A SuperTrope. This trope occurs when two or more people who have a given defining quality in common (let's call it X) are polarized on opposite ends of the good vs. evil spectrum, and the good X must defend a person or group that does not have that quality against the evil X.

{{Sub Trope}}s:
* AnimalWrongsGroup: Humans (wrongly) defends animals against other humans.
* DistressedDamsel, WifeBasherBasher and DateRapeAverted: Men must defend women against other men.
* EvilTwin: Twin must defend non-relatives against his other twin.
* HumansNeedAliens: Aliens defending human against other aliens.
* HunterOfHisOwnKind: Monsters must defend muggles against other monsters.
* PredatorTurnedProtector: A predator refuses to harm their natural prey, instead choosing to protect them.
* SerialKillerKiller: These killers work to defend the nonviolent against other killers.
* {{Superhero}} and {{Supervillain}}: [[DifferentlyPoweredIndividuals Supers]] must defend {{muggles}} against other supers.
* WhiteMansBurden: Part of the trope is about whites defending non-whites against other whites.
* ZombieAdvocate: Someone (most often a human) defends a monster/alien/etc's rights from ridicules of other humans.

Comes with the implication that people with X trait are more powerful, as well as the implication that people without it are more [[TheEveryman "like us"]] or conversely, CloserToEarth than us.

The smaller and more fantastical of a group X is, the more likely this is to result in divided loyalties. A man who refuses to defend a woman against another man, for instance, is a HeManWomanHater, but a vampire who kills other vampires will certainly have at least a moment's pause about killing vampires to save humans.

Related to TakesOneToKillOne and MySpeciesDothProtestTooMuch for one reason why X would bother to defend non-X. May also lead to EnemyMine.

The protagonists' team agenda may be not about obliteration of the Fog, but its initial voyages are made possible only due to having Iona, functionally a Fog submarine, on their side.

He grabs Griffith, demanding that he use his Behelit to save him... and then Zodd shows up to kill Wyald once and for all, since the time for the Eclipse wasn't right.
** Guts and Zodd team up to defend against an Apostle-form Emperor Ganishka. The two part without fighting each other, since Guts' first priority is to get Casca healed and Zodd doesn't want to kill the only human whe enjoys fighting so much.

A family keepsake, actually an obfuscation charm, has depleted, and now he's a target for all kinds of spirits who may fear or otherwise oppose Demon Slayers. Finally, his ancestor has subdued a feline demon long ago, sparing it in return for servitude of protection, so the girl is here to make good on that promise, and she is a supernatural being herself. She drives off a first assailant even before actual chance to explain all this.
