The Special Circuit badge is a dragon, according to the belt and canvas.
To get to the Special Circuit, you must complete the Minor, Major, and World Circuits without losing a single match. If you are knocked out, you need to start the circuit all over again. The circuit is extremely challenging, containing boxers with very tricky move sets.
The Special Circuit consists of 4 Fighters: Narcis Prince, Hoy Quarlow, Rick and Nick Bruiser. After beating Nick Bruiser, the end credits will roll, showing all the fighters the you have beaten. At the end of the credits, it will show a screen of Nick knocked out and Little Mac in the pose for when he beats the champ of a circuit saying one of his lines based on his final win/loss record.
- Nick Bruiser, the champion of Special Circuit, has once lost to Glass Joe by accident.
- This is the only circuit in Super Punch-Out!! with one or more characters who aren't a palette swap of any character. These characters are Narcis Prince and Hoy Quarlow.
