Brute Skrill looks very different from other Skrills. Its body is mostly bronze with red and emerald on its wings. It has an emerald belly. It also has emerald around its eyes and red around emerald.
It is the first Skrill that doesn't have a dark coloration, with the second being Hunterbolt.
According to its description, the Green Death fought to have this dragon. This can be interpreted in one of two ways: either there is another Red Death the Green Death had fought with, or the Green Death fought with another Alpha Dragon.
