Momma Robotnik

"Robotnik in a dress?!" ~ Sonic

"No, that's Mama Robotnik - she's even worse!" ~ Tails

Mama Robotnik is arguably one of the most evil villains in the cartoon series Adventures Of Sonic the Hedgehog: the large, intimidating and geniunely insane mother of the infamous Dr Robotnik she spends much of her time locked up in what can only be assumed is a psychiatric ward but sometimes escapes and wreaks havoc in the crazy world Sonic and Tails inhabit.

Mama Robotnik is so insane that she even scares her own son and although just as comedic as the others in the show she was definitely wicked, in fact she showed little care even for her son and was actually fairly abusive towards him - her only true goal in life seems to be to destroy Mobius and make everyone miserable.
