Weirdworld was a fantasy series created by Doug Moench and Mike Ploog for American company Marvel Comics, set in a dimension of magic.

Originally intended to be published in the discontinued Monsters Unleashed, the first "Weirdworld" story eventually appeared in the one and only issue of the black-and-white magazine Marvel Super Action.

[6] Moench's script was eventually published as a 106-page story illustrated by penciler John Buscema, inker Rudy Nebres, and airbrush colorist Peter Ledger as the three-part "Warriors of the Shadow Realm" in Marvel Super Special #11–13 (Spring–Fall 1979).

[10][11][12][13] Ploog's unused 1978 pages were reworked into the first part of a "Weirdworld" trilogy, in Marvel Fanfare #24 (January 1986),[14] with Pat Broderick penciling the two subsequent issues.

[15][16] The protagonists were the Elves Tyndall[17] and Velanna,[18] both from the floating ring-shaped island of Klarn, and an irascible Dwarf dubbed Mud-Butt because he tended to land on his backside in a quarrel.

Alone in Weirdworld, Rebecca agreed to become Goleta's squire and the two set off together, unknowingly being tracked by the Catbeast that had emerged from Ogeode's corpse.

Ogeode's Catbeast form then explains to get Rebecca back to Earth, they need to travel across the Fang Mountains to retrieve a spare wizard body.

[22] Rebecca met Eta the Watcher who urged her not to go to the Fang Mountains or else it would bring a full scale war to all of Weirdworld.

[25] Upon arriving on Weirdworld, he killed King Zaltin Tar to establish New Avalon and built an army with the help of Shield and Spear.

[26] Spider-Man and Deadpool hid from Itsy Bitsy in Weirdworld, where they helped the Bogswaggers escape from the Witch Queen le Fay and reclaim their land of Bathsalthia from the Kingslayers, as well as fighting the creature Sl'Ur'Boroth, whose arrival was heralded by the local Moloids.

When Weapon H, Blake, Man-Thing, Titania, Korg, and a disguised Black Widow travel to Weirdworld on Dario Agger's behalf, he finds that Roxxon had managed to capture Morgan le Fay in order to harness her power source.

Two of the Strange's students, the Asgardian twin sons of Enchantress Iric and Alvi were sent home but there mother's past would come back to haunt them.

Goleta, unable to pierce Pulsari's skin, managed to destroy the wizard's necklace, stripping him of his power and returning Iric to normal, in the process.
