Well, I just read online that one of the most iconic fictional characters in American pop-culture has just renounced his U.S. citizenship.

In the Action Comics #900 issue (2011 April), which has a cover price of US$5.99 (about ¥486) by the way, Superman announces his plan to give up his American citizenship.
