If the life of Stan Lee were turned into a superhero movie, it would be difficult to tell the good guys from the bad.

A battle over the Marvel Comics legend’s legacy is underway, featuring a cast of characters whose competing agendas make the plot of “Avengers: Infinity War” look simple by comparison. A man who says he is Lee’s manager and caretaker was arrested this month in Los Angeles on suspicion of filing a false police report and is being investigated over alleged elder abuse, according to court filings. A court has placed Lee, 95, under the temporary guardianship of an attorney, who has received a restraining order against the manager.

Since his wife, Joan, died last year at age 93, Lee has found himself surrounded by people with unclear motives and intentions, friends and colleagues say. The decline of his private life stands in stark contrast to the soaring success of Marvel, the brand he helped to create five decades ago. The blockbuster movie adaptations released by Disney’s Marvel Studios are perennial box-office winners that have helped to keep Lee’s influence thriving among new generations.
