Card Appearances:Magical Tomb
- In episode 94, Vector uses this card during his Duel against Yuma Tsukumo (the Vector dueling was actually a clone). He uses this card to select Yuma's "Rank-Up-Magic Limited Barian's Force" and seal it up, preventing Yuma from using it. Vector then activates the second effect of "Number 66: Master Key Beetle" to prevent this card from being destroyed by card effects. Later "Number 39: Utopia" attacks "Master Key Beetle" (whose ATK was 0 via the effect of "Gagaga Girl"), but Vector activates the final effect of "Master Key Beetle" to send this card to the Graveyard and prevent "Master Key Beetle" from being destroyed by battle. On Yuma's End Phase, this card's final effect adds "Rank-Up-Magic Limited Barian's Force" to Yuma's hand.
