Midnight Man

Anton Morgart was a professional art thief whose trademark was that he would always strike at midnight. After being shot by a rubber bullet from Marlene while fighting Moon Knight on the roof of his New Jersey mansion, he falls into a river which deposits him in the sewers. He later captures Steven Grant's butler, Samuels, to lure him into his hideout in the sewers to settle his score with him. It turns out that he is working with Raoul Bushman, who ends up betraying Morgart and leaving him, Samuels, and Spector to die in the flooding sewer system. However, Spector rescues Samuels and Morgart.

In the Marc Spector: Moon Knight series, Morgart's son Jeff Wilde becomes the sidekick of Moon Knight as Midnight.
