Bio Volcano is a Raptor (Utahraptor)-type Zoid, one of over 200 species of biomechanical lifeforms depicted by TOMY's Zoids model, toy, and media franchise. The Bio Volcano is unique to the Zoids: Genesis anime and the related Genesis model line, and is one of the Bio Zoids used by the antagonists.
The Bio Volcano is a Genesis line Zoid, that features heavily in the latter half of the Zoids Genesis Anime. The Bio Volcano is heavily resistant to metal Zi and boasts a much larger arsenal of weaponry. The spikes and claws can act as blades, often effective enough stab through enemy Zoids or to block Metal Zi attacks. The blade mounted on its tail can damage most conventional Zoids with a single swing. It also has the standard flame cannon housed in its mouth. However, unlike other Bio Zoids, Volcano's cannon seems to be capable of a higher level of destruction.
One of the most prominent weapon that the Bio Volcano possesses is the Bio Particle Cannon. Housed underneath a sheath of crystals, the Bio Particle Cannon is mounted on the Zoids chest, not in the mouth as with most other charged particle weaponry. The Volcano does not need to clamp down while firing the cannon, it is seen acting much like the Geno Breaker in Zoids: Guardian Force, in that it can fire while in the air.
The Volcano is unique among Bio Zoids, in that it does not possess any silver armour. Instead, the Zoid is covered in a crimson variant of Bio-Armour.
As with all Bio Zoids, the Volcano only appears in the Zoids Genesis anime.
The Bio Volcano is piloted by Zairin, after his Bio Megaraptor is destroyed midway through the series. It was given to him by Jiin, the then ruler of Digald's military. Jiin, however, did not do this for altruistic purposes; instead, he had outfitted the Volcano with a device that sucked out Zairin's lifeforce, enabling him to complete his own Zoid, the Bio Tyranno. Zairin would be tormented by the Zoid, which not only caused him great pain, but would also spontaneously override his commands with automated instructions. It is only when he is taken to Sora City that the life draining device is removed.
The Volcano would prove to be an incredibly durable Zoid, and was found to be basically indestructible, even able to repel most Metal Zi weapons with ease. However, Zairin would not stay with Digald for the whole series, and defects upon learning the truth about the robotic Bio Raptor pilots (that they were run by people's extracted souls, one of whom was a friend of his). This rebellion would bring the Tyranno and Volcano into conflict, and, as it was the only other Zoid mounted with a Bio Particle Cannon, the Volcano would prove invaluable in Jiin's eventual downfall, both by destroying his Particle Cannon, and by exposing his Tyranno's Zoid Core.
The Bio Volcano can be seen in the game Zoids Battle Colosseum and Zoids Saga: Legend of Arcadia on Nintendo DS.
The Bio Volcano also features as an enemy (and later ally) in the game Super Robot Wars K.
ModelsBio Volcano was released as part of the Genesis Line in 2005. It comprised of nine frames; seven rubber armour, one for the tail blade and one for the 'caps' along with additional parts for the chest cannon, a brown "skeleton" base and a red pilot figure.
Bio Volcano's base skeleton is mostly pre-built and is very similar to that of its predecessor Bio Megaraptor, with some modifications made to accomdate Volcano's different armour and the chest cannon. Another most notable modification is the addition of adjustable ankles, allowing for better balance and range of poses and Volcano's sound set has also been modified to include sounds for charging and firing its chest cannon (Which in turn lights up)
