• In episode 84, Shark uses this card during his Duel against Yuma Tsukumo. He equips this card to "Black Ray Lancer", which increases the latter's ATK by 400 and treats it as a "Shark" monster (this was done so that Shark could use the effect of "Shark Fortress" on "Black Ray Lancer" later in the turn). This card remained on the field until the Duel was over.
    • While Black Ray Lancer was equipped with this card, Shark referred to it as "Black Shark Lancer" (intentionally).
