Jimmy Fallon may have been expecting Kristen Wiig as a guest on The Tonight Show Wednesday, but he got Khaleesi instead.

Wiig showed up in full costume as Game of Thrones' Mother of Dragons, complete with a toy dragon glued to her shoulder.

Among the personal info "Khaleesi" shared: Her real name is Karen, and she lives in the forest, in a dome on top of a mountain. Also, she only speaks in a British accent part of the time, and has been dabbling in stand-up "about rocks and, like, swords and stuff."

Wiig previously appeared on Fallon's Late Nightas Michael Jordan in 2013 and as Harry Styles last year on The Tonight Show.
