The King one, and the OG Kremling Krew. The pirate one might follow the theme nicely since everyone is dressed like a pirate, but king is my favorite look of his and it fits his personality the most, and I enjoy the military outfits on Klump and Krusha. I wouldn't mind them sticking to his King form since I can't really imagine them coming up with a better disguise than the ones he already had.
