• In episode 70, Lumis uses this card during his Tag Duel with Umbra against Yami Yugi and Seto Kaiba. He equips this card onto "Shining Abyss", increasing its ATK by 1000. Umbra then activates "Masked Doll" so that he would not have to pay any Life Points to keep this card on the field. In the next episode, Umbra activates "Curse of the Masked Beast" to Tribute "Shining Abyss" and "Grand Tiki Elder" in order to Ritual Summon "The Masked Beast". This causes this card to be destroyed. In the following episode, "Rogue Doll" attacks Kaiba's "Blue-Eyes White Dragon". Lumis then activates "Mask of Weakness" to decrease the ATK of "Blue-Eyes White Dragon" by 700. Lumis then activates this card in order to equip it onto "Rogue Doll" and increase its ATK by 1000, but Yugi activates "Mystical Refpanel" to switch the target of this card to "Blue-Eyes White Dragon". As a result, "Rogue Doll" lost the bonus from this card while "Blue-Eyes" gained the bonus from this card. "Blue-Eyes White Dragon" then destroys "Rogue Doll". At the End Phase, "Blue-Eyes White Dragon" loses the bonus from this card's effect due to the effect of "Mystical Refpanel".
  • In episode 108, this card appears in a flashback explained by Leichter when he reminds Seto that his birthday gift from Gozaburo Kaiba was where all the mistakes made by Seto himself began.
  • In the manga, Mask of Brutality only increases the ATK by 700 points, and did not cost 1000 life points per turn.
