The 95-year-old co-creator of many Marvel superhero characters, including Black Panther and Spider-Man, alleges he was duped into signing a fraudulent agreement that gave POW! exclusive rights to his name, identity and likeness.

According to the lawsuit, Lee was unable to read the document due to his eye condition, and he doesn’t remember anyone reading it to him, suggesting that his signature may have been forged, copied or induced.

“In addition, POW! took control of Lee’s personal social media accounts, including Facebook, Instagram and Twitter, thereby impersonating Lee before a combined 15 million followers worldwide,” the complaint reads.

There has been no response from POW! Entertainment to the lawsuit. But in April, the company issued a statement expressing concern for Lee amid reports that he was the victim of elder abuse.

“We at POW! Entertainment take great pride in our continuing work to create exciting new Stan Lee content and characters as well as safeguarding the legacy of the greatest storyteller of our time,” the statement said.

“We are also fans and share the heartfelt admiration and love of the community who have voiced their sincere concern for Stan’s wellbeing.”

There were more negative headlines when it emerged last month that Lee was being sued by massage therapist Maria Carballo for sexual assault and battery. She accuses him of inappropriate touching and misconduct during two sessions last year in Chicago.

Lee’s attorney Jonathan Freund has denied the allegations to the Chicago Tribune newspaper.

Lee has faced a similar claim before. In January, the Daily Mail reported on allegations of sexual assault and harassment by nurses who cared for Lee at his Los Angeles home.

Lee’s representatives denied those allegations.
