Sebastian Solace

Sebastian's body is shaped like a sea snake, elongated with light blue scales. He has a long tail.At the end of his body is a large tail fin. He has three arms. His hands are humanoid, but only have four fingers and are claw-like. Sebastian's face retains a humanoid appearance with fish-like features, such as an anglerfish esca on his forehead, fin appendages for ears, a fish-like mouth, and a third eye on his right side. He has short, wavy black hair.

Sebastian can be described as sarcastic, unpredictable and at times cruel. He has a deep hatred for Urbanshade due to their experiments on him, so he actively seeks to harm the company. Sebastian treats those who help him with respect, as shown in his various interactions. He does not consider the prisoners sent by Urbanshade his enemies and is willing to lend them an extra hand in exchange for their help.

In 2013, Sebastian was falsely accused of murdering 9 people and sentenced to death. Just before his execution date, Urbanshade captured him and faked his death, providing the government with a falsified execution report. He was then imprisoned as prisoner LR-P in Hadal Blacksite Prison. In early 2015, Sebastian was selected for an experiment designed to give humans fish-like gills so they could breathe underwater by experimenting with various DNA samples from deep-sea creatures. Although the experiment succeeded in giving him gills, it changed his appearance beyond recognition. Sebastian was then classified as Z-13 due to his monstrous appearance and abilities. Following the experiment, Urbanshade found no further use for him in human testing and reassigned him to underwater equipment maintenance. Seven months later,[3] Sebastian was found not guilty of the murders he was accused of. This information was not passed on to Sebastian, and he was not released from his imprisonment. By then, the mutation caused by Urbanshade's experiments could no longer be reversed, leaving him in his monstrous form forever. Sebastian was upgraded to MR-P, which granted him better living conditions, but he was still a prisoner.
