Bendy (Foster's Home for Imaginary Friends)

Bendy is a one-time character from mh:besttvshows:Foster's Home for Imaginary Friends, who appears in the infamous episode, "Everyone Knows It's Bendy" as the titular main antagonist. He is the imaginary friend of a boy named Gregory who was sent to Foster's because of his troublemaking.

Why Everyone Knows He Sucks

 * 1) For obvious starters, he caused trouble all over Foster's. He is characterized as a troublemaker who wants to put everybody through hell and always succeeds at doing so.
 * 2) His characterization is really flat and one-dimensional. He gets Bloo, Coco, Wilt, and Eduardo in trouble for no explainable reason. Though to be fair, this is also the result of bad writing in the episode he appears in, and the fact that a lot of important scenes were cut from said episode, presumably due to time constraints doesn't help in the slightest.
 * 3) He fooled Frankie and Mr. Herriman and convinced them to take his side over Bloo, Coco, Wilt & Eduardo with his made-up sob stories, making them both additionally out-of-character.
 * 4) * Worse still, his acting skills of making up sob stories is very poor and unconvincing, so much to the point that each time Frankie and Mr. Herriman fall for it, it makes the two look like complete idiots.
 * 5) Whenever he is about to cause a misdeed, or most infamously, gets anyone in trouble and gets off scot-free after that, he makes an evil and downright cruel grin which is extremely punchable.
 * 6) Near the middle of the episode, Bendy acts very mean-spirited to Bloo; the worst example is during the intercom after poor Bloo gets banned from doing his favorite things until further notice. To make matters worse, he uses Bloo's toothbrush to clean the toilet, which is outright disgusting.
 * 7) His voice is very irritating, whiny, and ear-piercing, such as in the annoying scene where he and Bloo tried making a louder laugh at each other, and also, he fake-cries in front of both Frankie and Mr. Herriman to be spared from any punishment whatsoever.
 * 8) He never gets any comeuppance for framing the others out of malice and gets off scot-free at the end, which makes him a Karma Houdini.
 * 9) While his design is decent (as formerly mentioned in then-RQ#3), it looks like a rejected design for The Grinch.

Redeeming Qualities

 * 1) He did get initially scolded and blamed for flooding the house, which is perfect karma until Bloo ruined it.
 * 2) Depending on your view he can have some funny moments, such as getting ink on his face when he uses the pen and having a laugh battle with Bloo.
 * 3) He thankfully gets his comeuppance for his actions in Imagination Invaders, by getting scolded.
 * 4) Despite being annoying, his voice is decent, thanks to Jeff Bennett voicing him.
 * 5) As mentioned below, he hasn't appeared in Foster's Home for Imaginary Friends since his debut episode and (to a lesser extent) Imagination Invaders, so, we won't have to worry about him making any more appearances or causing any more trouble again.

Reception
Bendy's cruel actions have been widely criticized by fans, especially when he expresses them to a certain favorite character. Due to this, he was completely removed from the show. Lauren Faust, the wife of the show's creator, Craig McCracken, apologized to fans for making "Everyone Knows It's Bendy".

He, Jamze Withazee and Goofball are considered to be three of the most hated characters in the show, even surpassing both Bloo and Duchess combined.

Trivia

 * He is the first character in Foster's Home for Imaginary Friends to be written out of the show, and is classified as a 100% non-canon character. The second and third characters are Goofball McGee and Jamze Withazee in that order.
 * Despite not appearing in any other episode of the show, Bendy's signature was seen on Mac's 'Goodbye' card in the series finale of the show, "Goodbye to Bloo", though it might be another character who's also named Bendy.
 * Despite him appearing in one episode, he has been featured in other Foster's Home media unlike the show. In the mh:awesomegames:Game Boy Advance game, he appears as an enemy where he throws items at the player. In the mh:crappygames:Leapster game, he steals Cheese's horse and causes Bloo to go on a quest to stop him. In the mh:awesomegames:Nintendo DS game, Imagination Invaders, he breaks some busts and draws on a wall, but then, Bendy gets caught by Bloo. Unlike in the show, he got his comeuppance for what he did by being scolded.
