Masamune Kadoya

is a recurring character and a former member of Team Gan Gan Galaxy in the Metal Saga. His tag-partner was Gingka Hagane in Big Bang Bladers and his current Beyblade is Blitz Unicorno 100RSF while his old one was Ray Striker D125CS. He is currently living in America at the Beyblade GYM with friends, Toby and Zeo Abyss.

Masamune is the self-proclaimed #1 Blader in the World. He is very persistent and willing to never give up when challenging a Blader like Gingka. With this, he can get cocky but is very confident in himself and willing to try anything to become the best Blader.

Character Design
Masamune has black hair with white highlights and a red hair sticking out, brown eyes and light skin. He wears a green sweatshirt with trim of sky whitish blue and has a trim of dark blue for pockets and a line on his jacket arms, an orange shirt that has two parts sticking out of his jacket, khaki shorts with lightning shaped lines going down the seams as a reference to Ray Striker's Special Move, and brown gloves. He also wears green shoes with white socks. He looks a lot like Ryuto.

Personality
Masamune is the new bottom of Gingka, who will eventually join his side like Kyoya did. He is a small kid, but he has a lot of guts. He follows Gingka wherever he goes to challenge him continually, losing almost everytime. Gingka and him often get into arguments over ridiculous things like the other's courage, or lack of courage. They will eventually pair up, with Yu and Tsubasa, to represent Japan in Big Bang Bladers. Masamune had previously not been able to participate in Battle Bladers.

He is very persistent due to the fact that he would follow Gingka around and carry on battling him and is very confident. Masamune has little self-restraint: if he disagrees with something, he will really not hesitate to say so, and he will be overly visual about it, shaking his arms around to illustrate his anger.

In battles and in practice, Masamune will never give up and keep working harder. His number one goal was to defeat Gingka, and he never stopped challenging him until he beat him. Afterwards, Gingka became better at controling Galaxy Pegasus though, and Masamune rejected his offer for a rematch after he saw how powerful the other's Beyblade was though.

Beyblade: Metal Masters
Masamune had a history with being taught by Faust, the Twisted Blader. Masamune's' early relationship with Gingka started with a competetive attitude and developed into a friendship. Masamune was once obsessed with being the number one Blader, he eventually humbled himself.

In Seeking the Legend, Masamune boarded a plane to a tournament in order to find Gingka and defeat him but Gingka was not there. He later found Gingka after Gingka obtained Galaxy Pegasus and challenged him to a battle.

In The Persistant Challenger, Masamune had his battle with Gingka but lost. He then battled with him numerous times, yet still losing. He made friends with Kenta and challenged Gingka yet again, but still lost. Little did he know that Chi-yun Li was spying on their battle.

In A New Challenge, Masamune and Gingka recieve a challenge for a tag-team battle from Chi-yun Li and Mei Mei, two Bladers from Team Wang Hu Zhong. Masamune and Gingka have a hard time battling as they keep arguing, thus Chi-yun Li and Mei Mei gain the upper hand. However, they both set aside their differences and manage to win the battle. Chi-yun Li and Mei Mei then tell them of a world Beyblade tournament, which excited both Masamune and Gingka.

In The Beylin Temple in the Sky, Team Gan Gan Galaxy traveled to China in order to gather information on their rival team, Team Wang Hu Zhong. There they found Team Wang Hu Zhong and visited their Beylin temple, a temple designed to train the strongest Bladers in China. They met Wang Hu Zhong's leader, Da Shan Wang but a member of their team was absent. Da Shan Wang put Masamune and Gingka through some tests to see how powerful they were. After that, Da Shan challenged Gingka to a battle which he accepted. Da Shan's Rock Zurafa was absorbing Galaxy Pegasus' attacks, potentially giving him a loss. Just when Gingka was to attempt his Starbooster Special Move, Masamune launched Ray Striker which abruptly, ended the battle as a draw. Masmaune then explained to Gingka that he sent out Ray Striker because Wang Hu Zhong was spying on them to see the Starbooster Special Move, as no one else has seen it.

Masamune reunited with his teacher,Toby and at the end of Beyblade Metal Fight Explosion and with his peer, Zeo Abyss at the Sprial Core weapon. The three Bladers together returned to their old gym to continue their work.

Metal Fight Beyblade 4D
In Lynx, The Mysterious Cat, Masamune is stunned and rather jealous at the fact that Ray Striker didn't "evolve" like Big Bang Pegasis did when Gingka shows him.

Masamune reappeared in Rebirth! Team Dungeon where he was training to become a Legend Blader. He was unable to battle due to renovations to his bey.

In Finished! The New Unicorno, Masamune recieved his newly renovated bey, Blitz Unicorno 100RSF, Just in time for his battle in the Sphere 360 tournament. With the new power inside his bey, he qualified for the Finals of the tournament alongside King and Jigsaw.

In I Am The Champion!, Masamune faced off against King, Jigsaw, Zeo, Toby and Tsubasa in the finals of the Sphere 360 tournament. After a long fight, in which the stadium collapsed and rolled into the sea, he placed Second losing only to King and his Variares D:D.
