The Hooper trooper is a recurring monster in the Dragon Quest series, first appearing in Dragon Quest XI. It is a big blue demon that spins a spiked hula hoop around itself.
Hooper troopers are rotund demons with pale blue skin and big bellies known for the golden spiked rings that they constantly spin around with their bodies. They have tiny yellow eyes with black irises, pointed ears, a pair of curved purple horns on their heads, and a maw filled with sharp fangs and a blue tongue. The lower halves of their bodies have digitigrade legs like that of a faun or satyr covered in purple fur and they have long tails with a pair of golden rings near the ends. On their hands, they have pointed purple claws which they have a chance to drop after battle. The demons wear purple collars with blue triangular designs around their necks, yellow and purple sashes around their waists over ragged blue cloth, and they also wear various golden rings around their arms. They are able to cast powerful explosive magic and use their trademark golden hoops to send out whirlwinds that can rip apart their opponents.
These merry monsters have complete mastery of their spiky hoops. As they happily hula away, rapt in their ringed recreation, they never seem to notice the devastation left in their wake.
