Human Form[3]

Dr. Thomas Lightner was a scientist who rebuilt his relative's Sky Cannon after his father Raymond disappeared during a mishap with the device. A similar mishap with the rebuilt device caused the energies from Raymond to merge with Thomas, giving Thomas the powers of a black hole. Taking on the name Blacksun, Thomas was opposed by the Thing, Human Torch, and the time displaced Doc Savage, who were summoned by Thomas' sister Janice in the present, and his relative Lucinda in 1936. Gaining increased power from the stars around him, Thomas' body could not contain these vast energies for long, and he collapsed and returned to his normal form.[3]


Lightner needed immediate medical attention, so the Thing and Torch took him to Doctor Donald Blake for medical attention. However, the Thing and Thor (Blake's alter-ego) were pulled into the realm of Celestial Heliopolis to battle the Egyptian death god Seth.[4] The pair were able to defeat their foe so that Thor could return to Earth and resume his guise of Donald Blake. Blake was able to perform the surgery needed to save Lightner's life,[5] restoring him to human form in the process.

Nth Man[6]

Lightner was later contacted by the Roxxon's Nth Command to infiltrate and sabotage Project PEGASUS.[7] Lightner hoped to use the project's Nth Projector to regain his previous powers. Lightner released Nuklo[8] and allowed Thundra and the Grapplers in to cause destruction and distract the facility's staff.[9] Lightner was supposed to use the Nth Projector to send the Project: Pegasus facility into another dimension, but instead used it on himself.[10] Lightner was transformed into the Nth Man, a "living interdimensional vortex." Like a black hole, the Nth Man absorbs all nearby matter and energy into himself. All of the heroes at the facility were absorbed into him, and Wundarr the Aquarian was able to use his null field to shut off the Nth Man's powers.[6]

Becoming Mysterium[11]

Instead of being destroyed, the Nth Man entered an alternate world, where he continued to expand until the entire universe was destroyed, at which point he passed into another world. In total, his expansion destroyed seven realities, until he passed into the Earth of Earth-712. There, he threatened to consume the sun, but the Squadron Supreme defeated him at a great cost and were banished to Earth-616 for a time. Lightner became Sorcerer Supreme of Earth-712 by switching places with Benjamin Jones who restored the damage Lightner caused.[11] When the Squadron Supreme returned to their reality and found their world fell under the totalitarian rule of the Global Directorate, Lightner, who called himself by his new identity as Mysterium, implored the Squadron to repair what had begun by their efforts in the Utopia Program and charging them with contacting other members of their team.[12]

Currently, he has magical powers, presumably on par with Doctor Strange.

As Blacksun, he could absorb all heat and light, and possessed a powerful gravity well, much like a black hole. He possessed great strength (@ Class 100) and durability. He could also bend matter and energy about his body to prevent them from striking him. Dr. Raymond Lightner's mind was dominant, although both were active.

As the Nth Man, he served as a living space warp, "a sentient singularity, drawing matter and energy into the nigh-infinite dimensions" of his own form. He could absorb all forms of matter and energy, growing larger and more powerful as he did so. There was no limit to this, and he would continue to enlarge until he absorbed an entire universe, at which point he would break through the dimensional barriers into another universe, and start the process all over again. He was vulnerable to nullifying his powers, such as via the null-field of the Aquarian. As he grew larger and more powerful, even this sort of attack, as well as attempts to shunt him into another dimension, would have limited effect.

  • Thomas Lightner's identity as the Mysterium is a possible pastiche of DC Comics's Phantom Stranger.
