King Chomp is a robotic Chain Chomp created by Drill Finger. It is the true boss of World 4 in the Super Mario Galaxy 2 Longplay and can fly. It possessed Bowser and made him ultra powerful. After Bowser flew away, King Chomp plummeted to the ground all banged up and exploded. Despite his name he's not a Chain Chomp he's just a robot in the design of one.
