Judith "Judy" Neutron is a supporting character from The Adventures of Jimmy Neutron Boy Genius. She is Jimmy Neutron's mother, Hugh Neutron's wife. Unlike her husband, she is strict, overprotective, and a neat-freak.
She was voiced by Megan Cavanagh.
Judy is tall and skinny, a beautiful 50s housewife style woman. She has brown hair in a 50s style hairdo and beautiful green eyes. She wears jumbo gold hoop earrings, wears a green sleeveless dress with small pink polka-dots, along with a white pearl necklace. Judy wears green high-heel dress shoes, wears red lipstick, and has a mole on the right side of her face. Her nails are polished with pink nail polish.
In Jimmy Neutron: Boy Genius, Judy sometimes wore a white apron.
Judy is quite intelligent, and is implied to be where Jimmy got his genius intellect from. She has saved Jimmy and his friends from danger on more than one occasion. After Jimmy created a robot called the Maternotron to replace Judy while she's on vacation, Judy arrived just in time to defeat the robot after it became overbearing and dangerous. During this incident, she is shown to have inventions of her own, pulling a highly advanced blasting ray out of the closet to put an end to the Maternotron. She was also able to track Jimmy and his friends after they get lost during a camping trip due to a tracking device she put in Hugh's skin.
In the Jimmy Timmy Power Hour, Timmy Turner hypnotizes Judy and makes her believe she is a superhero named Mighty Mom. While in a trance, she believes she can fly, and runs around the house cleaning up dust bunnies and Hugh's ducks.
