Background
Gruff caught the X-Virus like everyone else and he coughed out Xruff. Xruff tortured him and flew away to join Nightmare. Nightmare let him in his army and they started to fight Flywish. He often loses to Flywish but is the strongest puffle. He can even beat up Jenni. He fought many good guys. He, like Gruff pranks puffles but pranks them evily. He often pretends to be Gruff to vandalize Flywish's Mansion. He ends up being defeated by Flywish but sometimes defeats Flywish. He also once beat up Jenni X which caused him to get zapped by Gregory

Trivia
