Bendy (Foster's Home for Imaginary Friends)

Bendy is a one time character from Foster's Home for Imaginary Friends. Appearing 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 He Sucks

 * 1) For obvious starters, he caused trouble all over Foster's and is a bad part of the episode he comes from.
 * 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 on the episode he appears in, not helping is the fact that in said episode a lot of important scenes were cut presumably due to time constraints.
 * 3) He made Frankie and Mr. Herriman unlikable jerks and idiots by making them take his side over the guys at Foster's with his made-up sob stories, making them 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 gets anyone in trouble, he makes his infamous smile.
 * 6) His voice is very horrible, whiny and ear-piercing, such as the annoying scene where he and Bloo tried making a louder laugh at each other and every time he fakes cries in front of both Frankie and Mr. Herriman to be spared from any punishment whatsoever.
 * 7) He constantly cries to both Frankie and Mr. Herriman in order to escape karma and to pin the blame on others, which gets really annoying after a while.
 * 8) He is characterized as a troublemaker who wants to put everybody through hell, and ALWAYS succeeds at doing so.
 * 9) He never gets punished for framing the imaginary friends at Foster's out of malice and gets off scot-free at the end. This makes him a karma houdini.

Redeeming Qualities

 * 1) His design is pretty decent, but not that great.
 * 2) He did get initially scolded and blamed for flooding the house, which is perfect karma until Bloo ruined it.
 * 3) He thankfully only appeared in one episode and never appeared again.

Reception
Whenever Bendy is about to frame an imaginary friend and gets off scot-free after framing said imaginary friend, he makes a very slimy, evil, and downright cruel grin; that in particular has been WIDELY criticized by fans for being horribly obnoxious, especially when he does this to a certain favorite character of fans. Due to this, following the episode he appeared in, he was completely removed from the show. Lauren Faust apologized to fans for making Everyone Knows It's Bendy.

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