"Astro-Girl's snoring was very loud! JUST LIKE ALISA'S SNORING!"
— Evil-Man's statement about Hannah Morgan's snoring.

Hannah Morgan, who is referred to Evil-Man as Astro-Girl, was a character on Barney & Friends from Seasons 4, 5, and 6, as well as a minor character during Barney and the Rocko Squad.

Hannah is one of Evil-Man's half-enemies during Barney and the Rocko Squad, because in the eighth Barney and the Rocko Squad episode, during the third clip, she was snoring as loud as Alisa Bosconovitch, Ling Xiaoyu, and other female characters in the Rocko franchise. She is the only child to return in Barney and the Rocko Squad's main footage alongside Kathy and Min; though they will all have a sleeping habit.

Marisa Kuers voices Hannah during Barney and the Rocko Squad.
