(CNN)In cities around the world, among the sea of demonstrators who have taken to the streets, one image has stood out: the stark white face and creepy red grin of the Joker.

Artists in Lebanon and Iraq invoked the character on posters or edited him into images on social media.

Someone spray-painted "we are all clowns" onto a statue in Santiago, Chile.

And in Hong Kong, protesters dressed as the Joker as an act of protest in itself, defying a government ban on face masks and face coverings during public gatherings.

Their causes are different, their grievances varied. Proposed austerity measures. Threats to democratic freedoms. Deepening inequalities between ordinary citizens and the ruling elite.

So why are some protesters in Lebanon, Iraq, Chile, Bolivia, Hong Kong and Spain taking inspiration from a psychopathic killer from a controversial film?

Some see themselves in the Joker

"The Joker is us," Lebanese street artist Mohamed Kabbani told CNN. "... Beirut is the new Gotham City."
