Sebastian(Z-13)

Sebastian's body is shaped similar to a sea snake, in that it is elongated and covered in blue scales. At the end of his body is a large tail fin. Sebastian's skin is light blue. His torso is humanoid, with two large arms and one smaller arm on his left side. Sebastian's hands are humanoid, although he only has four fingers with claw-like ends. Sebastian's face retains a humanoid face (which is mostly always smiling) with fish-like features such as anglerfish bulbs on his forehead, fin appendages on his head, sharp teeth, a fish-like mouth, and a third eye on his right side. He also has a gold/yellow ring on his pinky (lower left hand). In the game, Sebastian wears a dark brown jacket with a white tank top and a white tie. He also wears various belts and accessories, such as a holster with a pistol, a portable hacking device, an armband on his smallest arm, a bandolier, and a small pin with a photo of a cat. Sebastian has several pouches on his tail, which contain supplies that he sells to the player! Sebastian runs a makeshift store, where he sells items and supplies to prisoners in exchange for any research they carry. He also supplies the player with items through Dead Drops, asking for Crowns in exchange for items to be dropped off at the Submarine Dock. Sebastian does not consider the prisoners sent by Urbanshade to be his enemies, and is willing to help them in exchange for their help. The more times you leave and enter his store, the more annoyed he becomes, eventually kicking you out. Sebastian can also be seen when the player is looking at Documents, as he is the one who shows the documents to the player. He often responds with sarcastic or comedic comments about each monster. Interestingly, Sebastian is forbidden from showing Mr. Lopy's document. As of the Friendly Fire update, Sebastian is capable of harming/killing the player if they send him a Flash Beacon.

The first time Sebastian uses Flash Beacon, he will growl and pick up the target player before warning them "Don't do that again." Sebastian will then break the player's Flash Beacon before throwing them to the ground, dealing 50 DMG. If any player chooses to send his Flash Beacon again, Sebastian will instead pull out a gun and shoot the target player, killing them instantly. He will also tell the target player that he warned them and will not show them the document he has on him. According to his document, his first appearance in the Pressure Timeline is in 2013, where he was accused of killing 9 people and was sent to be executed in the electric chair. Before this happened, Urbanshade "caught" him by sending a fake execution report, causing Sebastian to be declared dead. In early 2015, he, now an LR-P rank prisoner, was selected for an experiment to transfer gills into humans. He was tested with DNA from a female anglerfish, ███████, a blue whale, a great white shark, a silver backfin, a mantis shrimp, and a sea snake. Although the experiment was a success, the side effects were massive, as in Sebastian's current form. There was a chance to reverse the physical damage done, but it was not necessary due to his low rank. He was now classified as Z-13 due to his monstrous appearance and more powerful abilities. Later in 2015, Sebastian was found innocent, as he did not kill the 9 people he was accused of. However, Sebastian was not told of this information and was not released to the public. The side effects were now impossible to reverse, but his rank was changed to MR-P - which granted him better living conditions. Sebastian Solas, also known as Z-13, "The Tinkerer", "The Saboteur" or simply "Sebastian", is a major character in Pressure, serving as the player's ally in their adventures in the Hadal Black World.
