Inconclusive

Villains whose fates are left truly unknown because the authors are not making anymore stories, or the TV shows, movies and/or games were cancelled; this can also apply if the villain's fate was never properly disclosed or followed up on at any point later in the series.

NOTE: This category only applies when the story ended prematurely, not for when it was intentionally inconclusive (e.g. Mizuki and the Entity)

Some villains with unknown fates can also be Pure Evil as it can leave to unanswered questions as to how the villain(s) would have developed if the story was completed (e.g. SATAM’s Dr. Robotnik and Jolly Roger). Therefore, even for villains who are still alive and active and have not died/been slain by the time the story ends prematurely, they can still qualify if they meet all the criteria and meet such standards.
