Miranda is a fictional shape-shifter from the W.I.T.C.H. TV series. Like Cedric, Miranda is a shape shifter with two forms, one human and one animal. In her human form Miranda is a beautiful, small Asian girl in her early teens, she wears a green and yellow dress and has black hair. In her animal form, she is a hairy four-legged, four-eyed spider-like creature with the power to climb walls and shoot webs. When knocked unconscious, Miranda returns to her human form. While masquerading as a student in Heatherfield, she went by the alias Melinda.

Miranda was voiced by Grey DeLisle. Her spider form's voice provided in the first season by Susan Silo and her human form was voiced in one episode by B. J. Ward.

Season 1
Miranda was first introduced into the animated series mid-way through Season 1 when she was brought in by Phobos to act as a friend and playmate for Elyon. In this guise she played the part of an orphaned servant girl who was taken in and cared for by Phobos after her parents were killed by monsters. Her primary role was to keep Elyon occupied, and to help Phobos maintain the illusion of being a kind and benevolent ruler, by concealing or explaining away anything that showed this not to be true. Her deception and true nature were revealed to Elyon late in season 1, when right after Phobos reveals his true intentions to Elyon, she begs Miranda for help, but she scorns her mistress and transforms into her beast form. Miranda was imprisoned along with Phobos and the rest of his minions at the end of season 1.

Season 2
Early in season 2, Miranda was released from confinement by Nerissa. She, along with several other former minions of Phobos, joined the Knights of Vengeance. Miranda, along with Sandpit, then traveled to Earth, where she masqueraded as a new girl, named Melinda, attending Sheffield, and attempted to implicate W.I.T.C.H. in Elyon's disappearance from Earth. Her efforts were thwarted when Elyon returned from Meridian.

After failing to frame W.I.T.C.H. on Earth, Miranda lead an attack on Elyon's prison, freeing Phobos, Cedric and the Lurdens who had remained loyal to them. However, her former master was less than grateful, due to the fact Miranda had not released him from his cell when Nerissa had freed her. As punishment, he shrunk her to the size and form of common spider, and abandoned her in a cell with Cedric.

When Nerissa threatened both Earth and Meridian, Caleb and the Guardians allowed Phobos to release Miranda and Cedric, on the condition that they help them to defeat Nerissa. When Phobos betrayed the Guardians, Miranda followed him, however she later double crossed her former master and joined with Lord Cedric during the invasion of Kandrakar. At which time was revealed that she and Cedric were romantically involved, and that they had been plotting against Phobos ever since he abandoned them in the castles dungeon at the beginning of the season.

Despite using the power of the Sceptre of Phobos (formerly the Seal of Nerissa), to grow to an enormous size, Miranda is eventually defeated by the combined efforts of Caleb, Blunk, and Sandpit and back in prison.
