Mim is presented as boisterous, mischievous, and rather conceited, a sorceress much impressed with her own power who delights in causing trouble. She is also a somewhat morbid character with a distaste for sunshine and all things wholesome. When Arthur is transformed into a sparrow by Merlin, Mim discovers him and initially tries to impress him with her magic, boasting that it is more powerful than Merlin's. Upon further realizing his relationship with Merlin, she then attempts to torture him eventually decides to try and destroy him, being that she sees all good things as bad.

Merlin arrives to rescue Arthur, but Mim refuses to give him up and challenges Merlin to do otherwise. This leads to a "Wizards' Duel" between her and Merlin for Arthur's life, in which both parties transform into a series of animals to destroy one another. The animals Mim turns into were an alligator, fox, chicken, elephant, tiger, rattlesnake, rhinoceros, and finally a dragon. And the animals Merlin turns into were a turtle, rabbit, caterpillar, walrus, mouse, crab, billy goat, and finally a mouse again. She appears to win the duel by cheating, but Merlin quickly turns the tables by turning into a germ and goes inside her, rendering Mim ill and powerless.
