Played with when Shockwave retains leadership of the Decepticons by kicking Megatron's ass however, Shockwave clearly didn't want to fight, because he's all about logic (which to him is 'whatever will achieve the best outcome') and the Decepticons were at the time under danger from the outnumbered and wounded Autobots.The Go-Backs, at least later on in the series, appear to have the same thing. Though their leadership is usually inherited, tribe members can also challenge the chief and take over. The Wolfriders in ElfQuest are another example.

The wolves won't talk, so he challenges the alpha male for leadership.

In Fables, Mowgli finds a wolf pack who might know where to find the missing Bigby.

There's also an ancient tribal clause that grants the right to challenge Black Panther to one-on-one combat, and if the challenger wins, they become the new Black Panther.

In the Black Panther comic books, there's an annual event where every citizen of Wakanda has the right to challenge T'Challa for both the Black Panther identity and leadership of the country.

Geriatrix also gets in on the action, but nobody pays attention to him. The new deed-owners go to the village, and eventually end up challenging Vitalstatistix to an election.

In Asterix and Caesar's Gift, Caesar grants the deed to the village to an ignoble retired legionary as a prank, who in turn trades it for a jar of wine.

Vitalstatistix manages to win without the magic potion by running around the ring and eventually punching the exhausted adversary - but he refuses to take control of his village, who then go back from Gallo-Roman to regular Gaul.

Asterix and the Big Fight: in order to destroy Asterix's village, the Romans call a Roman-loving Gaul chief to fight Vitalstatistix, using the fact that the druid Getafix is currently neutralized.

though he still covertly serves the World Government as a spy among the Blackbeard Pirates, with his very public falling out providing a perfect cover story. Apparently things were too bitterly divided for anybody to bring up a more reasonable compromise like 'Hey, this Kizaru guy is an Admiral too, does anybody object to him?' The winner would be Akainu, but he spared Aokiji's life in a rare moment of sympathy, and the latter proceeded to ditch the Marines, having no desire to serve under his rival or a form of justice he was opposed too. The feud was so bad, that the higher-ups just went ahead and had the two fight a Duel to the Death on the barren island of Punk Hazard to get the position filled already. Unfortunately, the conflict over the Fleet Admiral position degenerated into a variation of this between Aokiji and Akainu, with no small part due to their opposing ideologies and the fact that they hated each other. While technically this rule can apply to the captain of any division, only the Eleventh actually uses it. This is apparently the normal method of transferring leadership in the Eleventh Division, the winner not only gaining a Captain's rank but also the hereditary title of 'Kenpachi'.

In Bleach, Kenpachi Zaraki gained his position as Captain of Squad 11 by walking in and killing the last captain Shinigami rule states that this works if done in front of 200 witnesses.
