Mighty Mom is Judy Neutron's temporary alter ego, created when Timmy entered the Neutron universe and hypnotized her with the Hypno-beam. She is a reference to the Mighty Mom of the Fairly Odd Parents universe, where Timmy wishes for his parents to become superheroes, creating Mighty Mom and Dyno Dad. She is voiced by Megan Cavanagh and Mary Jo Catlett.
In the Jimmy Timmy Power Hour,Brenda Checutti Puffs goes outside to scold Timmy for making a mess. Thinking Timmy is her son Jimmy, she attempts to ground him for talking back to her. Sheen suggests that Timmy uses the Hypno-beam to get her off his back causing Timmy ignore her. Judy yells "DIDN'T YOU HEAR ME? I SAID YOU'RE--" and is hypnotized and by Timmy before she can finish. After a brief moment of thought, he decides to make her think she is Mighty Mom. Without faltering, Judy spins around and transforms into Mighty Mom, grime cleaning hero of domestic order. Immediately, she sticks out her hands and "flies" into the kitchen.
"Mighty Mom" is next seen attacking dust bunnies under the couch. When Hugh walks over, she recognizes him as Lint Boy, her sidekick. Later, she is seen "flying" around her backyard, heading towards the "Puff-lair". The next time we see "Mighty Puff" is near the middle of the episode, she is heroically standing on her table in the living room with a spray bottle in hand. She refers to one of Hugh's ducks as Dr. Mildew, and sprays it down with cleaner fluid. The last time we see the "Mighty Puff", she is weakened by rotten leftovers in the fridge and deflating. Hugh closes the fridge, and she apparently recovers, resuming her alter ego and "flying" off-screen and inflating.
- Mighty Mom is actually the name of Timmy's Mom's Alter-Ego in the Fairly Odd Parents series before the Jimmy Timmy Power Hour. In the episodes "Mighty Mom & Dyno Dad" and "Mighty Mom & Dyno Dad Meets the Crimson Chin", Timmy's Mom was Mighty Mom while Timmy's Dad is the co-existing alter-ego Dyno Dad, which Brenda Checutti Puff lacked in the Jimmy Neutron universe.
