Years ago, back in the 1970's, the great science fiction author Philip Jose Farmer wrote an essay stating that the DC and Marvel universes were actually one and the same, it was just the commercial separation of the two companies that "artificially" made them look separate. In particular, he suggested that it was obvious that Captain Boomerang and Boomerang were the same person, differentiated only for copyright reasons.
Of course, Farmer was totally obsessed with pulp fiction continuity. He worked out an elaborate "secret history" showing how Tarzan and Sherlock Holmes were ancestors of Doc Savage, and how virtually all of the major heroes of pulp fiction were descended from a single British family who had been exposed to a radioactive meteorite in the mid-19th century.
Thanks for all your work with this "Little Friends" project. It's quite a pleasure to see new works everyday in such good quality! By the way, Emma Frost and Killer Frost would be real nice to see. And they don't have anything in common with cats, so it will be a real fresh!
