Erma (webtoon)

Erma is a comedy horror webtoon and animated web series created by Mexican artist Brandon J. Santiago. It follows the adventures and misadventures of the titular initially six-year-old Erma Williams' experiences as a half-human, half-yōkai/ghost, tending to use her haunting abilities for everyday antics, whether for better or for worse, focusing on themes such as friendship and acceptance. Santiago initially published the webcomic on DeviantArt and Tumblr in May 2014, but has since released it on various services from January 2016, such as Tapas and WEBTOON. It is available in two languages, English and Spanish. In January 2020, Comics Beat reported that with 64.5 million views and 74.9 thousand subscribers, Erma was the most-viewed webcomic on the Tapas syndicate in 2019.

In October 2017, Santiago published a prequel graphic novel to the series titled Spirit's Bloom, as well as two anthology collections of Erma comics, in addition releasing a short film pilot of Erma produced by Outcast Studios. A print collection, Tales of Outcast, was released in March 2019. Other works include the stand-alone Night Detective, Siris, and Warrior Unicorn Princess, and Yokai, an in-universe novel. A picture book, Meet Erma, was released in April 2020. An Erma animated series began releasing to YouTube from July 2024 to present.
