- In episode 138, Mizar uses this card during his Duel against Don Thousand. He Special Summons this card and "Schwarzschild Limit Dragon" through the effect of "Galaxy Stealth Dragon" (which was activated twice). Mizar then activates "Dragon King's Demise" to Tribute all his Dragon-type monsters and inflict their combined ATK as damage to both players, but Don Thousand activates the second effect of "Numeron Network" to activate "Numeron Spell Revision" from his Deck, negating the effect of Mizar's "Dragon King's Demise" and activating "Card of the Dragon King" instead. Due to "Card of the Dragon King", Mizar is forced to Tribute his Dragon-type monsters, inflict their combined ATK as damage to himself, and draw one card for each Dragon-type monster Tributed, winning Don Thousand the Duel.
