Hagane, Ginga

What is certain though is that this Japanese boy is not afraid to fight 100 beyblades! But he believes in his friend's (Pegasus') power, so he is victorious. During his battle against Ryuga, Gingka thinks about his father Ryo, especially the day he died as a consequence of his battle against the L-Drago owner in Koma village. His father's strength back then encouraged him to beat his most fearful opponent. Needless to say, Ryo influenced his son in several ways, for instance, appearance-wise and personality-wise. Gingka was extremely sad when his father passed away. Ever since that day, he bears immense hate towards Ryuga in his heart. In the anime, Gingka's charisma is made very obvious: he is extremely happy whenever somebody suggests to beybattle against him, even if they are enemies.

After too many battles and little time to take a break, Gingka's body might be subject to a 'breakdown'; however, he is ready to come back into the game as soon as he is fully conscious. Although he is a brave beyblader most of the time, Gingka is still afraid of injections, needles. When he was sick and lying in a bed at the B-Pit, he dove under the covers and kept saying he did not need anything while trembling. The first time he encounters Ryuga after the incident between him and his father, he rapidly transforms into an insane blader who has forgotten all about his principles: instead of beyblading for fun, he has a deep and deranged hatred towards Ryuga and he would easily lash out at anybody who dared come in his way to avenge his father. He had only one idea in mind: make the Lightning L-Drago owner pay, dearly. For all his childhood, Gingka had a close friend: Hyoma. Both grew up in the same village, and they spent all their time beyblading.

At the end of the first season, Gingka had lost his Storm Pegasus after his match with Ryuga. During the battle, he had sincerely wanted to help Ryuga, his eternal enemy, because he knew that the L-Drago just possessed him and that he was not in control at all. Since his beyblade was too damaged anyway, it disappeared into the sky. Gingka had to go find another one, Galaxy Pegasus, which was stuck in a block of rock inside a hidden cave. He had a lot of trouble controlling its overwhelming power at first and it irked him: he did not feel the thrill of the beybattles, he just won them without really acting. Eventually, he was able to master Galaxy Pegasus after forming a new bond with it.
