WHAT WE KNOW: Unproduced Direct to Video/DVDEdit
According to Steven E. Gordon's official website, Batman: Asylum "went into development after Batman: Subzero and was intended to be a Direct-to-Video also. The producer, Boyd Kirkland, convinced WB to let us re-design all the characters. This was my first time I got to professionally design a "super-hero" show. Unfortunately WB decided to cancel the project and do a DTV Batman Beyond instead."
