Calling itself only Strange, the being first assisted the Midnight Sons against Zarathos and the Fallen.
"Strange" then began searching the world for artifacts of Earthly magic and brought them back to Dr. Stephen Strange. This led to conflict with the items' guardians and other individuals looking to claim them, including Nathaniel Richards and Namor.
After a second confrontation with Salome, Strange sought to combine with Stevens to merge their power. Failing this, Strange looked for alternate sources of power, targeting Lorna Dane, Rick Jones, and the Infinity Gems.
Strange was temporarily abducted by the technologically advanced Clave, who believed that he was the ancestor of their hated rivals, the magical Kynd.
Dr. Stephen Strange, having newly mastered the Gaian Aura, finally confronted his "Strangers."
In response to Clea's request for aid, Strange made a compromise to continue existence: he merged with Nobel the Progenitor (a dying member of Clea's group) and was given the name Paradox.
On a subsequent return to Earth, Clea returned what appeared to be Paradox's cloak; it is presumed that Paradox was destroyed battling Dormammu's forces.
