Card Appearances:Umbral Horror Unform
- In episode 94, Vector uses this card during his Duel against Yuma Tsukumo (the Vector dueling was actually a clone used to fool Yuma as part of a convoluted plan). He Special Summons this card via the effect of "Umbral Horror Ghoul". Vector then overlays this card and "Umbral Horror Ghoul" in order to Xyz Summon "Number 66: Master Key Beetle".
