Mandy (The Grim Adventures of Billy & Mandy, seasons 5 and 6)

Mandy is one of the two title characters from . She along with Billy are the owners and best friends of the Grim Reaper. Unlike Billy's dimwitted and happy-go-lucky personality, Mandy has a sinister and gothic yet calmer and laid-back personality. She almost never smiles, and is voiced by Grey DeLisle. Despite being one of the “protagonists”, unfortunately, she was flanderized when seasons 5-6 came out. Even in the crossover special with Codename: Kids Next Door titled , she was kept flanderized as is, thus, officially ruining her entire character as a whole.

Why She Sucks

 * 1) Her demeanor has gone from tolerable to intolerable.
 * 2) Unlike her personality from seasons 1-4, she is much more meaner and has done several evil acts than she once did. She was much more laidback and calm in seasons 1-4, but here, her temper is much shorter and she beats up Grim, Billy, and Irwin just for fun.
 * 3) She along with Billy are huge bullies towards Grim.
 * 4) She doesn’t seem to care that much about Grim and Billy anymore.
 * 5) She usually betrays her friends.
 * 6) In "The Greatest Love Story Ever Told Ever", it is revealed that Mandy went on a date with Nergal Junior just so she can watch Irwin and Nergal Junior fight and ruin Valentines Day for everyone.
 * 7) She also seems to do stuff that's just as dumb as Billy would do.
 * 8) She was at her worst in the episode "Scary Poppins" where she brainwashes everyone in Endsville (except Grim) to follow her orders instead of becoming a much better person.
 * 9) Her most evil, villainous role is in The Grim Adventures of the KND, where she confronts and holds Numbuh 1 hostage just so she can rule the entire KND organization for world domination.
 * 10) She along with Billy barely get punished for their actions.

Redeeming Qualities

 * 1) She was much better and more tolerable in seasons 1-4.
 * 2) There were still a few moments where she cares about Grim and Billy, especially in Billy & Mandy's Big Boogey Adventure where she showed sympathy towards Billy when she thought that the sea monster ate him.
 * 3) Grey DeLisle did a good job voicing her.
