- Tarzan, Tarzan
Tarzan was adopted by gorillas when he was a baby. As a human, he was always an outsider among them. This lessened as he grew older, but it was still there.
Eventually, Tarzan ends up fighting Sabor, the leopard that killed his parents, as well as the child of his adopted parents.
Tarzan manages to kill her in front of his whole pack, triumphantly lifting her body as everyone cheers him on.
- Chihiro, Spirited Away
Chihiro ends up working in an otherworldly bathhouse, hoping to save her parents that got transformed into pigs.
Many of the spirits look down on Chihiro for being a human. Then a polluted spirit arrives, and most of the workers at the bathhouse keep their distance from it.
Chihiro is assigned to clean the polluted spirit. In the process of doing so, she discovers the polluted spirit’s troubles are due to stuck garbage inside its body, which she and the other workers remove by working together.
The polluted spirit is cleansed, and everyone cheers for Chihiro.
- Grunt, Mass Effect 2
Grunt was a lab grown Krogan, a fact other Krogans looked down on him for.
He is allowed to take the Rite of Passage that all Krogans must take. During the Rite, the party is attacked by a giant Thresher Maw. It is possible to kill it, and since killing a Thresher Maw on foot is supposed to be borderline impossible, doing so earns Grunt the respect of the Krogan.
- Slaine, Aldnoah.Zero
Slaine is from Earth, so he always faced strong discrimination from Martians after arriving on their planet.
As fate would have it, he is adopted as heir of one of the 37 Clans of Orbital Knights. Following the death of his adopted father, Slaine takes his place as count.
In order to silence all voices of disapproval over an earthling becoming a count, Slaine single-handedly attacks one of Earth’s most important military bases, a military target that Martians previously failed to defeat in a recent battle.
Slaine is victorious, and is received with respect upon his return, even from other counts.
