Mr. Ages is the tetartagonist of Don Bluth's Secret of NIMH. He is a grumpy loner chemist who doesn't like visitors and he is shown with a light blue cast on his leg. He is voiced by Arthur Malet, who reprised his role in the sequel. It is revealed in the sequence where Nicodemus shows Mrs. Brisby the past that he was with Jonathan in the laboratory.

He was voiced by the late Arthur Mallet.
