Artist Butch Hartman, the creator of multiple Nickelodeon shows like the Fairly Odd Parents, T.U.F.F. Puppy, and Danny Phantom, is being accused of plagiarizing art by a Japanese artist. Hartman, who charges upward to $200 for a commission, was accused by a Twitter artist simply known as 028ton as tracing their piece of Attack on Titan character Mikasa Ackerman.

　　I have received a report that my fan art has been plagiarized.

　　I checked the tweets and found many similarities to my work. In addition, there was a possibility that money was being made, so I am urgently alerting you to this.

　　"They do not have permission to use the illustrations," the artist tweeted. "If you see any products using the same artwork in the future, please do not purchase them."

　　Butch Hartman was soon trending on Twitter with over 70,000 tweets talking about him. It was even pointed out that Hartman has been accused of this in the past. Older instances of Hartman's plagiarism started to resurface, including him tracing Ran-chan from Urusei Yatsura.
