Eternia celebrates Teela as its new Man-At-Arms, but the knighting ceremony is cut short when Skeletor leads a full-scale attack on Grayskull.

Now mercenaries, Teela and her partner accept a job from a mysterious woman: to retrieve an old goblet from deep within Snake Mountain.

While defending a village from Tri-Klops's cult, Teela's group meets Man-At-Arms, who is struggling to keep Orko alive using the town's magic water.

Separated from her companions in Subternia, Teela faces a sinister entity who offers her half of the Sword of Power in exchange for her fears.

A familiar figure warns Teela and the others that there may be no escape from Preternia. Roboto risks his mechanical body to reforge the Sword of Power.

While the Sorceress, Adam and the others look on helplessly, Skeletor exploits his newfound power to evil lengths, plunging Eternia into chaos.

Adam calls down the power of Grayskull without wielding the sword and clashes with Skeletor, then sets his sights on an improbable target.

As Evil-Lyn begins to doubt Skeletor's motives, she recalls how she first met the power-mad tyrant and ultimately decides to make an unexpected move.

Aware of her legacy, Teela tries to manifest her powers to call for aid in their struggle against Evil-Lyn, while Adam partners with an unlikely ally.

Teela assumes her new role and Adam reclaims the Sword of Power as the final confrontation for the fate of Eternia — and the entire universe — begins.
