|First appearance:||Ginger the Juvey|
|Voiced by:||Cree Summer|
Miranda Killgallen is Courtney Gripling's best friend, and her sheer meanness will make sure that no one else takes that position (voiced by Cree Summer).
Miranda's icy cruelty can be traced back to a strict upbringing from her overbearing father. She is fiercely loyal to Courtney and becomes jealous if Courtney pays attention to any one else. She is the meanest to Ginger Foutley, especially after Courtney begins acting friendly towards her. Miranda tries her best to humiliate Ginger any chance she gets, cackling with laughter at every one of Ginger's failures. Miranda's dislike for Ginger mainly stems from her fear that 'Foutley', as she calls Ginger, may replace her as Courtney's best friend, in addition to being jealous when Courtney gives her attention to anyone but her. Miranda's dislike for Courtney's associates goes beyond Ginger, however. In "Sleep on It" Miranda also expresses her contempt for Courney's arriving guests. Adding fuel to fire is Ian Richton, a boy that is in their chemistry class who both girls have a crush on. Ginger's romantic interest sizzled; however, when she realizes Ian was only using her to get an "A" in the class ("The A ticket"). Miranda has thwarted Ginger by all means possible, including manipulation (Dare I, Darren), blackmail (Cry Wolf), false accusations (I Spy A Witch, Ginger The Juvey), backstabbing (Wicked Game) and bribery (Far From Home).
Nevertheless, a small part of her is still kind and she has has been known to do something nice - though she goes to great lengths to hide it. Even 'tough girl' Miranda has a weak side: she has a difficult relationship with her strict parents and has very few actual friends. She uses being mean as a cover up and takes out her frustration on her classmates, especially Ginger.
She's left friendless when she and Courtney have a temporary falling out; Macie states that it's because no body likes her (Trouble In Gal-Pal Land).
Apart from her viciousness, Miranda's trademark is her sniping, sarcastic comments.
Courtney Gripling: Miranda and Courtney are best friends. The two are almost always seen together and Miranda cares a lot about Courtney, even crying when she knew that Courtney wasn't enjoying her stay at Camp Caprice. She is jealous and mean to Ginger because Miranda feels like she is trying to take Courtney away. She goes to to extreme lengths to get Ginger and Courtney to stop being friends.
Mipsy Mipson: Miranda and Mipsy are good friends, though not as close as Miranda is to Courtney. They do share the same hatred for Ginger and often work together to sabotage Ginger's life and friendship with Courtney.
Ginger Foutley: Miranda's worst enemy - at least she believes this to be true. Miranda hates Ginger and often goes out of her way to be mean to Ginger, from making fun of her clothes to getting her arrested. When she finds out about Ginger's "frizzy lizzies" (her unshaven legs), she blackmails Ginger into not hanging out or even talking to Courtney "Cry Wolf".
- Her appearance in the pilot was radically changed to her known appearance in the series.
- At the end of the series, Miranda and Courtney are not seen at Ginger's book reading, though a woman who appears identical to Miranda is seen walking past the library.
- Miranda's ethnicity is half African American and half Egyptian American.
- Cree Summer, Miranda's voice actress, also voices Numbuh 5 (real name: Abigail Lincoln) from Codename: Kids Next Door as well as Numbuh 5's evil older sister, Cree. Voice-wise, Miranda sounds more like Numbuh 5, but personality-wise, Miranda's more like Cree.
