Update 3: The last of the teasers shown at SDCC 2010 is finally here for all to see, and it's the most surprising: Kraven the Hunter. Dead for years, having killed himself, Sergei Kravinoff was recently resurrected by members of his family. One of Spider-Man's most dangerous foes, it can certainly be said that he, above probably all other 4 candidates, has no fear. Perhaps he is ready to trade the trees for the urban jungle.
Update 2: Falcon is one of Captain America's dear friends. Sam Wilson has the distinction of being the first African-American mainstream superhero, but he's better known for simply being a frequent team-up with Cap, or a member of the Avengers. With his dual pasts, thanks to a cosmic cube, as a Harlem-born gangster and as a social worker, he's easily the ideal candidate to take over watching over Hell's Kitchen, if that's what these teasers imply. His bird's-eye views over the city should help snuff out crime, and strong connections to both the Avengers and S.H.I.E.L.D. would make calling in assistance pretty easy.
He was preceeded as a black hero however by The Black Panther. T'Challa is the most well-known to hold this mantle, and is most likely the one shown in this picture. His sister, Shuri, has been the primary Black Panther of late in the comics, however. With his tight ties to his home country of Wakanda, the ficitonal African nation he rules alongside X-Man Storm, it seems he's a pretty unlikely possibility for someone who would watch over a single neighborhood of a single city in a single state in a country halfway across the world from home.
Update 1: As predicted, next up is Gambit. The Rajun Cajun has a lot to fear, and a lot he can face. For the last few years, he's been Apocalypse's latest avatar of Death. Of course, other X-Men have been in that position, and overcome the control and urges of En Sabah Nur, so it's possible Remy LeBeau could as well.
He has his own past to deal with, too; from his time as a thief, his time with Sinister's Marauders, and his tumultuous relationship with the Southern Belle, Rogue. So, is he the new Man Without Fear?
Original Story: Marvel released a new teaser image Monday, and if history is any guide, the first in a teaser campaign.
This one simply asks “Who Will Be The New Man Without Fear?”, adding “Shadowland brings a major change to the Marvel Universe!”
During the various Marvel panels at Comic-Con International: San Diego 2010, the company showed off teasers touting several possible new "Man Without Fear" candidates; now they're starting to release those images to the general public. Besides Nova, we'll be looking forward to sharing Black Panther, Kraven the Hunter, Gambit, and Falcon; those were the ones shown at the show, though others could come out now as well.
Expect images teasing other candidates – likely and unlikely - over the next several days and/or weeks.
