Alright, lots of links in case you don't have the polymathic geek background that's determined my mentality:
I might have neglected to post a link to "the Watcher" before: http://en.wikipedia.org/wiki/The_Watcher_(comics)
Here's what Earth-616 is: http://en.wikipedia.org/wiki/Earth-616
And if you don't get how a beard is all you need to be evil: http://tvtropes.org/pmwiki/pmwiki.php/Main/BeardOfEvil
(The usual caution about TV Tropes devouring your day is offered here.)
I guess tomorrow we get to find out who is evil? OO-A'2 seems like a rather big guy, the same kind of big seen in Futurama when LRRR from Omicron-Persei 8 visits Earth: he seems to dwarf everyone on the planet.
