In the episode "Henchman," Marquis of Nuts appears briefly at the party Marceline plays music for. He does not seem to have particular interest in Finn bursting into the castle, indicating he may have moved past his grudge.
Marquis of Nuts has tan-colored skin and brown eyes. He wears a red cape, brown shoes, and a peanut shell as a mask (or armor). It is shown that inside his shell, he is just a single nut on the bottom half of the peanut shell. He carries a lance.
- Despite being the son of the Duke and Duchess of Nuts, he himself is technically a legume, not a nut.
