"Dark Mummy" (ダークマミー Dāku Mamī) is an archetype of used by Baira in the Yu-Gi-Oh! VRAINS anime.
"Dark Mummy" monsters are Zombie monsters named and designed after medical equipment, such as syringe and cooper (although their names were localized in the official subs).
Baira utilizes her "Dark Mummy" monsters alongside "Virus" cards, allowing her to cripple the opponent's monsters while keeping her monsters at full power with the effect of "Dark Mummy Infuser".
