Martian Leader

The Martian Leader appears in Episode 4805 of Sesame Street.

She sends two of her subjects to Sesame Street to find out what Earth people are like. She communicates to her explorers holographically via a Martian communication device. Elmo shows the Martians all around the street, where they see Earth people can come in all shapes, sizes, colors and languages. With all this intel, the Martian Leader ponders if Earth people can still get along. Elmo helps them make friends with everyone to show it's possible.

She also appeared in a 2017 video for the show's Spread Kindness, Share the Laughter campaign.
