Bendy (Foster's Home for Imaginary Friends)

Bendy is a minor character from Foster's Home for Imaginary Friends and the main villain of the episode, "Everyone Know's It's Bendy". He is a trouble maker who always likes to do bad things and blame others for it.

Appearance
Bendy is a black and yellow imaginary friend with curly hair on the back of his head. Whenever he successfully blames someone else for his evil-doings he gives them a creepy grin while others are not looking.

Personality
Bendy appears to be very skilled in deception. He managed to easily fool Frankie and Mr. Herriman into believing others commited his actions. This is mostly due to the fact his family left him at the home for bad actions he did (though it might have actually been the couple's son). Since then he was able to trick the two by using a fake sob routine. He always somehow managed to cover his tracks, and even got off scot-free when Bloo flooded the house in an attempt to expose him.

Also, Bendy is also a gigantic coward, as he uses his crocodile tears to convince Mr. Herriman and Frankie to that he didn't commit the acts he did and haphazardly sets off Bloo's traps when he is nearly exposed.

Is He Really Evil?
Bendy may have just been misunderstood and because of that may have become the mean trickster he is. But his actions got worse over time and he fakely complimented Frankie and Herriman only to talk bad about them behind their back. Bendy may actually be evil though, since his grin is incredibly sinister everytime. Also he never stops what he does. He is shown getting away with everything he does wrong.

Trivia

 * Unsurprisingly, Bendy is considered to be one of the worst characters in the entire series. Even Lauren Faust has regretted ever writing the episode.
