Averal is a purple and green general-class snake, created when a purple Venomari viper was mutated in a laboratory. As a result of this, he has a different power than other Serpentine: he can move very quickly, is remarkably strong, and can create electric shocks. He is one of Terven's most important allies and is his brute force man, or rather, brute force snake. He uses a large dagger as his weapon of choice.
His vehicle is a truly gigantic purple snake tank. This vehicle is equipped with twin venom mortars and one frontal laser cannon, of which the beam is focused by crystalised venom. It utilizes an energized version of crystalised venom as it's power source. Of course it is covered in snake-skin patterns. It has a place for three Serpentine and is mentioned in Terven's Story.
