  • Withered Sprout is the only monster in the series to officially be named three different threat levels.
  • He was first considered to be Wolf, due to his cowardly nature and weak looking appearance.
  • He was considered a Tiger by the Hero Association after being defeated instead of a higher threat level in order to prevent "destroying the balance of the pro hero world".
  • He was suggested and considered to be a Dragon level by a Hero Association staff member and Smile Man, but not officially registered as one.
