(Doctor Strange: Sorcerer Supreme I#6/2) - After World War I, feeling humiliated by Germany's defeat, and seeking revenge, Viscount Heinrich Krowler turned to the Dark Arts. However, he soon realized that his own abilities, while considerable, would not be enough to guarantee him the triumph he sought. He discovered that, through a Ritual of Transference, he could acquire greater power, but only from one of his own bloodline. He therefore arranged for the marriage of his daughter, Sara, to Nikolai, the First Baron of Mordo. From that union was born a son, christened Karl Amadeus -- the Baron Mordo who later went on to become Doctor Strange's arch-enemy. But when Nikolai's plans to recreate a new Carpathian Kingdown through sorcerous means came close to fruition, Krowler ordered Sara to kill her husband, which she did gleefully, catching him unaware and channeling her father's power.

    Sara then took her son, left Varf Mandra and returned to live at her father's castle, where young Karl Amadeus was tutored by Viscount Krowler. However, one day, the teenage boy overheard a conversation between his grandfather and his mother in which they revealed they had killed his father. Karl then and there swore to kill them both.

(Doctor Strange II#51/Doctor Strange: Sorcerer Supreme#7/2) - Krowler helped foster Hitler's rise to power by introducing him to a coterie of rich industrialists and dark mystics. He trained young Karl Amadeus into black magic and dispatched him to Tibet to learn and acquire more power from the Ancient One. During that time he secretly placed his Spell of Transference on the boy so that all magic that he would learn would become his as well. Thus it was through Karl and the Ancient One that Krowler learned of the existence of Dormammu and how to summon him.

(Doctor Strange II#50) - In 1943, Krowler entered into an alliance with Sir Anthony Baskerville. He secretly relocated to Castle Baskerville in Cornwall with a German squadron, and prepared to cause Dormammu to materialize on Earth. As part of his plan, Krowler secretly used the future Baron Mordo to bring Clea to 1943 and capture Doctor Strange.

(Doctor Strange II#51/Doctor Strange: Sorcerer Supreme I#23/2) - Krowler and Baskerville plotted to use the terror and hatred generated at the peak of the Blitz, and the sacrifice of Clea, to cause the materialization of Dormammu on Earth. Krowler asked Dormammu to release his grandson but the Dread One instead turned Future-Mordo into a ball of energy which he gave to Baskerville. Dormammu then took over Krowler's body. Baskerville later arranged for Future-Mordo to take over the body of Morgana Blessing, who had also traveled back to 1943, and was staying with Lady Pamela Hawley. But that attracted the attention of Pam's lover, Sergeant Nicholas Fury.

    Castle Baskerville was attacked by Sergeant Fury and the Howling Commandos. Eventually, the power of love which bound Strange to Clea, Morgana to Strange, and Fury to Pamela, was enough to countereffect the hate generated by the London Blitz. Morgana rejected Future-Mordo's hatred and simultaneously blasted Dormammu in the body of Krowler and enabled Doctor Strange (whose astral form had escaped Krowler's initial attack) to blast through Dormammu's snares and strike at Krowler too. Dormammu was banished; Krowler's mind was annihilated.

(Doctor Strange: Sorcerer Supreme I#7/2) - After Krowler returned to Germany, his mind and body broken after his battle with Doctor Strange, Sara cared for her invalid father. But Mordo, who was then living in Tibet with the Ancient One but has secretly been spying on them, saw an opportunity at last to fulfill his oath. Returning to Castle Krowler, he captured his mother and grandfather, and eventually sacrified both their lives to the Dread Dormammu, thereby sealing his alliance with the Dark Lord.

Comments: Created by Roger Stern, Marshall Rogers and Terry Austin.

    Krowler appeared in the Scholastic/Marvel graphic novel Captain America: The Ghost Army (2023). The story is set prior to Dum Dum Dugan joining the Howling Commandos, which would mean it would have to be set prior Doctor Strange II#50-51 - indeed, it also depicts the  formation of Krowler and Baskerville's alliance. Unfortunately the rest of the book's continuity doesn't match what we learned in Doctor Strange II#50-51; in that story, Krowler had sent Mordo to study under the Ancient One as a preteen but in the Ghost Army Mordo is already a  grown man and has yet to begin studying under the Ancient One. Further, we see how Baskerville loses his hand in the Ghost Army but he still had both hands in Doctor Strange II#50-51. The Ghost Army is unfortunately not set on Earth-616. - Prime Eternal
