Bloody Eyes acts as the buddy monster to Dan Yamada. This white dragon insists he possesses a sealed power that must never be unleashed, claiming pursuit by a shady organization. His partner, however, dismisses these claims as false, indicating behavior typical of eighth grader syndrome (chuunibyou). He strongly dislikes any mention of his full soul name "†Dragonblood Eyes†" and frequently strikes dramatic poses.

Physically, he is a tall white dragon with golden eyes, prominent fangs and claws, and red and gold horns. Large red and purple wings extend from his back. Long black and red hair covers one eye, matched by blood-red brows and jawline. His attire consists of a sharp black overcoat featuring gold trims, purple inner lining, fur-tipped purple cuffs, and a dark red square-buckle harness. He wears black pants adorned with purple and red cloth wrappings, a red belt featuring a cross-shaped centerpiece, chain accessories, and a light gray abdomen plate marked with a red spiraling dragon symbol. In battle, he wields a red and black gun-blade weapon.

As a card, he belongs to the Dragon World with the Dragonblood Sect attribute. He has a size of 3, 10000 power, 2 critical, and 8000 defense. His ability activates upon being called by paying 2 gauge and placing the top three cards of the deck into his soul. When an opponent's monster is destroyed by card effects, he deals 1 damage to the opponent. At the start of the opponent's attack phase, he can select one of their standing monsters; for that turn, he nullifies that monster's abilities and forces it to attack him first if possible. The card carries the keywords [Double Attack], [Soulguard], and [Counterattack].
