Mrs. Brisby
Mrs. Jonathan (Elizabeth) Brisby is the widow of Jonathan Brisby, a mouse who helped a group of intellectually-enhanced rats escape from NIMH (National Institute of Mental Health) and a life of cruel experimentation. Unaware of her husband's heroism, Brisby lived a quiet life raising their children before her youngest son Timothy's illness led her into an encounter with the NIMH colony. Though she still prefers a life away from heroics, the events of Heroes vs Villains forces her back into the frontlines in the war against evil.
