Alastor  

The Midnight Thunder Boy

The Midnight Thunder Boy and Blade Master is an agent of Jadow who uses these nicknames, but his true goal isn't aligned with Jadow's. Instead, he seeks out ultimate battles, making him somewhat of an anti-hero. He sees himself as Joe's rival, even though he questions Joes methods. Alastor was the one who gave Joe his "hero name" and during their fight with Fire Leo, he restrained them both before falling into the void surrounding Jadow headquarters. It is said that he was created from the sword of Dante the Devil Hunter from the "Devil May Cry" series.
