Fun Fact: DC and Marvel in put together and co-published for Amalgam Comics, an imprint which featured combinations of their respective heroes much akin to this. It featured Heroes such as:
Dark Claw (Batman/Wolverine)
Doctor Strangefate (Oddly enough, Not Stephen Strange, but Charles Xavier/Dr. Fate lolwut),
Super Soldier (Captain America/Superman)
Amazon aka Ororo of Themyscira (Storm/Wonder Woman)
and many more.
Nothing but Props to the artist, but I think some of these mash-ups aren’t very suitable. Though I guess that’s the very nature of mash-ups. Some are hits, some are misses. Great art either way. Wonder Phoenix, Captain Crawler and Flashulk are next level rad though.
