Page One

Page One is a Headliner and one of the Tobiroppo of the Beasts Pirates. Page One is a young-looking man with long purple hair that is all swept off to one side while the other appears to be shaved off. He also has sharp, angular eyes with no visible eyebrows. His name is diagonally tattooed on his upper body, with "P" on his right arm, "AGE" on his chest, and "1" on his left shoulder. In his human form, he is shown wearing a horned bucket hat and a mask covering his jaw area, both being symmetrically bi-colored. He also wears a long-sleeved shirt and a cape. In his dinosaur form, he wears a pair of dark pants as well as a dark vest tied around his pants. He also wears dark gloves that go to his elbows.

Page One believes that anyone rebelling against the administration of Wano should be made an example of, and thus has no qualms about a powerful pirate like him being sent to deal with such instances. As a result, he is violent in his missions, destroying multiple soba shops while looking for Sanji and had no pity for the shop owners he wrongly attacked, viewing his actions as necessary to coerce Sanji into revealing himself. He is also very gluttonous, eating the soba from one of the shops he wrongly attacked, and decided to attack a fruit shop just because he felt like eating fruit. However, when together with the rest of the Tobiroppo, Page One seems to take a far meeker disposition, becoming flustered when his peers start looking down on him. In particular, Ulti seems to embarrass him the most with her personality quirks and overall disrespectful behavior, although he seems to still hold respect for her with the way he addresses Ulti as "big sis". As a Headliner in the Beasts Pirates, Page One holds a high position in his crew and has authority over the lower-ranking members. As a member of the Tobiroppo, he is among the strongest Headliners, with only Kaido and the All-Stars ranking above him.

Page One ate the Ryu Ryu no Mi, Model: Spinosaurus, an Ancient Zoan Devil Fruit that gives him the ability to transform into a spinosaurus. As a spinosaurus, he possesses tremendous strength, particularly in his jaws and tail, which are capable of effortlessly destroying buildings. In his hybrid form, his arms become long enough to use in combat and possess great strength as well, being able to overpower a kick from a Raid Suit-enhanced Sanji and send Sanji flying through several buildings. Page One and X Drake were sent to the Flower Capital by Queen to kill a soba stand owner named Sangoro. Page One then went on a rampage, attacking soba stands in search of his target. Sanji eventually came and attacked him, and Page One contacted his comrades to come to their location as he confronted the cook. Sanji donned his Raid Suit, and when Page One attempted to attack him, Sanji turned invisible and kicked Page One in the stomach.

Page One then transformed into his hybrid form and swiped at Sanji with his arm, overpowering Sanji's kick and sending him crashing through several buildings. Thinking Sanji was dead, Page One prepared to bring him to Kyoshiro, only for Sanji to drop down from above and attack him again. The outcome of the fight was not shown, but Sanji was able to escape the Flower Capital. On the day of the Fire Festival, Page One arrived at Onigashima with the rest of the Tobiroppo. They then sat down to wait to meet with Kaido and bickered amongst themselves. When Kaido arrived, he gave them the mission of finding his son Yamato, saying he would let them battle one of the All-Stars for their position if they succeeded. In the manga, the outcome of his fight with Sanji in the Flower Capital was not shown. In the anime, Sanji fled the scene after delivering a powerful kick but without leaving Page One incapacitated. Page One is named after the real-life card game of the same name. This fits with the card game-themed names of the Beasts Pirates' Headliners. Like X Drake, Page One has a numeral on his name and also tattoed on his chest.  In Page One's first manga appearance, his full beast form originally lacked his u-shaped eyebrow and had a more realistic appearance. In his first anime appearance, he is seen with his later design. 

Onigashima

Onigashima is a New World island and a region of Wano Country, which serves as the official base of operations for the Beasts Pirates, including the Yonko Kaido, the All-Stars, and the Numbers. Onigashima is a mountainous island that is very difficult to access outside the front gate, which connects directly to the sea, allowing ships to sail in. The waters surrounding the island are apparently lined with whirlpools that make navigating around it nearly impossible unless one utilizes specialized watercraft like a submarine. The island itself has a port where ships can dock. Notable structures in this port include a gigantic katana piercing the ground, water spouters that resemble oni faces, an enormous wagasa decorated with paper lanterns. The entrance to the port is lined with two statues depicting kitsune and a stairwell appears to connect the port to the interior of the central skull-shaped mountain. The torii is a small fortress located at sea, right in front of Onigashima.

It is heavily armed and serves as the first line of defense of the Beasts Pirates, having a number of the crew's soldiers stationed there.  The most notable landmark of Onigashima is a large rock formation resembling a skull with horns. This mountain appears to have multiple rectangular rocks on and around it, and is easily visible from a great distance. Based on the mansion's location, the skull's interior has a winter climate. Kaido resides in a giant mansion inside the skull-shaped mountain. Although it has yet to be shown in full, the mansion appears to occupy a considerable portion of the island's interior, being large enough to house the abnormally large top ranking members of the Beasts Pirates. Inside the mansion is a cell which was once occupied by Eustass Kid. According to the blueprints Kin'emon acquired from Ashura Doji, the mansion has a rear entrance accessible only from the back of the skull-shaped mountain.  According to Kin'emon, Minatomo built Kaido's residence.

X Drake and some other Beasts Pirates were outside Kaido's lair on Onigashima when they received news of Joker's defeat, which they tried shouting out to Kaido, unaware that he had gone to the Ballon Terminal. Sometime later, Kaido returned to his lair and received a call from Scratchmen Apoo, telling him they lost contact with Jack. Realizing his plans to take back Doflamingo had failed, Kaido drank a lot and suffered from intense mood swings, including a rage that caused him to hit some of his subordinates through the roof of his lair. Kaido received a call from Big Mom, who told him she would be coming to his territory to kill Luffy despite his adamant refusal. Back at Onigashima, Jack was scolded by fellow All-Stars King and Queen because the offerings from the Kuri region had been decreasing lately. After Queen captured Big Mom and brought her to Onigashima, Kaido and Big Mom met face to face and the two clashed until they decided to form an alliance to conquer the world. Around this time, the Numbers also return alongside Scratchmen Apoo to Onigashima for the Fire Festival. On the day of the Fire Festival, the Ninja-Pirate-Mink-Samurai Alliance commenced the raid on Onigashima. The Straw Hats reached the torii and defeated all the Beasts Pirates members stationed there.
