Taurus (FM-ian)

Taurus known as Ox (オックス, Okkusu) in the Japanese version, is based on the constellation Taurus. He is an extremely strong armored bull with the bashfulness of a bull as well. He emits fire to propel himself forward or to burn his enemies. When he fuses with Bud, he becomes Taurus Fire; known as Ox Fire (オックス・ファイア, Okkusu Faia) in the original version. His seiyū is Nobuyuki Hiyama and his English voice actor is Neil Kaplan.

In Mega Man Star Force, Bud Bison tried to threaten Geo to go to school for Luna. Omega-Xis's brash personality causes Geo to punch Bud, leaving him embarrassed and his companions questioning their association with him, with Luna threatening to cut off their Brother Band, which Bud feels would make him a nobody. Taurus acts on his anguish, offering him the power to get Geo back. Under Taurus' control, Bud begins randomly destroying red objects in the real world. When he, Luna, and Zack go on patrol, they encounter Geo where Bud transforms and escapes into the cyber network of a truck that Luna and Zack are riding in, driving it recklessly through the city, attempting to run Geo over. Afterwords, Bud has little recollection of the incident, only that he did some terrible things.

Taurus Fire re-appears in Megaman Star Force 2 as a main story boss. Taurus' residual waves take over Bud during an eating competition and transform him back into Taurus Fire.

He also re-appears in Megaman Star Force 3 as a Wizard for Bud (apparently confirming that Bud has gained control over Taurus' EM body, or at least came into a mutual agreement), and as a Noise form that Megaman can change into. He is registered under the Satella Police's Project Transcode (A registry of those legally allowed to perform Wave Change) as No. 005. The reason why Taurus came here was by order of the FM-King to track down two criminals of planet FM that turn out to be Jack and Queentia's Wizards.

Anime History
In the anime, Bud grows jealous over Luna spending so much time with Geo upon his return to school, when Taurus (an FM-ian who is number one in terms of power amongst his kind) arrived upon sensing Bud. After being thrown into a hallway by Omega-Xis in the first confrontation, Taurus enters Bud's body and uses him as Taurus Fire until he is defeated and Taurus is forced out of him. Later, Taurus takes on the form of W Bud while gathering minus energy to recreate the Andromeda Key. He is the first FM-ian to be ultimately deleted by Gemini Spark in order to refill the real Andromeda Key with minus energy.

Manga History
In the manga, Bud encounters a gang of street thugs who bully him and an innocent puppy. Taurus subsequently targets Bud who desires the power to overcome the bullies. However, after being defeated by Mega Man, Taurus becomes an ally of Omega-Xis's and reveals that the "Star Force" will help Geo find his father.
