I swear, this guy's the "Ed the Hyena" of the dragon teens. (Image by thesharp0ne)
"Fizzle" is a teenage dragon paling around with Garble. While canonaly, he doesn't have an offitcal name nor is it ever likely we'll canonly see Garble and crew again, it's been known that his name is "Fizzle", (or at least based on the Villain Wiki page in the image gallery in Dragon teams.). Fizzle is the white dragon who is the "oddball" of the dragon teens and is known for obcessive chuckling like a loony bin reject and a master of pranks. His obedience to Garble lead him to become a traitor to Equestia and all of dragonkind when he and the other teens joined Team Nefarious, and still to this day. The first ever involvement with Team Nefarious concerns The REAL Best Night Ever, and according to Discord's Dilemma, dispite the first outing's failure, it's clear Garble and the teens are still involved with Team Nefarious.
