Mad Gasher CH120 SF

Mad Cancer/Mad Gasher is a balance-type beyblade that used to belong to Tetsuya Watarigani. When he decided to join the Dark Nebula organization, Doji had it remodeled to make it more powerful and turned it into Dark Gasher. Its special move is Six Crab Sea King. At first, he thought that with his new bey, Dark Gasher, he could defeat Ginga Hagane, but his hopes failed him as Ginga still defeated Tetsuya Watarigani and Dark Gasher.

Dark Gasher also had a battle in Battle Bladers but got knocked out in the first round.
