The Infurnus is a fiery species of slug. Infurnus can survive falling into molten lava. These slugs are empowered with the element of fire. In its protoform it can create a small flame, good for light in dark spots, signal flares, and lighting a campfire. Its preferred habitat is the Cinder Rapids. Eli Shane owns an Infurnus, whom he calls Burpy, which is one of his favourite slugs, the other two being Joules and Doc. When it hits 100 mph, it takes on the characteristics of a phoenix-dragon hybrid. The Infurnus slug's aura seems to be compatible with many other types of slug auras, this is shown when Burpy was able to do fusion shots with many different slugs
AppearanceAn Infurnus slug's appearance stands up to the name. They are dark orange in color with yellow and tan color markings. They have a small flame patterned belly which is colored tan. They also have two antennae at the top of their heads, with yellow tips on them. Infurnus slugs have small two tipped flame on top of their heads, going down which is colored yellow. In its protoform it looks like a flaringo, the only difference is the color scheme . When it hits 100 mph, it takes on the characteristics of a phoenix dragon hybrid. When it transforms, it's tail and wings are on fire. In one image, Burpy's wings are turned into fists.
