"Loan."

In the 70's, Conan the Barbarian (and to a lesser extent, Red Sonja) were licensed by Marvel but were de facto Marvel characters: they appeared in a lot of ads and promo stuff. Although, I don't think either ever got a Hostess ad? Later, with the exception of Transformers #3, licensed hits like Transformers and G.I. Joe were siloed off from the main Marvel Universe. So was Alf, although it had a lot of parodies, like the X-Melmen. Really seems like there should've been a Hostess parody in there somewhere, too.
