London: Superman, one of the most iconic fictional characters, has created a furor by renouncing his US citizenship in a latest issue of the comic book.

The superhero known as a champion of truth, justice and the American way forsaking his US citizenship in the Action Comics' record 900th issue this week, a daily reported.

Superman makes the move after being caught in the middle of a diplomatic row between the US and Iran.

The storyline has enraged some fans who claim it is a slight on the US.

"Besides being riddled with a blatant lack of patriotism, and respect for our country, Superman's current creators are belittling the United States as a whole," Hollywood publicist and Republican activist Angie Meyer was quoted as saying.

"By denouncing his citizenship, Superman becomes an eerie metaphor for the current economic and power status the country holds worldwide," she added.

In the story, Superman is criticised for making an appearance in Iran to support the country's rebel protests. It follows the comic book trend of mirroring real life events.

But it is still a radical departure for the character first created in 1938 by Jerry Stiegel and Joe Shuster, a daily reported.

DC Comics co-publishers Jim Lee and Dan Didio insisted the superhero is not turning his back on America.

"Superman is a visitor from a distant planet who has long embraced American values. As a character and an icon, he embodies the best of the American Way," they said in a statement.

"In a short story in Action Comics 900, Superman announces his intention to put a global focus on his never ending battle, but he remains, as always, committed to his adopted home and his roots as a Kansas farm boy from Smallville," the statement added.

He is not the only comic book character to be influenced by politics. Captain America briefly hung up his boots as he was frustrated with the level of corruption before making a comeback.
