S-Snake

S-Snake, a Seraphim and clone of Boa Hancock, serves as a supporting antagonist in the Egghead Arc. She shares a resemblance to both Hancock and the adult Kuja, possessing brown skin, black wings, and white hair, as well as star-shaped pupils. S-Snake is significantly larger in size than her childlike appearance, and has a tube filled with Green Blood replacing a section of her right upper arm. Despite being a Pacifista, S-Snake expresses a considerable amount of personality, becoming flustered when praised and feigning vulnerability to make opponents drop their guard. 

 

She also uses her cuteness to charm opponents and make effective use of her abilities. As with all Seraphim, S-Snake is obedient to the Pacifista authority hierarchy. Weeks later, when CP0 infiltrates Egghead to kill Vegapunk and his satellites, S-Snake is deployed alongside S-Hawk and S-Shark under the command of Sentomaru to combat the threat. While Luffy and Lucci fight, the three Seraphim meet up with Sentomaru and assist the Straw Hat Pirates in fleeing with Vegapunk. They are later joined by S-Bear and commanded by CP0's Pacifista authority chip to cease their attack on the agents. When CP0 infiltrates Egghead's Labohase, the four Seraphim follow the assassins and are ordered by Lucci to destroy Vegapunk's laboratory. After damaging the building's structure, they cease their attack on Edison's orders. In a separate incident, S-Snake attacks Pythagoras during his search of the third floor of building C. After partially petrifying Franky and York, S-Snake charms Lilith and Usopp before petrifying them as well. However, Franky manages to immobilize her with Lilith's bubble gun.

S-Shark

S-Shark is a member of the Seraphim and is actually a clone of Jinbe. Although he resembles a child version of Jinbe, he is a large whale shark fish-man with short hair, webbed hands and feet, fangs, and star-shaped pupils. In addition to his fish-man traits, he also has Lunarian characteristics, such as brown skin, black wings, and white hair. S-Shark's right forearm has been replaced by a tube filled with Green Blood, and like the rest of the Seraphim, he has "PX-" on his chest.

S-Shark hasn't displayed much of a personality outside of his aggression towards the Straw Hat Pirates and his obedience to Vegapunk's commands. He was put to the test when Lilith, Pythagoras, and Edison had him battle Sanji, Nami, Usopp, Robin, and Franky simultaneously, but Shaka intervened and ordered S-Shark to stand down. Later on, S-Shark was deployed with S-Hawk and S-Snake under Sentomaru's command when CP0 infiltrated Egghead to kill Vegapunk and his satellites. During the attack, S-Shark and the other Seraphim were instructed to hold back CP0 while S-Snake assisted the Straw Hat Pirates with fleeing with Vegapunk. However, after Sentomaru succumbed to his injuries, the Seraphim followed CP0's command. When CP0 infiltrated Egghead's Labohase, S-Shark and the other Seraphim followed the assassins and were ordered by Lucci to destroy Vegapunk's laboratory. S-Shark used a beam attack on Edison, but it was unsuccessful, and the Seraphim stopped their assault.

S-Bear

S-Bear is a clone of Bartholomew Kuma and one of Vegapunk's greatest achievements, known as a Seraphim. In the Egghead Arc, he plays the role of a supporting antagonist due to his obedience to a Pacifista authority chip holder. Physically, S-Bear resembles a younger Kuma with longer hair and an outfit reminiscent of the current Kuma, bearing an emblem associated with Vegapunk's creations. 

 

As an artificial lunarian, he possesses brown skin, black wings, white hair, and white ears. S-Bear's abilities are formidable, with tremendous resilience as a lunarian, the ability to fire lasers from his mouth or the palms of his hands, and artificial paws that harshly repel anything they touch. S-Bear was taken away from Egghead on a mission, and when CP0 agents attempted to return him to the island, they were secretly on a mission to assassinate Vegapunk. Lucci planned to use S-Bear's Nikyu Nikyu no Mi ability to infiltrate the island. However, Sentomaru intervened and had S-Bear attack the government agents instead. The Seraphim later followed CP0's command to attack Vegapunk's laboratory, but ceased their attack when ordered to by Edison. During the search for the missing Stella within the Labophase, S-Bear and S-Hawk targeted Kaku and Lucci while they were restrained and unconscious. Despite Shaka's attempts to stop them, the two Seraphim continued their attack.
