In episode 113, Mr. Stein uses this card during his duel against Jaden Yuki. After he summons this card, he uses this card and "Elemental HERO Burstinatrix" (who he took control of via the effect of "Scab Scar Knight") attack directly. Later Mr. Stein activates this card's effect to switch "Neo-Spacian Air Hummingbird" to Attack Position, so that Jaden would be forced to attack "Scab Scar Knight" with "Air Hummingbird". In the next episode, Mr. Stein activates the effect of "Scar-Knight" to destroy all monsters on the field and inflict 500 damage to all players for each destroyed monster, but Jaden activates "Cocoon Veil" to prevent himself from taking damage from the effect of "Scar-Knight". As three of Mr. Stein's monsters were destroyed, the effect of "Scar-Knight" inflicts 1500 damage to Mr. Stein, winning Jaden the Duel.
In episode 115, this card appears in Jaden's thoughts when he remembers Mr. Stein telling him that will be a time where he will understand what he is Dueling for and Mr. Stein telling him there has never been an instance where he has Dueled for himself.
This card also appears in a flashback Jaden has when he remembers Thelonious Viper telling him that all he needs to do is provide him with Duel Energy.
In episode 117, this card is shown in the remains of Mr. Stein's Deck when Jaden's friends arrive at the location where Jaden dueled Mr. Stein.
