The #RedrawReigen meme, also known as the Reigen Arataka Redraw Challenge, first exploded on Twitter in late 2016 following the popularity of the Mob Psycho 100 anime. It involves artists and fans redrawing the self-proclaimed 'Greatest Psychic of the 21st Century' in various humorous situations, often referencing other iconic memes, movie posters, or pop culture moments. The meme highlights Reigen's versatile personality as both a comedic con artist and a surprisingly heartfelt mentor. Today, the hashtag remains a staple in the anime community, used whenever a new funny pose or screenshot emerges that perfectly fits Reigen’s dramatic and expressive character design.
