Inside the ring, Kid Muscle battles Checkmate, who suffers a sudden right knee swelling. Despite employing his ultimate muscle technique, Kid Muscle is pushed back by his opponent. Checkmate blocks an attack by merging into a chess piece form and body slams Kid Muscle. He then launches the boy into the air to execute his final move. However, the crowd's cheers revive Kid Muscle, who headbutts Checkmate's injured knee. This allows Kid Muscle to defeat Checkmate using the Kinniku Buster. Checkmate rises briefly before collapsing into scattered pieces, ending the confrontation.
