The Kid Pirates' flag represent the usual grinning skull having Kid's hairstyle and wearing the latter's square shaped goggles on its forehead. In the background there is the traditional cross-bone pattern plus what seems to represent two knives forming a cross as well. Moreover, on each sides of the skull there are flame-like patterns.
Secondary Jolly Roger
As with the Whitebeard and Big Mom Pirates, the Kid Pirates also seem to possess a secondary, simpler symbol, as seen worn by Wire. Its appearance is similar to the face of Jack Skellington from "The Nightmare Before Christmas" franchise. But, overall, this Jolly Roger is a smiley with a Glasgow smile. The smiley skull is surrounded by nine, evenly spaced spikes around the circumference.
The most significant aspect of their appearance is that most, if not all of the Kid Pirates have heavy metalesque appearances. Also, many of them seem to wear leather in one way or another. There are 4 named members in the crew: Eustass Kid, Killer, Heat, and Wire. At the auction house, they stated that they might purchase someone who caught their eye. However, it appears that nobody interested them as they never ended up bidding on anyone.

The Kid Pirates had one known island under their control, which served as their base of operations. It is a small mountainous spring island with even bigger trees. At the base of the largest mountain was a castle where Kid, Hawkins, and Apoo formed their alliance. It is unknown what became of the island after the Kid Pirates' defeat.
They are most known for dealing major destruction and civilian casualties along their route through the Grand Line and towards the New World. Furthermore, the entire crew managed to withstand the blast of Haki released by Silvers Rayleigh, a testament to their overall strength. In spite of their great potency in battle and overall level-mindedness, the members of this crew display an innate sense of haughtiness. They, like the other super rookie crews, were able to escape from Kizaru's raid despite being weakened by a Pacifista. After the timeskip, it is apparent that their strength and influence have increased, as evidenced by Kid and Killer's bounties being raised and the fact that they were able to establish a base on an island. They have also formed an alliance with the Hawkins and On Air Pirates. However, after the crew's defeat at the hands of Kaido, the alliance appears to be over as Scratchmen Apoo and Basil Hawkins are currently allied with the Beasts Pirates.
The Kid Pirates' Ship is called 'The Victoria Punk'. Their ship continues the theme of heavy metal, with a bizarre skull as part of the deck, resembling some heavy metal bands' stages. Their ship was coated with the Yarukiman resin, allowing it to submerge underwater by reducing its buoyancy, and withstanding the water pressure of 10,000 feet.
Summit War Saga
Sabaody Archipelago Arc
Eventually they reached the Sabaody Archipelago, where they docked and prepared to enter the New World. Subsequently they visited the Human Auction House, where their captain voiced an interest in purchasing a slave, although in the end, they ended up purchasing no one. After Luffy hit Saint Charlos, and the Straw Hats moved into action, they remained at the auction house and witnessed the ensuing chaos. However when Rayleigh appeared, they were subjected to his Haki just like everyone else in the auction room, though every present Kid Pirate easily withstood Rayleigh's Haki. Afterwards, realizing that the Marines were the greatest threat at that time, Kid and the other two captains fought the Marines. Eventually Killer and Heat joined the fray as well, and they soon cut a path through their enemies and managed to escape the Marines. Shortly afterwards they were confronted by a Pacifista which they mistook for Bartholomew Kuma. While struggling to fight it, they once again allied with the Heart Pirates to fight off the Pacifista. The battle was concluded offscreen, but every member survived the fight without any major injury.
The Kid Pirates having escaped the Marines were able to stay on the Archipelago a bit longer and were able to watch the Battle of Marineford, where they witnessed, at a distance, the death of Whitebeard and how Luffy partook the war. They eventually moved onto the New World, where they brutally crucified Haritsu Kendiyo and his crew.
During the Timeskip
During the timeskip, the Kid Pirates continued to rise in infamy, as evidenced by Kid and Killer's bounties increasing.
At some point after this, the Kid Pirates went to Big Mom's territory and injured one of Big Mom's Sweet Commanders, as well as plundering something. However, they were quickly forced to flee afterwards.
In addition, the crew became powerful enough to establish their own base on an island. They also appear well connected, as they are well aware of dealings within the underworld.
Punk Hazard Arc
The Kid Pirates met with the Hawkins and On Air Pirates in their own hideout, though the alliance nearly broke apart due to Kid and Apoo getting into a fight because of a lingering grudge. However, Killer managed to calm things down and remind the various parties of their alliance. The captains agree to the alliance, and the three crews start plans to take down a Yonko.
After reading the news about Doflamingo's defeat, Kid and Killer dined with Hawkins and Apoo. They learned that Luffy and Law's target is Kaido and were glad as their intended Yonko target is Shanks. Some time later, they were alerted by what seemed to be an earthquake. They quickly investigated the source of the commotion, which was a large crater on the ground in the shape of a human. The alliance then came face-to-face with the Yonko, Kaido.
Wano Country Arc
Kid was imprisoned in the Udon region of Wano Country where he met Luffy again when he was placed in a cell next to his. Killer was forced to eat a failed SMILE and later became known as the assassin "Kamazo". According to a Wano newspaper, he was responsible for a street murder on the eighth street in District 2 of the Flower Capital.
After the chaos at the palace, Kamazo was hired by Kurozumi Orochi to kill the kamuro Toko. He then pursued Toko and Kozuki Hiyori to the Ringo region, where he came across a confrontation between Roronoa Zoro and Gyukimaru. Zoro then clashed with Killer in order to protect Toko and Hiyori. When Zoro was distracted by Gyukimaru, Killer manages to land a grievous hit on him. However, Zoro was able to take one of his scythes as a result and strike him. After that blow, Killer fell to the ground defeated.
Later on, for failing to kill Toko, he was sent to the Prisoner Mine at Udon alongside Kid, who previously escaped and got recaptured. Kid questioned him on what Kaido had done to him and the fate of their crew, but Kamazo could not answer through his laughter and tears. Both were then sentenced by Queen to undergo water torture.
