Toothless is the Night Fury at the centre of How to Train Your Dragon, first released in 2010, and his roar has become one of the franchise's most recognisable sounds. Clips from the first film circulated widely online as fans edited dragon scenes, reaction videos and fantasy montages. The sound still works because it is tied to a beloved character rather than a generic creature effect, so listeners recognise it instantly even without seeing Toothless on screen. That instant recognition keeps it popular for edits, memes and gaming moments.
