Baron Karl Mordo gained an interest in magic and the occult from his grandfather.

Mordo began his tutelage under the Ancient One as early as the 1930's, already an adult; residing in the Ancient One's lair brought him reduced aging. The Ancient One realized that Mordo's lust for power made him dangerous but chose to teach him anyway feeling that he could at least keep a watchful eye on him.

Mordo was immediately resentful of Stephen Strange and magically restrained him from speaking when Strange accidentally walked in on Mordo's plot[1]. The plot failed, Strange became the Ancient One's disciple, and Mordo eventually left.

Mordo continued his studies and became a fierce rival of Doctor Strange. They battled many times[2][3][4][5][6]. Dormammu also employed Mordo as a pawn to try and enter Earth.

At some point, Mordo had an encounter with Dracula, saving a woman from him only to use the woman as a sacrifice. Considering Mordo's ancestral castle is also in Transylvania, this is not all that surprising.

It is not clear whether Astrid was born before or after Mordo's magical studies, but he apparently instructed her in magic. When he later became ill, she attacked Doctor Strange. Baron Mordo discovered he had cancer. Attempts to heal this failed, and he returned to Tibet to seek forgiveness from everyone, including Strange. He was forgiven, and died at peace.

However, after Spider-Man and Doctor Strange were involved in a time traveling adventure, it seemed that a younger, evil Mordo existed.

Additional History by Unofficial Handbook Website

Karl Amadeus Mordo always had some affinity for magic, his father was a powerful black magician and so was his grandfather. When his grandfather the Viscount Crowler and his mother killed the father of Karl they took him to castle Crowler her he received tutoring in the mystic arts by the Viscount himself.

When he learned all there was to learn from the Viscount he went on a quest in search for the Ancient One, he who was known to be very powerful. And it was power Mordo was searching for. Power to revenge his father.

Determined to find this master of the mystic arts, Mordo made his way through the frozen wastes of the Himalayan Mountains. When he finally reached the palace, he only was accepted as the Ancient One's disciple because the latter felt in Mordo the ability for evil and decided that this was the best way to keep Mordo in check.

While Mordo was plotting against the Ancient One, during a session in which Mordo had contact with Dormammu, he was discovered by Stephen Strange who, at that time, was the guest of the Ancient One's. Trying to warn the master of his pupil's treachery, Strange was discovered by Mordo and mystically restrained. But because of the fact that the Ancient One knew of the nature of Mordo, this act merely resulted in Strange becoming the Ancient One's new disciple.

Leaving the Himalayan palace, Mordo ended getting his revenge when he sacrificed Viscount Heinrich Crowler and his mother baroness Sara Crowler-Mordo. With this act Mordo burned all his former feelings except those he had for his father and his hatred against the Ancient One and his new found pupil. Mordo remained a bitter foe of Strange, now Sorcerer Supreme of the Earth dimension. As such, the two have clashed repeatedly over the years. At one point, Mordo served the extra dimensional entity known as Dormammu, seeking to amass more power for himself, although Dormammu was defeated by Strange.

Then came the day that all the dark magic he used over the years to keep himself young finally betrayed Mordo by giving him terminal cancer. This changed him dramatically. Feeling his end come near, he sought forgiveness for his deeds from Strange. But Mordo's daughter Astrid, who followed her dad's old footsteps, transferred the cancer into Strange's body. Only after Mordo redeemed himself by defeating and banishing his own daughter followed by taking the cancer back, did Strange found it possible to forgive him. That's when the cancer sapped the last breath out of Mordo. He died knowing that his old enemy could forgive him.

The Offenders

Mordo and the Offenders
ADourAdded by ADour

Baron Mordo was picked at some point in the past by the Collector, among others, when he settled a bet with the Grandmaster.

The Collector teamed up Red Hulk with Tiger Shark, Baron Mordo, and Terrax against Hulk, Namor, Doctor Strange, and Silver Surfer. Eager for revenge on his counterpart, Red Hulk agreed to take part in the fight, dubbing his team "The Offenders".

Mordo confronted Strange and Dormammy but was killed by Rulk as all the participants. They were all resurrected and sent back to their time-lines with no memories.[7]

X-Factor and death

Later, Mordo located to South America. He helped by an army of followers, kidnapped Monet St. Croix's father, Cartier, in order to made her coming and giving her energy to cure his cancer. Confronted to M and her teammate of X-Factor Guido Carosella and targeted by the M.R.D.'s bombers, he agree to teleport the heroes and Cartier to X-Factor's hideout, in exchange to Monet's energy once the teleportation done. M tricked him into believe he killed X-Factor and was cured, and let him go, half crazy.

Baron Mordo's corpse was seen by Kang in Brazil, where Thor's magical axe was being held, apparently killed by that weapon.[8]

Powers and AbilitiesEdit


Baron Mordo had the ability to tap this universe's infinite store of ambient magical energy and manipulate this to a variety of effects. The skill derived from three major sources: personal powers of the mind/soul/body, powers gained by tapping the universe's ambient magical energy and employing it for specific effects, and, finally, powers gained through the tapping of extra-dimensional energy by invoking entities or objects of power existing in tangential mystical dimensions. (The latter means of power is usually gained by reciting incantations.) Some of these effects included:

  • Magic Energy Blasts: Forming magical energy bolts with a high degree of potency and control
  • Force Fields He can erect energy shields or screens with a high degree of imperviousness to both physical and magical damage.
  • Astral Projection: The art of astral projection, the mental ability to separate the astral self-the sheath of the soul, or life essence-from his physical self, and in this form traverse through space unbounded by physical laws but fully retaining human consciousness. The astral form is invisible, intangible, and incapable of being harmed except by the most rigorous of mystical means. The astral form only possesses those magical powers residing in the sorcerer's mind: thought casting, psychokinesis, etc. He has such mastery that he can remain in astral form for up to 24 hours and even more before there is corporeal deterioration of his physical form. The physical form is quite vulnerable to attack when the astral form is absent. If harm were to befall the physical form while in astral form, the astral form would be stranded in the wraith-like state. While the astral form is absent, the physical form remains in an inert death-like trance.
  • Thought-Casting: He is capable of Thought-casting over short or vast distances in a manner virtually identical with telepathy. The entire Earth was within the reach of the Ancient One's mind, providing he knew where to contact the specific mind he is seeking. He could simultaneously communicate with more than a dozen minds at a time.
  • Teleportation: Utilizing local magical energy to teleport across the face of the Earth or into a mystical dimension (certain higher dimensions beyond height, width, depth, etc. where the physical laws can be based on magic rather than science). Oddly enough, teleportation within a dimension is more taxing than teleportation between dimensions. Such expenditure of energy leaves all sorcerers mystically debilitated for a varying length of time, making teleportation a dangerous and seldom used ability. Physical teleportation across time rather than space is the most power-draining feat of them all.

Aside of the above mentioned manipulations he had been known to use spells capable of:

  • Opening dimensional gateways
  • Levitating
  • Illusions: he can create life-like illusions,
  • Hypnotisym: he can mesmerize others
  • Materialization: he can summon objects, elements, and beings.
  • Necromancy: Mordo also dabbled in necromancy-- magic of the dead. He once used the spell book of Cagliostro but since lost it, and later possessed occult books of his father's and those that were owned by Viscount Crowler.
