Maleficent's Staff is a magical golden scepter owned and wielded by the evil fairy Maleficent. It possesses great magical power that she uses for her evil purposes.
Sleeping Beauty: A length of twisted birchwood encased in gold and surmounted by an engraved lotus bearing a glowing crystal orb.
Once Upon a Time: A length of twisted willow surmounted by a blackened iron dragon, between whose wings rests either a red crystal orb, one filled with swirling mists or no orb at all.
Maleficent: A length of a twisted birchwood tree branch and a oval crystal ball on top.
Descendants: A long wooden powerless staff on the Isle of the Lost, with a green-like stone on the top. But when the barrier around the island was lifted the stone glows green and sparks as its owner was able to use its magic again.
Maleficent appears with her staff and her pet raven, Diablo, during Aurora's christening when she interrupts the celebration. She uses it to perform her evil magic as she put a curse on Aurora, saying that before the sun sets on her sixteenth birthday, she would prick her finger on the spindle of a spinning wheel and die (though Merryweather softened the curse so instead of dying she would fall into a deep sleep that will only last until True Love's Kiss). When King Stefan and his wife, Queen Leah orders their guards to arrest her, she uses her power and that of the staff to flee with Diablo. It is later used to punish her goons back at her castle in the Forbidden Mountain for failing to find Aurora. (They had been searching in cradles for sixteen years.)
On the eve of Aurora's 16th birthday and back at her parents' castle, the staff is used to transform Maleficent into a will-o'-the-wisp, hypnotizing Aurora before luring her to a remote tower, where Maleficent transforms into the spinning wheel on which Aurora pricks her finger to fulfill the curse.
After Diablo is turned into stone by Merryweather during their escape from Maleficent's castle, she uses the staff to summon lightning bolts and spells aimed at Prince Phillip in order to hinder him, including a "forest of thorns". Prince Phillip is able to overcome the mystical thorns, so Maleficent takes her staff and leaves her castle to personally deal with him by transporting herself in front of King Stephan’s' castle, blocking his entry. She then tells him that he shall have to fight her, and "all the powers of Hell" and transforms into a huge dark dragon. Though she overwhelms Phillip, and it looks like he is about to meet his death, the Three Good Fairies transfer some of their power to his sword and so he throws the enchanted weapon into her heart, fatally wounding her. As she falls forward, she attempts to devour him, but misses, and her heavy weight causes the cliff beneath her to crumble, and she falls to her death. The staff is nowhere to be seen, and all that's left is her shredded robe, with the sword still stuck in it, which blackens.
After Maleficent had her wings cut off by King Stefan, their absence made it difficult to balance. She creates the staff from a simple twig to help her walk, and later carries it to signify her position. Even when she regains her wings, she still wields it.
In the television series Once Upon a Time, Maleficent (portrayed by Kristin Bauer van Straten of True Blood fame) possesses a staff in which she hides the darkest, most vile curse imaginable, the Dark Curse. The Evil Queen, Regina, and Maleficent duel for the curse. When fire is shot at her, Maleficent uses her staff to create a shield to block her attack. Regina eventually bests Maleficent and takes her staff, only to smash the crystal orb on the floor, revealing the scroll upon which the spell is written. Maleficent warns her, however, that "all power comes with a price".
Maleficent's most shown use of it was when she was trapped within Bald Mountain. She pointed her staff at the Chernabog, though this only had limited damage on the demon.
The staff is shown to possess great power and can be used as extension of the powers she already has, as seen when Maleficent was able to use it to put the whole town of Storybrooke to sleep (though this was only temporary). She can also use the staff to shoot out purple powered beams and fire too.
The Staff also made an appearance in House of Mouse. It is used to punish the goons and to bop Hades and Captain Hook on their heads. It zaps Jafar during their date after he tells her that he's been searching for a Diamond in the Rough. In the film Mickey's House of Villains, during the song "It's Our House Now!", when the villains take over the House of Mouse, she uses it to transform into a fire-breathing dragon, impressing Chernabog.
The staff is present in the movie Descendants. Maleficent uses it to turn into a dragon. Mal gets a chance to hold it for a fort second. There is also a replica of the staff in the hands of a manikin of Maleficent in Auradon museum.
In Return to the Isle of the Lost, Mal notes that the staff broke when her mother turned into a lizard. The remains were stored in the museum, while the replacement Dragon's Eye was destroyed.
Despite the character of Maleficent being based on the animated counterpart from Sleeping Beauty and not the character of the 2014 movie, in Descendants, the staff is closer in design to the one seen in the live-action film.
