During the "AXIS" storyline, a fragment of Professor X's psyche (which had escaped the scrubbing of his memories) still existed in Red Skull's mind preventing him from unleashing the full potential of Professor X's powers. During a fight with the Stark Sentinels, Doctor Strange and Scarlet Witch attempt to cast a spell to invert the axis of Red Skull's brain and bring out the fragment of Professor X to defeat Onslaught. Doctor Strange was targeted and captured by the Sentinels before they could cast the spell. When Magneto arrived with his supervillain allies, Doctor Doom and Scarlet Witch attempted to cast the inversion spell again and Red Onslaught was knocked unconscious and reverted to his Red Skull form. Although they did not know whether Professor X was now in control, the Avengers decided to be cautious and take Red Skull to Stark Tower. It was later revealed that the spell had actually caused all the heroes and villains present to undergo a "moral inversion" rather than simply bringing out Professor X in the Skull, with the result that the Skull and other villains became heroic while the Avengers and X-Men present became villainous. Eventually, the inversion was undone.
