** The most powerful example would have to be Nami and Nojiko's adoptive mother [[MeaningfulName Bell-mere]], who sacrificed herself for her daughters because she refused to deny that they were hers. Nami herself struggled with the concept of Bell-mere being her mother but not sharing her blood, but at the end of the day loved Belle-mere deeply, and her death still [[HarmfulToMinors traumatizes]] Nami to this day.

** Franky loved his mentor Tom as a father, since Tom was the one who found and raised him after his actual parents abandoned him. Learning from Tom and seeing him (along with [[AloofBigBrother Iceberg]]) work so hard at building the Sea Train inspired Franky, who had been building his own battleships by that point. When Spandam of Cipher Pol used Franky's own ships to kill civilians and injure Tom, Franky had a HeroicBSOD and denounced all his ships. Tom forgives him for the injury easily, but slaps Franky when he denounces the battleships as his own, saying a parent cannot deny their child even if the child hurts people. When Tom is then arrested by TheGovernment, Franky goes ''ballistic'', leading to Spandam's skull getting smashed and Franky trying to stop a train with his bare hands just to get Tom back.

** Piccolo is one to Son Gohan (they provide the image on the main page), the offspring of his one-time enemy Son Goku. However, it's not mutually agreed on -- Piccolo takes Gohan under his wing by force after Goku sacrifices himself to kill Raditz so that he can train for the arrival of the Saiyans. Fortunately, Gohan toughens up and Piccolo softens down. Soon, they are truly close enough for Piccolo to be considered a father figure. He even [[HeroicSacrifice sacrificed himself to save Gohan's life]], although he was later resurrected thanks to the Dragon Balls. Gohan would wear a costume similar to Piccolo's when fighting on Namek (until Vegeta gave him Saiyan armor), and chooses to wear a battle costume made by Piccolo--rather than Goku's gi--when facing Cell.

* ''Manga/{{Bleach}}'': Just as [[LikeASonTome Yamamoto sees Kyoraku and Ukitake as his own sons]], they in turn see him as a father.

** Jigoro Kuwajima practically became Zenitsu’s grandfather after taking him under his wing by freeing the troubled youth from the woman pilled with debts and Zenitsu definitely sees him as such, [[spoiler:his death was enough to make Zenitsu turn more serious than he had ever been in the series till then, fighting the cause of his death, the traitor pupil Kaigaku, without ever relying on his trance sleep mode]].

** [[Anime/Dororo2019 2019 anime]]: Dororo is forced to take up the role while traveling with Hyakkimaru, who is smart, skillful, and an absolutely horrifying in battle, but has social and language skills of a toddler. He needs some serious help while interacting with the world outside of battle. Dororo is ten and easily annoyed despite his love for [[FamilyOfChoice Hyakkimaru]].

** [[ChildSoldiers Rickert]] has looked up to Guts ever since he saved him during Gut's first siege on a castle so it's natural he sees Guts as a heroic father figure/BigBrotherMentor. Rickert always defended Guts from Corkus's jibes and was deeply sad when Guts left the Hawks. Rickert was delighted at Guts's [[DynamicEntry timely return]] but is horrified later when he discovers Guts and Casca as the only survivors of the [[DespairEventHorizon Eclipse]] [[spoiler: which Griffith caused]]. After Guts tells him about the Eclipse, Rickert is not swayed by Griffith and his kingdom of [[FalseUtopia Falconia]], [[ArmourPiercingSlap slapping]] him when Griffith offers him to join his new band of hawk showing UndyingLoyalty to Guts.

*** [[spoiler: Sanji's loyalty to Zeff even rivals his loyalty to Luffy, and when his biological [[ArchNemesisDad asshole father]] blackmails Sanji using Zeff's safety, Sanji is briefly forced to (violently) sever ties with the crew despite being the [[LoveHurts last thing]] he wanted. After reuniting with his crew, Sanji declared to Judge's face that ''he wasn't his son,'' at which Judge was uncharacteristically humbled]].

* ''Manga/OnePiece'':
** Happens a lot in the series as most of the characters are [[ParentalAbandonment orphaned or abandoned at a young age]].

*** Genzo is seen as a father-figure to Nojiko and Nami, telling Luffy in no uncertain terms he would hunt him down and kill him if he ever did anything that took Nami's smile away. Genzo also flips out of at Nami provacative wanted posters and dress sense in true overprotective dad style.

*** Actually Naruto and Tsunade’s bond may be even deeper if you take into consideration Mito Uzumaki is Tsunade’s grandmother, which means Naruto and Tsunade are indeed [[EveryoneIsRelated related]]. Specifically if this troper has done the math right, she's his great aunt.

* In ''Manga/TheRedRangerBecomesAnAdventurerInAnotherWorld'', Idola's father died some time after losing the WizardDuel that cost him his position as the Royal Family's Wand. She's since been raised by Poseidon, who loves her as though she were his own granddaughter.

The family agreed, but they're one step away of taking the girls away if the young and stubborn Yuuta fails to raise them properly...

** Iruka Umino unconsciously avoided Naruto for a while because he was the living vessel for the Kyuubi, which killed his parents.
