One Piece Trivia about Yonko

The Yonko are the four most notorious and most powerful pirate captains in the world, but are neither allies nor enemies of one another, preferring to remain autonomous under most circumstances. These four individually reside within the second half of the Grand Line (known as the "New World"), exerting impressive influence and control over dozens of other pirate crews and self-governing islands. In the decisive Battle of Marineford, Whitebeard, one of the Yonko, met his end towards the climax of the Whitebeard War. Blackbeard, his killer, subsequently usurped his position. Shanks, another member of the Yonko, arbitrated a ceasefire to end the aforementioned war.
 

• It is said that once Elizabello II has gathered enough strength to the point where his punch can knock down even a Yonko.

• Marshall D. Teach is the only known person to serve as both a Shichibukai and later a Yonko.

• All the Yonko's crews are named after their respective captain's epithet.

• All of the Eleven Supernovas are known to be involved with at least one Yonko:

• Monkey D. Luffy looks up to Shanks as a role model and personal hero, allied himself with the Whitebeard Pirates in the Battle of Marineford, and wishes to dethrone Kaido and Big Mom. He despises Blackbeard for causing the conflict that led to his brother Portgas D. Ace's death and attacking Baltigo, the home of his other brother Sabo.

• Roronoa Zoro, as a member of Luffy's crew, is part of the alliance to defeat Kaido, and most likely receives an amount of anger from the latter and Big Mom, due to Luffy's behavior on Fishman Island and Dressrosa. He also considers Blackbeard an enemy.

• Trafalgar Law made an alliance with the Straw Hat Pirates specifically to take down Kaido, though as a pretext toward his real motive of eliminating Donquixote Doflamingo, hoping to anger Kaido into killing Doflamingo. However, after the events on Dressrosa he now aims to take down Kaido with the rest of the Ninja-Pirate-Mink-Samurai Alliance. He might also be on Big Mom's radar, as when she asked Caesar why he wasn't able to complete his experiments despite her orders, he accuses Luffy and Law to have interfered.

• Eustass Kid invaded Big Mom's territory during the timeskip and later attacked two of her crew's ships. He formed an alliance with Scratchmen Apoo and Basil Hawkins in an attempt to dethrone Shanks. After unknown circumstances involving Kaido after his failed suicide attempt, Kid seemingly fought Kaido, but was badly defeated and imprisoned. Kid was later mentioned by Kaido when the Yonko jokingly told him to pass a message along to Luffy and Law that they should run for their lives after interfering with his plans.

• Killer is part of Kid's crew and took part in his actions against Big Mom, and in the Kid-On Air-Hawkins alliance. After Kid was defeated by Kaido and Apoo having joined Kaido's forces, his current affiliation is unknown.

• Scratchmen Apoo invaded Big Mom's territory during the timeskip, and later joined Kid's alliance in an attempt to dethrone Shanks, and was approached by Kaido after a failed suicide attempt. After unknown circumstances, Scratchmen Apoo became a subordinate of Kaido.

• Basil Hawkins joined Kid's alliance in an attempt to dethrone Shanks, and was approached by Kaido after a failed suicide attempt. After Kid's defeat and Apoo having joined Kaido's forces, his current affiliation is unknown.

• Jewelry Bonney was seen crying after Whitebeard's death, and was later captured by Blackbeard, though managed to escape custody of the Marines after being captured by Akainu.

• Capone Bege is currently a subordinate and son in-law of Big Mom after he invaded her territory. He married her daughter, Charlotte Chiffon.

• X Drake is currently a subordinate of Kaido.

• Urouge invaded Big Mom's territory during the timeskip and defeated one of her Four Sweet Commanders, angering her. He was later shown talking to Kaido about his motives for suicide.

• Out of all the total Yonko, Shanks is the only one to have human-like body size and proportions.

• Three of the Yonko have been shown to be habitual alcohol drinkers: Shanks, Kaido, and the late Edward Newgate.

• Kaido is the only one of the Yonko who has not been seen to have a personal flagship.

• Both Kaido and Linlin shared some similarities with one another

• Both dreamed of creating something through the power of science, through dealing with the scientistCaesar Clown (Kaido dreamed of creating a crew composed entirely of Zoan-type Devil Fruit users, via Caesar's Artificial Devil Fruits; Linlin dreamed of dining with her diverse family at eye-level, via Caesar's falsely promised Gigantification-drugs).
• Both never made a proper appearance til the second half of the series.
