Ginkai is a Medafighter who appears in Medabots Spirits. Ginkai is a wide boy, always wearing red and brown clothes. Having spent almost all his life without any friends, he can't stand it. His attitude is that of a bully, always acting violently and willing to cause riot with his Kilobots. However, this changes later in the series, when Ginkai recivers his trust in Medabots and is willing to fight alongside them. He is stubborn, a glutton, honest, brave and has a heart of gold, but can be jealous.
