As of now I think the new dragons are Gauntlet-specific, since they do not appear on the Brawl dragon list.

These are the boss dragons I noticed appeared throughout the Gauntlet event:

Meatlug (?), Flystorm, Defender Whispering Death, Lil Lullaby, Dark Eclipser, Irontooth and Spikeback.

Besides Gauntlet bosses always appearing to be in between level 16 and 19, I noticed they share the same abilities as other preexisting Brawl dragons, which draws the conclusion that they are simply enlarged reshades of the same dragons. Also, even though they share the same abilities, none of the Gauntlet bosses demonstrate that cinematic effect which elaborates their special ability. Based on observation these are the Brawl dragons that share the same ability as the Gauntlet bosses listed in the same order as they appear throughout the event:

Meatlug = Gronckle

Flystorm = Edge Nadder

D. Whisper Death = Exotic Whispering Death (If I remember correctly)

Dark Eclipser = Champion Triple Stryke

Irontooth = Lump

Lil Lullaby = Thunderdrum

Spikeback = Champion C. Quaken
