Every day this month, I'll give you a new cover theme game! If you don't know the game by now, it works like this: I'll show you three covers. They all have something in common, whether it be a character, a trait all three characters share, a locale, a creator, SOMEthing. And it isn't something obvious like "They all have prices!" "They all have logos!" "They all feature a man!" "They are all Avengers (who ISN'T?)!" "They're all dead (who HASN'T been killed off?)!" etc.
In addition, please note that you must have some familiarity with comic book history to correctly guess these comics. You cannot guess the connective theme just by looking at the covers solely, you must have some knowledge beyond just the covers.
If you come up with an answer that works outside of what I intended, I'll give you credit (well, provided I think it fits, of course).
One more thing - if there are floating heads on the cover, ignore them! They don't mean anything!
If you think you know the answer, e-mail me at email@example.com (make sure to write which number game you're answering). Don't answer in the comments. This way, people who check in at different times of the day can still get credit for answering it correctly! After two days, I'll post the people who answered today's game correctly! Here is the list of all the games, along with the answers to each one (after two days go by, of course).
Good luck and enjoy!
