Originating from 8th century, Abdul Alhazred is the creator of legendary Necronomicon, a powerful black magic tome patterned after the Darkhold. At some point Alhazred's spirit became trapped in the realm Pellucidar, a pocket dimension formerly accessed within subterranean Earth It has been hypothesized that Alhazred died in Pellucidar or that his spirit was transported there by the Great Race of Yith. Alhazred's spirit was stored within the crystal of Pellucidar's reptilian Mahar race.
Around 1920, a lieutenant in a minor band of slavers was caught stealing from his captain and hid in a cave, where he found a portal to Pellucidar. Energies released from the Mahar crystal allowed Alhazred's mind to control the thief, trasforming him into a more powerful version of Alhazred's own body before the portal closed. Alhazred took command of a band of slavers and forced them to unearth the portal to Pellucidar. One of the slaves fled from the caverns but was pursued and slain by Alhazred's slavers. This murder was seen and avenged by Tarzan who then pursued Alhazred into Pellucidar. The slavers had also captured and African princess, Ayesha, to serve as a sacrifice to the crystal in hopes of Alhazred regaining his full power. Tarzan and Ayesha separated from Alhazred who took command of a cannibal tribe and used their ship to speed his journey, ultimately arriving at the jungle Mahar city. Meanwhile, the Mahar had built a sonic weapon using the crystal, preparing to taking over Pellucidar. Locating the Mahar city, Ayesha found the weapon's controls, turning it against Alhazred and his allies and slaying Alhazred's pet hawk. The Mahar attacked Ayesha in their control room, and she was forced to vlow up the control device to save herself. Alhazred recovered and revealed his intent to sacrifice his allies to the crystal to gain more energy. However, Tarzan the arrived, following a stampede of dinosaurs and other creatures driven to frenzy by the sonic weapon. Alhazred attacked Tarzan, planning to sacrifice him instead, but the crystal began feeding off his own energies as well, and he was now vulnerable to other assaults. Alhazred was driven into the crystal, which drained all of his power and life energy, causing him to crumble into ashes.
In recent years Abdul Alhazred - or possible another host - sought to takeover the Madripoor crime empire of Tyger Tiger, intending to depose prince Baran and establish Madripoor as his power base and then to barter with other countries for the extradition of criminals who had fled there. Alhazred's agents kidnapped Tyger Tiger and Archie Corrigan, but internal conflicts caused them to crash their plane in Madripoor's jungles. From there, they were overpowered by Wolverine and sent to jail. Wolverine revealed the he was atleast familiar with Alhazredand respected, if not feared, his power and wrath.
Sometime later, Alhazred himself attacked and overpowered Wolverine, and then re-kidnapped Tyger Tiger and Corrigan. When Wolverine returned to free his allies, Alhazred unleased his demons, hoping to send Wolverine into a berserker fury, which Alhazred could then control. When Wolverine resisted, maintained mental control of himself, the psychic backlash caused Alhazred to be banished to the extradimensional demon realm.
