He-Man started out as a line of action figures to accompany the feature film Conan, but manufacturer Mattel didn’t think Arnold Schwarzenegger’s character was a suitable role model for young children—how right they were. The toy line was considered a bit of a risk at the time since boys weren’t known to play with dolls, but in 1985 the line earned over $400 million dollars, out-earning even Barbie.
