The Sword of Protection is the weapon wielded by Adora, Prince Adam's twin sister, which she uses to transform into the heroic She-Ra.
Differences
Instead of Prince Adam's war-cry, "By the power of Grayskull," Adora's transformation is triggered by calling, "For the honor of Grayskull." Although its overall design is similar to the Sword of Power, the Sword of Protection is more slender, with a finer blade reflecting its female owner, and it has a jewel embedded in the hilt. The jewel is the key to such powers of the Sword of Protection as Adora's transformation; if it is damaged, she loses her ability to transform into She-Ra, as seen in the episode "The Stone in the Sword."
Powers
In addition to being as formidable as the Sword of Power and capable of cutting through most substances or deflecting attacks, the Sword of Protection has the ability to change its shape, a trait the Sword of Power does not share. She-Ra can transform the Sword of Protection into a variety of weapons or tools through spoken command, ranging from a shield or lasso, to a helmet or flaming blade.
