Martin Brisby is the strongest and the eldest child of Mrs. Brisby and a neutral character in The Secret of NIMH and the main antagonist of The Secret of NIMH 2: Timmy to the Rescue. He is a rude, unenthusiastic, male mouse. He was voiced by Wil Wheaton in the first film, Phillip Van Dyke as an adolescent in the sequel, Eric Idle as his evil self, again in the sequel, and Phillip Glasser as a reformed adult, again in the sequel.
Martin Brisby is 10 years old (by human age) and is the eldest child of the Brisby family. He is rude and smart-mouthed. A running gag is when he has a toxic rivalry with Auntie Shrew, because he hates it when she comes over to babysit and argues with her. But he does care for his family, especially when Mrs. Brisby scolds him for being mean to Auntie Shrew, he feels bad for what he did and apologizes. He may somewhat have some similar traits to his father such as personality as well as physical appearance.
Role in Film
Martin is the second child of the Brisby family who dislikes having Auntie Shrew over their house and is not afraid to yell back at her. He claims that he's not afraid of the dark, the farmer, Dragon (the cat), and the Great Owl.
- Martin has grey fur, the same fur colour as Jenner.
- He is similar to Skippy in Robin Hood.
- In The Secret of NIHM 2: Timmy to the Rescue, Martin is possibly living proof that the chemicals injected into test rats at NIHM, have a small percent chance of driving the subjects insane with increased tendencies of unprovoked aggression and the driven need to dominant others.
- If this theory is correct, then Jenner would have been the first rodent species to suffer from this side-effect.
