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

William "Billy" is one of the two title characters from The Grim Adventures of Billy & Mandy. He is voiced by Richard Steven Horvitz. He and Mandy are the owners and best friends of the Grim Reaper.

During the first four seasons, he was a simple-minded, yet charming character. But during the last two seasons, a more malicious side of his personality is shown.

Why He Should Be Destroyed Now
Note: This only applies to his character as depicted in seasons 5-6 of The Grim Adventures of Billy & Mandy and the crossover special The Grim Adventures of the KND, as he was flanderized.
 * 1) Much like Patrick Star (seasons 6-8), Stimpy (Adult Party Cartoon) and Sheen Estevez (Planet Sheen), his stupidity has gone from being hilarious, funny and charming to irritating, unfunny, and stale.
 * 2) Similar to SpongeBob SquarePants (seasons 6-7), he used to be much more cheerful and carefree, but now has become a much bigger nuisance towards everyone, mostly General Skarr.
 * 3) He and Mandy have become huge bullies towards Grim.
 * 4) He now refuses to follow Grim and Mandy's orders and does what he wants.
 * 5) His voice, while still good for the most part, can be grating to listen to at times, particularly when he yells or screams.
 * 6) He provides much more gross-out humor than he already did in the first four seasons. For instance, in one episode it is revealed that he poops in General Skarr's garden and eats his flowers.
 * 7) He was at his worst in the episode "Everything Breaks", where he says that he smashes stuff just because he thinks it's fun.
 * 8) He is also just as mean as Mandy is, which is evident when:
 * 9) * In the episode "The Love That Dare Not Speak Its Name", he repeatedly assaults Grim just because Blandy had a crush on the latter instead of him.
 * 10) * In the episode "Be A-Fred, Be Very A-Fred", he blames Grim for making Fred Fredburger cry when it was actually his own fault along with Mandy.
 * 11) * He was much meaner to Jeff in the second film Mh:greatestmovies:Billy & Mandy: Wrath of the Spider Queen, where he refuses to have Jeff marry Velma and calls her ugly.
 * 12) He is responsible for literally everything that occurred in the crossover special "The Grim Adventures of the KND". The only difference is that Mandy was just speeding things up.
 * 13) He barely gets punished for his actions, making him a karma houdini (and an idiot houdini, due to his idiotic behavior).

Redeeming Qualities

 * 1) He was a much better and more tolerable character in the first four seasons.
 * 2) He still has his hilarious moments whenever he is in character.
 * 3) There were still a few moments where he cares about Grim and Mandy.
 * 4) Richard Steven Horvitz still did a good job voicing him, except when he yells or screams, as said earlier.
 * 5) He did get his comeuppance in "Detention X" where he was sent to a dimension full of things that he was scared of/didn't like.
