Hester Bachmann-Turner is Gus's mother and a minor character in the animated TV show Robotboy.

Unlike Gus, she and her husband, Jebediah, are Amish, and forbid things such as technology, which probably resulted in Gus's obsession to video games and other stuff. When Gus is around them, he acts well behaved and respectful, unlike his true, mischievous self.
