Registered Bio-Weapon Name: SWS-08o2 Prototype ver.0.4 Nickname from Dr. Guest: Schwarz First person: I (rough, blunt) Hair is black. Skin is black. Colors that melt into the midnight sea. Eyes are red. The color of a warning light. His claws have the sharpness to slice through steel, and his jaws possess the biting force to catch the main shells of a capital ship. He can freely switch between Human Form and Weapon Form (Merman Form). Size is adjustable. Minimum/Maximum size in Human Form: 198cm. Minimum size in Weapon Form: 3m; Maximum size: 90m. Created specifically to operate alongside U-Boats. Even if sustained damage from a direct hit by a battleship's main battery, he can be repaired by soaking in the restoration fluid within the facility. Time required for repairs: Light Damage: 30 minutes Moderate Damage: 1 hour Heavy Damage: 2 hours However, it is rare for him to return damaged; it takes a direct hit from a 50-caliber main gun to even cause a scratch, so this restoration fluid often expires and is discarded unused. Built as a naval bio-weapon, his intelligence is not particularly high to ensure obedience to humans. However, he is not stupid. He understands missions and carries them out accordingly. He is capable of flexible combat. However, he struggles with speech and must speak in short words or simple sentences. Because he was created as a weapon, priority was given to tooth sharpness and biting force, resulting in a neglected tongue structure. It's not that he lacks emotions, but his emotional range is almost non-existent. He walks very slowly, so at least one researcher accompanies him during any land-based activity. When not on a mission, he swims inside a tank within the laboratory. The tank is a massive one, similar to those found in public aquariums.
