@Rebelofnj,
Marvelman was a shame. With hindsight the similarity to Captain Marvel with the body swapping stuff was too much, but it was based on an early British comic character of the same name.
Your comic industry seems far more successful than ours. Our most successful comic is a parody of most British comics from the 70s that now have gone.
We never really had single character comics except for occasional one offs. Most British comic characters appeared as strips in comics like Beano, Dandy, Whizzer & Chips, and more action comics like Lion, Thunder, Valiant and ultimately 2000AD.
We did have some superhero figures, but they were a bit lame. This is Billy the Cat from The Beano.
Usually though our characters, even those with special powers, weren't seen as superheroes, although they probably would if imagined your side of the pond.
The Spellbinder is similar to Dr Strange, but is in a very different universe.
Again with Janus Stark, special powers but not a superhero.
