BlackGaogamon is a Beast Digimon. Gaomon's physique has gotten larger, and its steadily growing claws are protected by gloves. "Black Digitron" was mixed in during its growth process, resulting in it taking on this black form. It is more resilient and takes less damage as compared to normal Gaogamon, at the expense of its speed.
- Dash Double Claw: Approaches the opponent at a speed it can't see, then fires off an X-shaped wave by slashing its claws.
Gaogamon resembles a large black Akita Inu dog with black nose and claws, fangs, yellow eyes, a gray belly, thick gold mane with braids, gray tail tip, feet tips, snout, inner ears, and a yellow cross-shaped mark in the forehead. It wears black belts and red and black boxing gloves on its front paws with its claws piercing through the the gloves, white bandages on its legs, and black ribbons on its back.
