Shogun Warriors was not a good comic, and I’m going to say that it is not canon, despite the fact that The Fantastic Four appeared in the final two issues. And the closest thing to a Shogun Warrior that ever appeared in a different Marvel Title, was the giant robot warrior Red Ronin, who first appeared in Godzilla–not this book–and then appeared in The Avengers #198-199.
But since there’s an FF appearance, I’m covering it here. But I’ll confess: I did not read every issue of this book.
