Warrius Zero ウォーリアス・ゼロ

He is a commander of the independent Fleet, what remains of the armed forces of Earth. The war against humanoids left him without family and now his only motivation is to fight the mechanical men, but he receives an order from the supreme commander: to hunt a space pirate called Captain Harlock, who is said to be allied with the mechanical men. Zero faces a difficult situation, as Harlock was the one who trained him and he only assaults the ships of the mechanical men. Determined to find the truth, Zero accepts the mission. (wikipedia)
