Momo is a popular character from a viral internet meme that originated from a sculpture created by artist Keisuke Aiso. The sculpture features a distorted face with bulging eyes and a wide, unsettling smile. It gained notoriety in 2018 when it was falsely linked to a social media challenge that allegedly encouraged harmful behavior among children. The image of Momo is often associated with horror and urban legends, leading to widespread fear and misinformation. Despite its frightening appearance, Momo is not a real entity but rather a fictional creation that has been used in various forms of media, including YouTube videos and social media posts.
