Rebonack appears in two episodes of Captain N: The Game Master, however he is referred to as Iron Knuckle in the series. He is first shown in "Quest for the Potion of Power" after Link, Princess Zelda, and Kevin arrive to the chamber of the Potion of Power in Island Palace, where Iron Knuckle reveals himself to be the guardian of the potion.[4] Iron Knuckle rides an armored horse, but it does not float, instead moving about on four legs. Link and Kevin argue as to how they should go about defeating him,[5][6] and before they even manage to inflict damage upon the armored foe, Princess Zelda is taken by Iron Knuckle and Link realizes that he must fight alongside Kevin to be able to defeat it.[7] Together, Link and Kevin fire at Iron Knuckle, causing its horse to disappear and giving Zelda a chance to free herself. The three heroes then shoot at him one more time to finally defeat it.
In "Having a Ball", another Rebonack/Iron Knuckle confronts Link, Princess Zelda, Kevin, and Princess Lana while they are exiting the tunnel that leads to the Island Palace. Kevin tries to shoot it with his Zapper but it has no effect, so the group jumps out of the way and allows Iron Knuckle to charge past them and fall into a nearby lake where it sinks along with its horse.
