Jimmy Nutrin
The son of Hugh and Judy Nutrin. Boy genius that the short revolves around.
- Art-Style Dissonance: He is given a realistic body, but cartoonish eyes and hair.
- Child Prodigy: Though he doesn't get to show it in the short.
- Nightmare Face: The last shot of the video shows his eyes bulging wide open, with his lower lip covering his upper one.
- Sudden Sequel Death Syndrome: Is dead by the time of Jimmy Neutron Happy Family Happy Hour 2, being buried in the "Dead Joke Cemetery". He’s also dead in A Neutron Family Christmas, though it remains unknown if this video takes place in an Alternate Continuity or after the sequel.
- Younger Than They Look: Jimmy is still evidently a kid, but resembles an adult.

Jimmy's father and Judy's husband. He drives the plot forward.- Abusive Dad: He kills Jimmy's mother for no reason. Then he forces Jimmy at gunpoint to watch TV with him.
- Adaptational Villainy: Canon Hugh Neutron is a kind eccentric. This version, on the other hand, is a crazed, murderous psychopath.
- Alas, Poor Villain: The Christmas video shows him having fallen into depression after he killed his wife and his son died. It's hard not to feel some pity for him when he is implied to commit Suicide by Cop.
- Art-Style Dissonance: He is given a model that looks like it was designed by a amateur animator. That is, until A Neutron Family Christmas.
- A Sinister Clue: He seems to be left handed, as he always has his gun in his left. He does hold an axe in his right hand in the Christmass video though, so he could be ambidextrous.
- Back for the Dead: He gets killed by the police for murdering Ebenezer Wheezer in A Neutron Family Christmas.
- Back from the Dead: Is alive in A Neutron Family Christmas, but Judy and Jimmy are not. He is killed by police for the murder of Ebenezer Wheezer.
