Taurus Fire

Taurus Fire, known as Ox Fire (オックス・ファイア) in Japan, is the combination of the characters Bud Bison and Taurus.

Mega Man Star Force
Taurus Fire was deleted in the first game. He comes back in a Station Comp Space.

Mega Man Star Force 2
Taurus Fire is unlocked from Bud's mind and is deleted by Mega Man. Bud's fan in place of Sonia Strumm, Amy Gelande is knocked out like a light. Yeti Blizzard is deleted by Mega Man. Omega-Xis notes that before Bud turns into Taurus Fire, some of Taurus' energy was still inside Bud, so he reawakened that power and that the Taurus Bud merged with was not the real one. It was a residual FM-ian (like Battle Network 5's Party Battle System image Data.)
