Shattermaster is a Gronckle who was ridden by Dagur in Dragons: Race to the Edge. Dagur was hoping for a Skrill or a Night Fury, but was a bit displeased upon seeing that he'd be riding a Gronckle. In fact, he initially thought that Shattermaster was going to be breakfast for a more powerful dragon. However, he completely changed his mind upon seeing Shattermaster's abilities.
