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.

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.

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.

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

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