Mask of Light and Mask of Darkness

Lumis and Umbra/Mask of Light and Mask of Darkness (光の仮面 Hikari no Kamen; 闇の仮面 Yami no Kamen) are members of Marik's Ghouls organization. They pride themselves on being an unbeatable tag team. By Marik's command, they challenge Seto Kaiba and Yugi Mutou to a Tag-Team Duel at the rooftop of a skyscrapper. In this duel, the glass panels that they are standing on each have a bomb attached to them. As soon as a player's Life Points drop to 0, the bomb will detonate sending the loser down a thirty-floor fall to his death (for the English version of the Anime, the bombs were changed to "Dark Energy Boxes" that would send the loser to the Shadow Realm before the fall).

Notable Dueling Cards

As their names suggest, they use a Mask-themed Lockdown Deck, that weakens and manipulates the opponent's cards while lowering their opponent's Life Points.

Note: For aesthetic quality, and since they only dueled once in the Anime series, their cards will be listed together.
