Julia Brain

[SFW opening] J-37, better known as Julia and Julia Brain when married to the Brain is a recurring antagonist within the Pinky and the Brain segments of the Animaniacs reboot. Julia has brown fur on her back and a yellowish underbelly, as well as a brown spot around her left eye. Initially a well meaning and caring mouse who disapproved of the abuse Pinky endures, she eventually becomes the Brain's worst rival. Due to a malfunctioning mind controlling-device connected to her cerebrum, her personality now incorporates both Pinky's insanity and the Brain's calculating nature.
