Kokoro is a 23 year old woman who is about 1,75 meters tall. She has long pink colored hair (natural hair color is brown) and red eyes. As a dieselborg she has a metallic skeleton covered by a synthetic pale skin. She is slender and kind of cute. Her teeth are sharp and pointy which makes even a friendly smile scary or a bit creepy.
Clothing: She wears a white round neck shirt, a black hoodie, a short red skirt, white socks, black and white sneakers and a black ribbon like choker.
Purpose: Security
Transformations: Her first transformation is where her right arm turns into a high velocity gun and her left hand turns into a metallic claw. Her limbs can extend to reach far object or to peek over obsticles.
In her second and full transformation she turns into a mechanical being with four metal legs, a chain gun below her body, two metallic claws which can rotate and a thruster underneath her to jump high or fly short distances. Her body is a mechanical suit of armor with two pistons moving at her sides and a metallic head with her face seemingly covered up to her nose by a metallic mask. Her head can split apart to reveal a top turret. In this transformation she makes a buzzing hydraulic sound when she moves.
