Baron Karl Mordo is a magic-based supervillain and an enemy of Doctor Strange.
He was a former student of the Ancient One, until he betrayed his former master and killed him. He came into conflict with Doctor Strange , around this time.
Baron Mordo is enlisted by Doctor Octopus to bring the Green Goblin of Earth-1610 to his reality since he was unable to transform his Norman Osborn back into Green Goblin. Even though the plan worked, Green Goblin of Earth-1610 attacked both of them and claimed the Siege Perilous. With help from Spider-Man, Doctor Strange engaged Baron Mordo in battle. After Spider-Man got Miles Morales to his world to help fight Green Goblin of Earth-1610, Baron Mordo and Doctor Octopus worked to reclaim the Siege Perilous from Green Goblin of Earth-1610 whose punches started opening holes in the fabric of reality. Green Goblin of Earth-1610 punched Baron Mordo causing a hole to open on him enough to shatter him like glass as his remains fade away.
In reality, Baron Mordo is actually trapped in another dimension. he soon found a Quantum Realm resided on Ant-Man's lab, turning him into a Ant-Man and every civilian with an imaginary mind of Halloween into mindless monsters, then later used Doctor Strange, Spider-Man and Ant-Man to make Mordo escape to the real world, which is also powering him. He is soon defeated by the three heroes thanks to Spider-Man's advice to Strange and Ant-Man to use their imagination to counter Mordo's spell, sealing Mordo to another dimension once again.
