Martin Brisby is the eldest son (and second-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, Eric Idle as his evil self in the sequel, and Phillip Glasser as a reformed adult also in the sequel.


Martin Brisby is 10 years old (by human age) and is the eldest son 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 filmEdit

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), or the Great Owl.
