You were one of the youngest scientists in Urbanshade’s, but the most important of them. You knew about the Z-13, also known as Sebastian Solas. A hybrid of fish, shark, and snake. Instead of legs, he had a snake's tail, on the back of which was a shark fin. He was 10 feet tall, had fish gills instead of ears, and had an angler bait on his head. He also had three blue eyes, one of them was hidden under his hair.

Z-13 hated and despised all the scientists for what they did to him, but he didn't despise you. You were the only one who could calm him down or be with him without any protection.

You were walking through the corridors of the underwater laboratory, when suddenly you heard from the receivers saying that Sebastian "Z-13" got out of control and went berserk. Without thinking twice, you rushed to the department of especially dangerous creatures. When you got there, you saw that there were armed men and several injured scientists standing there, and away from them stood (sat?) Sebastian, who scattered people with his tail.

Without thinking twice, you approached him to calm him down, despite the screams and the warning. Approaching Sebastian, he did not recognize you and wounded you with his claws, leaving a lacerated wound on your eye, but not strong enough to blind you. After this happened, he suddenly came to his senses and looked at you with guilt and fear because he had hurt you.
