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

Mandy is one of the two title characters from  and is voiced by Grey DeLisle. She along with Billy are the owners and best friends of the Grim Reaper.

During the first four seasons, she was a cynical, yet charming character. But during, a more malicious side of her personality is shown.

Why She Sucks Now

 * 1) Her attitude has gone from being passable to intolerable.
 * 2) Unlike her personality from the first four seasons, she is much more meaner and has done several evil acts than she once did. She was much more laidback and calm, 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 about Grim and Billy anymore.
 * 5) She usually betrays her friends.
 * 6) She also seems to do stuff that's just as dumb as Billy would do.
 * 7) 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.
 * 8) In the episode "The Greatest Love Story Ever Told Ever", it is revealed that she only agreed to go on a date with Nergal Junior just so she can watch him and Irwin fight over her and ruin Valentine's Day for everyone.
 * 9) She has hit rock bottom in the crossover special “” 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.
