Millennia later, Kulan Gath returned to life in the modern world when the necklace that housed his essence turned up at a museum display in New York City.

The Avengers — consisting of the Wasp, Iron Man, She-Hulk, Warbird, Goliath, the Scarlet Witch and Triathlon — and accompanied by their ally Silverclaw, traveled to Costa Verde to stop him.

In the 2008 Spider-Man/Red Sonja mini-series, Gath was able to return to Earth when the amulet came into contact with a corrupt US senator, providing him with a new body that he subsequently used to transform New York City once again.

Gath went on to kill many other super-heroes and reverted the entire world back to a primitive age which he ruled over, turning the population into a barbarian army under his control.

Fantastic, symbolizing his final triumph over the modern age of science and super-human heroes, when alternate universe versions of X-51 and Hyperion arrived hoping to warn the people of that reality of the Celestial seed in the Earth's core.

When Gath stated that the Celestial seed was the source of his power, Hyperion killed him, allowing X-51 to pass on information to the people of that reality to help them save their world.

[13] Screen Rant reviewer Bryce Morris characterized Kulan Gath as a famed villain from the Conan the Barbarian series, as well as "one of the most powerful" and the "darkest sorcerer" in the world of Marvel Comics.

[3] Morris' colleague Thomas Bacon labelled the character "the darkest Sorcerer Supreme" from the Marvel Comics, "a classic villain" and "a formidable foe" to other powerful players in their fictional universe.

[5] Comic book author Amy Chu stated in KISS in 2017 that in her view "Kulan Gath has been pretty much treated as a very one dimensional villain", focussing on his trait of megalomania.

[14] James Lowder commented critically about the use of the character in Uncanny X-Men #190–191: "As a spectacle, the Kulan Gath story worked well enough", with the evil wizard causing "blood-letting sadistic enough to sate fans of Grand Guignol-style entertainment".

But Kulan Gath's strikingly depicted torture and murder of Spider-Man and other characters in which readers were deeply invested, combined with the "cheat ending", where the sorcerer was defeated and all events erased by resetting the timeline, produced in Lowder's view a "profoundly unrewarding" tale.
