Same thing goes for 80's Marvel TF comics. Can't change IDW canon, or Marvel TF canon. I'm guessing you don't like licensed characters in Marvel, guessing by your discussion on that Spider-Man/Red Sonja crossover. Thing is, there are a few licensed characters exist in Earth-616 like Godzilla, Tarzan, and Conan the Barbarian.

The main exception is Transformers, which as far as I can tell, don't exist on Earth-616. Neither the US or UK Marvel Transformers comics take place on Earth-616, and the IDW crossover can't take place on Earth-616 due to the presence of Doctor Doom, who was in Hell when the crossover took place.
