Beyblade: Metal Fusion

Tetsuya challenges Gingka on his terms

Tetsuya first appears in Metal Bey City, challenging Kenta and his friends to a battle and beating them using unfair means. He then challenges Gingka to a battle, but the challenge is declined due to Tetsuya's cheating in the previous battle. However, Tetsuya had this covered by keeping Madoka hostage, thus forcing Gingka to get into battle. Tetsuya loses the first round but by summoning crabs in the stadium, he is able to win the second match.

During the final battle, Tetsuya covers the stadium in mud, leaving Gingka at a huge disadvantage. Gasher remains unaffected due to its so-called "Special Spin track Change". During the battle Tetsuya, recalls his bitter memories of his friend, Echizen.

He explains, how he protected his friend from the strong Taraba by presenting himself for the battle. The battle covered his bey in scratches and also his heart, as he gets up to find Echizen missing. Tetsuya vowed not to trust anyone again and by using unfair methods he beat both Taraba and Echizen, leaving their beys in the same condition as his was and vowing to make all bladers suffer his pain.

Gingka tries to reason with Tetsuya but to no avail, but with a little help from his friends is able to figure out Gasher's weakness, Tetsuya threatens to harm Madoka. Just when the threat could work out, Madoka comes running to Gingka and Co., being saved by Benkei. Gingka then knocks Gasher out with his special move, Tornado Wing.

Tetsuya next appears in the very next episode, where he tells Hikaru about Gingka. When Kenta and Benkei are on their way to block Hikaru's path, Tetsuya gets in the way and launches Gasher at them. A battle between him and Benkei follows, which results in a loss for Tetsuya.

He also enters the survival battle, where he tries to force other bladers to pair up with him, however his plans are thwarted by Kenta, and he is beaten by the combined efforts of Kenta, Benkei, Takashi, Osamu and Akira, disqualifying him from the competition.

Tetsuya fails to defeat Gingka with his new Dark Gasher.

Tetsuya later spots Yu at a challenge match and follows him to the Dark Nebula. He convinces Doji to make his bey stronger, who remodels Tetsuya's Mad Gasher to Dark Gasher. With his new bey, he enters the same challenge match as Benkei and Gingka. He beats Benkei in the semi-finals by acting innocent and helpless and then striking with his special move when Benkei is confused (a technique he calls Operation O) (although he admitted he wanted to save that move for his battle with Gingka). In the finals he battles Gingka, but with Operation O not working against him, and Gingka aware of Tetsuya's weakness, Tetsuya falls to Pegasus's special move giving Gingka the win.

After learning about Gingka's points, Tetsuya decides to steal his points in order to earn himself a place in Battle Bladers and impress Doji by disqualifying him from it. He disguises as Nigel Crabcakes and runs away with Gingkas pointer. He is intercepted by Phoenix, who takes away the pointer and makes him flee. Tetsuya is punished by Doji for stealing Gingka's points by confining him to a room. However he is called out to battle Tsubasa, revealed to be a traitor now. During the battle Gemios' special move eliminates him from the battle.

Tetsuya makes it to the Battle Bladers, where he faces of against Kenta in Round-1. While he wastes his time boasting about a "Dark Move", he is knocked out before he realizes what's going on. He is forced to battle Ryuga and L-Drago due to this loss. Unable to match L-Drago's powers, Tetsuya is easily defeated and his spirit absorbed by L-Drago. His spirit returns to him after Ryuga is defeated and he is seen celebrating Gingka's victory in the final episode.

Dark Gasher's Track changes to 145 in height and the bey starts pecking at the opponent's. Gasher then leans over and goes in a position similar to Pegasus's Starblast Attack position.
