Bendy (Foster's Home for Imaginary Friends)

Bendy is a one-time character from 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 were after poor Bloo gets banned from doing his favorite things until further notice, Bendy uses Bloo's toothbrush to clean the toilets, which is uttery mean, not to mention 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.
 * 10) What makes him especially infuriating is that much like Sarah (from Ed, Edd n Eddy), Rodrick Heffley (from the Diary of a Wimpy Kid book series) and Micah Brill (from the Goosebumps book Revenge R Us), he has no good reason as why he acts this way or why he got Bloo and his friends in trouble other than because he can.

Redeeming Qualities

 * 1) He did get initially scolded and blamed for flooding the house, which is perfect karma until Bloo ruined it.
 * 2) 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, and also in his episode when Bloo unleashed his plan onto him.
 * 4) Despite being annoying, his voice is decent, thanks to Jeff Bennett voicing him.

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 Game Boy Advance game, he appears as an enemy where he throws items at the player. In the Leapster game, he steals Cheese's horse and causes Bloo to go on a quest to stop him. In the 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.
