"Spider-Man and Zoids", before later starting "Incredible Hulk Presents" which ran a hodge-podge of US material.
Now that you mention it, I had those two. Completely forgot/ignored the Spidy for the Zoids, of which I still remember some storylines.
Incredible Hulk Presents also had one UK element - a UK Doctor Who strip in Black and White. Only ran for 12-13 issues.
I never had the Marvel Star Wars ones though, its heyday must have been just before my collecting days (December '85)
I never had any non-marvel ones either.
