|First appearance||Billy & Mandy's Big Boogey Adventure|
|Voice actor||Grey DeLisle|
Mandroid was a robot version of Mandy but malfunctioned because after she cornered Billy, Mandy, Irwin and Grim, she aimed a laser at them and said, "Please surrender yourselves and come with me. You will be assimilated." Mandy told her that if she is supposed to be her, that means she doesn't say "Please," she doesn't assimilate, and she doesn't take orders from anyone, including the Boogey Man. She then malfunctioned because she was ordered to not take orders, which was a contradiction, and thus she did not know what to do.
She had a hand that could transform into a cellphone. In the end, Mandy and Mandroid seemed to become friends, or at least develop a grudging admiration for one another. Mandroid became like Mandy in the same fashion that Billybot became like Billy. They forced Creeper to be their slave at the ending of the movie.
- Like Billybot, Mandroid has a themed flaw in speech due to being a robot.
- She often will confuse binary (1 and 0) as common day English, and when malfunctioning she constantly repeats the code, though no one is expected to translate it (Note: Binary is an official language and is used to program things like computers, and can be learned, though it is the most complex language known and would take, maybe, an entire educational career (15 to 20 years) to complete it, and about a month to translate Mandroid's sentences without training).
- In Fusion Fall, Mandark's robots are also called Mandroids.
- Her & Billybot were costumes for Billy and Mandy in the games The Grim Adventures of Billy & Mandy video game and Cartoon Network: Punch Time Explosion (Console version).
