Alastor

An agent of the Jadow who uses the nicknames "The Midnight Thunder Boy" and "Blade Master." Although he was assisting the Jadow, Alastor is indifferent to their objectives, focusing instead on finding the ultimate battle, which allows him to be viewed as an "anti-hero" to some degree. He regards himself as Joe's rival, even while doubting Joe's methods. Alastor was also the one who gave Joe the inspiration for his "hero name." During Fire Leo's fight with Joe, Alastor held back Fire Leo as they both fell into the void surrounding Jadow headquarters, but Alastor promised to survive so that he and Joe could finally resolve their rivalry. He was supposedly created from the sword of Dante the Devil Hunter from the "Devil May Cry" series.
