his Opposite Sex Clone that Vlad is merely using her as a tool instead of the daughter she thinks he is to her. She obviously doesn't believe this and spends most of the episode in deep denial, attacking him and the like to prove otherwise. Of course, since Vlad is the series' Big Bad, Danny is right. Danielle manages to have a change of heart as a result and worked alongside him.
 * Ratchet combines awesome and heartwarming to do this to the moment he wakes up, rejecting the Elite Guard's role for him as master of a mindless Person of Mass Destruction.
