Mad Madam Mim

Mad Madam Mim is a famous witch known for playing mind games. She is a frequent participant in the villain wars, sometimes working alongside other minor sorcerers in the Sorcerer's Society.

She is the primary antagonist in the Disney animated film The Sword in the Stone.

Beginnings
Long before Jafar or the Sultan he served were even born, a different Sultan ruled over Agrabah, father to ten princesses. When bored or in need of a laugh, the Sultan called in his court magician--Ayam Aghoul, to use his elementary skills in sorcery to entertain him. Unknwn to the Sultan, however, Aghoul was quite the lecher, and more often than not, would spend the night with any one of the Sultan's daughters.

When the Sultan found out, Aghoul became a wanted criminal. After a nightlong chase with the Agrabah guard, Aghoul was captured, and ultimately executed (much to the sorrow of all ten princesses), his soul descending to the River Styx.

Fearing his fate and not at all ready to die, Aghoul devised an escape plan. It was his lucky day--his only obstacle was some tentacle guy wielding a scythe he clearly had no idea had to use.

Meanwhile, in Camelot, a travelling circus found a baby abandoned in the woods. The circus folk named her Mim and raised her as one of their own. By age three, they found that whoever her parents were, they were apparently wizards, as she showed a great aptitude for shapeshifting.

When Mim was only ten, she was brought into the show as the marvelous, transforming spectacle. Soon, Mim was the main attraction. Albeit, she never took her true form on stage. She'd become a myriad of animals and creatures but nobody outside the circus tent truly knew what she looked like.

One night drew in a bigger crowd than ever--and Mim, having lost focus for just a second, reverted to her true form. Stunted height, and frankly, very ugly, she was met with jeers and ridiculing laughter by the crowd.

Mim, confused and upset, took on the form of a dragon and went on a rampage. Citizens ran in fear as the circus burned to the ground. The king's knights, lead by Sir Ruber, captured the dragon and banished the witch to the wilderness.

In the forest, Mim kept herself occupied talking to the voices in her head and challenging anyone ill fated enough to cross her cottage to a Wizard's Duel.

Nobody that faced her could match her skill, that is, until the newly revived Ayam Aghoul happened upon her cottage. His time in the Underworld boosted his magic significantly. The two were evenly matched...and Mim liked that. A lot.

The two agreed to put their magic skills together as a criminal duo. The 'Magic Bonnie and Clyde' was very famous, and didn't go unnoticed by Mozenwrath...

During the war, Messina challenges Mim to a wizard's duel. Mim turns into a dragon, but Messina bites her, infecting her with a rare disease. Mad Madam Mim spends the remainder of the war in bed.

Back in Action
Yzma cures Madam Mim of her illness in order to form the Sorcerer's Society, all on the orders of Shan Yu. Mim is immediately put to the test when Mojo Jojo sends a monkey army to attack China. Mim proves a highly efficient combatant, transforming into a rhino in order to kill a gorilla enhanced with lethal sonic gloves. In the end, the Sorcerer's Society wins the battle.

The Battles of China
Mad Madam Mim helps Yzma and her allies defend China from the forces of Fire Lord Ozai. During the opening skirmishes, she takes down several minions with her magic as they attempt to scale the walls. She is also one of the sorcerers to attack Ozai himself. She uses her magic to grow to gargantuan size, but Ozai buries her in rubble. Nonetheless, she survives, witnessing Shan Yu's murder of the Fire Lord. In the second Battle of China, Madam Mim takes on Skull Sorceress; the fight is short, as Mim transforms into a dragon and easily incinerates her rival. She later celebrates when Shan Yu is crowned king of the world.

Griffon Slayer
The insidious Merlock invades Mim's cottage, disguised as a rat. Mim takes advantage of the situation, turns into a cat, and nearly devours her foe. Merlock transforms back into a wizard, only for Mim to shoo him away. Enraged, Merlock turns into a griffon, but Mim turns into a dragon. While Merlock is in flight, Mim knocks away the amulet that turns him into the griffon. Now without the power of flight, Merlock falls to his death.

Defeated from Afar
However, Merlock is the apprentice of Jafar. The sorcerer calls upon a favor from Maleficent: infecting Mim with a powerful diseased. Maleficent obliges, taking Mim out of the war due to severe illness.
