Hotburples strongly resemble their Gronckle relatives, although they have a larger body and wings, as well as their eyes being positioned closer to the snout than to the ears. Hotburples also appear to have a larger tail bludgeon and a slightly smaller jaw, but with sharper and smaller teeth compared to Gronckles. Like Gronckles, Hotburples have tough body scales and hard bumps all over them.
They might have the personality of a really lazy cat, which is opposed to Gronckles, which have a bit of a bulldog like personality. They have a high appetite for minerals and iron, but mostly scraps. Hotburples' have a usually laid back disposition, but are not to be messed with as shown in their debut episode.
Despite this, they can be incredibly aggressive and hostile if faced with a crisis. This can be displayed when Grump, the supposedly docile and tame dragon, attacked the Dragon Hunters to save Gobber.
- The official measurements given by DreamWorks Animation do not appear to be realistic when considering the relative sizes the viewer sees within the Franchise. Based on the Model Sheet for the Hotburple, this dragon should have a Wingspan of 31 feet and 5 inches.
- Since Hotburples are very similar to Gronckles in terms of appearance, behaviour and abilities, it is likely that the two dragon species are from the same family, just like the Night Fury and the Light Fury.
