Mrs. Frisby and the Rats of NIMH
by Robert C. O'Brien
Character Role Analysis
The good doctor is in the interesting role of being both antagonist and unlikely helper to the rats. He's an antagonist because he kidnaps them and forces them into captivity and medical testing against their will. And he's a helper because he gives the rats their extra abilities and talents. Do you think he qualifies as more antagonistic or more of a helpful figure? Shmoop amongst yourselves.
