Early Life

Baron Karl Mordo was born in Varf Mandra, Transylvania, Romania the son of Baron Nikolai Mordo and Baroness Sara Mordo. He gained an interest in magic and the occult from his grandfather; Viscount Heinrich Krowler.[2] He wished to expand his knowledge so travelled to the mountains of Tibet to find the fabled Ancient One.[3]


Karl Mordo (Earth-616)

Baron Mordo

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 when he began studying under the Ancient One and magically restrained him from speaking when Strange accidentally walked in on Mordo's plot.The plot failed, Strange became the Ancient One's disciple, and Mordo eventually left.[4]

Doctor Strange

Mordo continued his studies and became a fierce rival of Doctor Strange. They battled many times, in an early account Baron Mordo used his powers to try and eliminate the Ancient One. Baron Mordo controlled the Ancient One's assistant to poison the Ancient One. Sensing his master in trouble, Strange battled Mordo in his ectoplasmic form, preventing Mordo from ending the Ancient Once's life. [5] Strange was soon targeted by Mordo directly, who lured Strange to England to aid mystic Sir Clive Bentley. Strange only found Clive's daughter Victoria Bentley, a latent mystic herself, and fell into Mordo's trap. When the Baron attacked Strange, he was still no match for Stephen's superior mystical abilities and was forced to flee the scene. [6] Mordo soon struck again, this time tricking Strange into leaving his body in his spirit form. Knowing that if Strange was separated from his mortal body for more than 24 hours he would die, Mordo trapped his ectoplasmic form. Seeking the Ancient One's aid, Strange was able to recover a mystical ring that allowed him to break Mordo's spells and return to his mortal body, banishing Mordo once again.[4]

Mordo created a miniature replica of the Sanctum and plannedthat transport Strange and his home into an unknown dimension. Seeking the spell's source Dr. Strange travels in ethereal form to the home of Baron Mordo where he falls into another trap, a bottle like prison. Mordo arrives at the Ancient One's house only to discover that Strange has reached there before him. Mordo's magical prison had no floor. By descending downwards through the Earth Strange had eventually weakened the spell enough to break free. In the following magical battle Dr. Strange's good powers defeats Mordo's evil ones.[7] Mordo stole Strange's body when he was in the Astral Plane. He hoped his body would die with out it's soul . he sent an ectoplastmic warrior to attack him . He put his body on display in a wax museum. They battled in the Astral plane and Stange wins traps him there and places Mordo's body on display in the wax musem.[8] Mordo kidnapped the Ancient One. Strange searched the world over trying to find the Ancient One while simultaneously trying to prevent Mordo from capturing him. Finding and freeing the Ancient One in ancient Aztec ruins, Dr. Strange confronts Mordo and defeats him in a mystic duel.[9]


Dr Strange & Clea (by Mike Okamoto)

Dormammu also employed Mordo as a pawn to try and enter Earth. He sent Mordo and his minions to attack the Ancient One. Mordo then sent out a message to all evil mystics to help destroy Strange. He sent his minions to kill Strange in Hong Kong.[10] But he escaped them.[11] When Strange returned home, Dormammu infused Mordo with his mystical might and sends him to battle Strange allowing him to easily defeat him.[12] He sends him to the Dark Dimension.[13] Mordo was forced to fight Strange again when he return home. Clea helps Dr. Strange gain the upper hand by unleashing the Mindless Ones in order to keep Dormammu busy long enough for Strange to bind Mordo and his minions in molecules.[14] Mordo sent one his minions to do his bidding, channeling his mystical powers through him. Mordo's minion was easily defeated. Mordo arrived shortly after to find that his opponent has escaped.[15] Baron Mordo kidnapped the unconscious body of the Ancient One and transported him to the Dark Dimension and is now being held hostage along with Clea. Strange is then told to duel Mordo for their freedom.[16] Mordo loses the battle from the Dark Dimension. Fed up with Mordo's constant bungling, Dormammu transports Strange, Mordo and the Ancient One to the Dark Dimension.[17] During a battle with Dormammu, Strange was blasted in the back by Mordo.[18] Furious that Mordo would interfere in an honor battle against Dr. Strange, Dormammu banishes his minion but it was to late and Strange defeated the demon forcing him swear to not to invade his dimension.[19]

When Dormammu was defeated by Eternity, Doctor Strange was able to reverse all his spells returning Mordo[20]. But he trapped him back in a mystical prison.[21]

Mordo escaped from his prison teamed up with a group of mysitcs freed after the defeat of Zom .They formed a group known as the Circle Sinister Dr. Strange tracked down the Circle to their meeting place where he battle Mordo.[22] However Strange was able to convince Mordo to help collect all the evil mystical essence via a rite of Exorcism. In order to collect all the fragments together, they must be contained in a human host, a role which Mordo agrees to take. After the exorcism is complete and all the evil power unleashed by Zom is collected into Mordo's body, Mordo turns on Strange, striking him down.[23] Easily overpowering Dr. Strange with his new found power, Baron Mordo banishes the Doctor to another realm.[24]Strange returned with the Staff of Polar Power and battled Mordo, the staff absorbing Mordo's excess mystical powers and banishing him to another realm. [25]

Mordo took over the identity of Dr. Strange when the original was powerless. During a battle at the Sanctum. But Strange regained his powers from the Ancient One. Strange then attacked his imposter once more and easily defeats the foe. Unmasking him, Strange finds that his poser is none other than his mortal enemy Baron Mordo.[26]

Strange seeks the aid of the Aged Ghengis, but finds that he has gone completely insane due to Nightmare's machinations as well.As Mordo awakens from another nightmare.[32] Mordo himself reached out to the Aged Genghis in his astral form.[33] Mordo regained his mind and invaded the world which Eternity has sent Strange, attacking him with the very madness Mordo was infected with. Clea arrives to attempt to help Strange, however Mordo has engulfed the world with his madness causing it to destroy.[34] Mordo robbed the San Gabriel Archives at the Vatican. Strange learned Mordo was now free and learned Lord Phyffe was now working for Mordo who intended to cast a spell to open the Seven Gates of Chaos, which will ultimately destroy the Earth.itself.[35] Mordo offered Phyffe a new home in the new universe that Mordo intends to create once he succeeds.

Mordo returned and spied on his old enemy. He attacked him at Morgana Blessing's apartment. Mordo's powers have been boosted to near infinite levels by his time away from Earth. Mordo seemingly defeats Dr. Strange. He then turns his attentions to Morgana and is about to kill her when he is attacked by Morgana's cat. This cat is in reality possessed by the astral form of Dr. Strange who uses the moment of distraction to unleash the full force of his power casting a mighty spell that seemingly destroys Baron Mordo and restores everything to normal. Morgana approached her cat her cat the next day but was really Mordo in disguise. Mordo had survived the battle, killed her real cat and taken it's place so that he may sneak into Strange's Sanctum.

He traveled back to England in 1943. He ahd Mordo are taken prisoner by that era's Dormammu.[2] Viscount Heinrich Krowler used his grandson, Karl Mordo, with as a pawn to achieve great mystical power. Casting a spell on the young boy that would send all his mystical knowledge back into the past for his grandfather to utilize, he would use his mystical influence to help boost Adolf Hitler's bid to power become second to the Nazi leader himself. When the adult Mordo would traveled into the past, he had played into his grandfathers plan who overpowered him and would use his magical might to assist Dormammu, who hopes to gain access to Earth in it's past during a time when Doctor Strange was notaround to stop him.When Krowler asked Dormammu to spare his grandson, Dormammu refused and transformed Mordo into his most basic mystical form. Using Dormammu's past-incarnations own power against his present self, Strange casts a love spell through his body, connecting it to everyone in the room destroying the spell and seemingly destroying Mordo, and Dorammmu and driving Krowler mad in the process.[40]

However, after Spider-Man and Doctor Strange were involved in a time traveling adventure, it seemed that a younger, evil Mordo existed.[51]

The Offenders

Offenders (Earth-616)

Mordo and the Offenders

[52] 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".[53] 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.[54]

Baron Mordo's corpse was seen by Kang in Brazil,[59] where Thor's magical axe was being held, apparently killed by that weapon. [60]

Power Grid [61]
Energy Projection
Fighting Skills
* Teleporter


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 Field He can erect energy shields or screens with a high degree of invulerability 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,
  • Hypnotism: 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.


  • Expert Occultist/Expert Magical Knowledge: During his studies Mordo has become and expert awareness on cults and the extra dimensional entities they worship.[3]
  • Skilled Martial Artist: Mordo is a skilled athlete and was trained in the martial arts used by Tibetan monks in Kamar Taj.[3]


  • Human Factor: Another weakness is that Strange, despite all his spells and magical training, is only human physically. Hence, if not taking proper care or defenses, Mordo can be overpowered by mere blows, energy attacks, or gas. He still must eat, sleep and breathe in order to survive.[3]
  • Astro-Limits: Such is the skill and mastery of Mordo that he is capable of spending up to 24 hours upon the astral plane before he must rejoin his ethereal form with his physical one, lest succumb to corporeal deterioration leading to bodily death and eternal suspension as a spirit. The physical form remains in an inert, death-like trance, vulnerable to both physical and magical forms of harm while the astral form is absent. If harm were to befall his physical form while he was in his astral form, he would be stranded in his wraith-like state.[8]
