Latest Late-Night Host to Come Under Fire: Conan O'Brien Slammed for Tweet About Muslim Marvel Superhero

Twitter is not Team Coco at the moment.

Conan O'Brien recently came under fire for posting a tweet about Marvel's new Muslim superhero. Many Twitter users found his attempt at a joke "racist" and offensive, and the backlash was so extreme that O'Brien deleted the tweet.

Before it was deleted, the tweet read: "Marvel Comics is introducing a new Muslim Female superhero. She has so many more special powers than her husband's other wives."

O'Brien's comment angered quite a few of his 9.2 million followers, as well as other Twitter users, who pointed out that the Muslim superhero is a teen girl from New Jersey and not a housewife. In the series Kamala Khan, who takes on the name Ms. Marvel, is a typical 16-year-old whose religion doesn't play a major role. (Kamala got the Ms. Marvel title after the previous holder took on the Captain Marvel role herself.)

Kamala isn't the first Muslim superhero to get a comic series — Lebanese-American Simon Baz became DC Comics' new Green Lantern a couple years ago. But Kamala's introduction to the Marvel universe is generating praise and excitement among fans.

The new Ms. Marvel has already achieved hit status. "Captain Marvel No. 17," which teased a glimpse of Kamala discovering her superpowers, sold out and is getting a second printing.

O'Brien isn't the only late-night host who is the target of angry backlash. ABC's Jimmy Kimmel is also at the center of a controversy, with protesters calling for his firing after he aired a segment called "Kids' Table" in which a young child suggested that they "kill everyone in China."

Kimmel apologized to upset Chinese-American groups, saying, "I just want to say I am sorry. I apologize. It was certainly not my intent to upset anyone."

But his apology didn't smooth things over, and a petition to the White House to hold Kimmel and ABC responsible has garnered over 100,000 signatures, which requires an official response from the administration.
