The toy company was KNICKERBOCKER TOYS. They called their toy property, based on technology licensed from a Japanese company, the “MYSTERIONS.”
Marvel Comics was their second choice as a creative services provider. They had gone to DC Comics first. The executive who approached us showed us what DC had created for them. It was a comic book. He only had photocopies. I don’t believe the thing was ever printed.
It was awful. Apologies to whomever created that thing, but it was pathetic and wrong-headed to an unbelievable degree. The art was well-drawn, I’ll allow that, but the storytelling was chaotic. The story, as best one could discern it, was unnecessarily, excessively dark and violent. The dialogue was peppered with “Hells” and “damns,” and I can’t swear to it almost 30 years later, but I think there was a “bastard” or two in there.
