The Jonkler is a central figure in the ironic and surreal humor of the r/BatmanArkham subreddit, representing a deliberately misspelled and unhinged version of the Joker. Emerging from the 'Aslume' era of the community, the character is often associated with absurd shitposts and the repetitive rhetorical question, 'Is he stupid?' The meme typically features a distorted or low-quality image of the Joker, highlighting the perceived descent into madness of a fanbase waiting for a new game release. Today, The Jonkler is a staple of internet brain-rot culture, used to satirize confusing situations or to celebrate the sheer absurdity of online fandoms.
