The official Bert Is Evil website has been removed from the Internet.
Its creator made the decision after images of the Sesame Street puppet surfaced on banners held by demonstrators in Bangladesh protesting against the bombing on Afghanistan.
The picture of Bert with Osama bin Laden is thought to have come from a Bert Is Evil copycat site. Dino Ignacio started the Bert Is Evil cult, reports EOnline.
He was the first to digitally pair the character with evil people as a joke. Bert has also been pictured with Hitler, the Ku Klux Klan, the Unabomber and Jeffrey Dahmer.
Ignacio's site won awards and spawned a series of spin-off and mirror sites. He is now asking other sites to close down as well.
"I am doing this because I feel this has gotten too close to reality and I choose to be responsible enough to stop it right here," he said.
