Card Appearances:Corrupted Keys
- In episode 94, Vector uses this card during his Duel against Yuma Tsukumo (the Vector dueling was actually a clone). After "Number 39: Utopia" attacks "Number 66: Master Key Beetle" and fails to destroy it due to the last effect of "Master Key Beetle", Vector activates this card to Special Summon three "Umbral Horror Mirage Tokens" that will always have the same ATK as "Master Key Beetle". After Vector activates "Umbral Horror Refresh" to restore the ATK of "Master Key Beetle" to its original value, the ATK of the "Umbral Horror Mirage Tokens" become 2500. Two "Umbral Horror Mirage Tokens" attack "Utopia", but Yuma activates the effect of "Utopia" twice to negate the attacks. A third "Umbral Horror Mirage Token" then attacks "Utopia". "Utopia" then destroys the "Umbral Horror Mirage Token" since the token wasn't a "Number" monster, but this allows Vector to activate "Umbral Horror Retaliation", which destroys "Utopia". On the last turn of the Duel, Yuma activates the effect of "Chaos Number 39: Utopia Ray V" to destroy "Master Key Beetle" and two remaining "Umbral Horror Mirage Tokens" with the help of the fourth effect of "V Salamander". Yuma then activates the final effect of "V Salamander" to inflict damage to Vector equal to the combined ATK of his destroyed monsters on the field, winning Yuma the Duel.
