Everybody says there's nothing more dangerous than a mother protecting her young — but some moms go way above and beyond, in their ambition and grit. Some mothers are just unstoppable. But who's the baddest mother in all of science fiction or fantasy?

Please include a picture, poster, book cover, comics panel or clip for your chosen mom. And please mention her name, where she appears, and why she's so formidable. Thanks!
