Joe!
Do other countries have their own super-hero teams? We know that there are people with powers from other countries because they always end up in our American hero teams. I mean there's gotta be villains in other countries right? Wouldn't other countries want their own "Avengers" team? Does S.H.I.E.L.D just deal with the United States?
JQ- Chris, of course other countries have super heroes. We've seen some of the other heroes and teams that are active worldwide, including Alpha/Omega Flight in Canada, the Winter Guard in Russia, MI:13 in the UK (along with the more covert ClanDestine), and Big Hero 6 in Japan. Invincible Iron Man 2 introduces the Triumph Division, the super-team of Manila, in just a few short weeks. And S.H.I.E.L.D. is an international organization, so they operate on a global scale, though they're mostly funded and staffed at the executive level by Americans.
By the way, since I mentioned them, Big Hero 6, the top heroes of Japan, are about to come back with their own miniseries by Chris Claremont and David Nakayama. David's been hard at work redesigning the returning characters, as well as two new members to fill out the team's ranks.
