Miss Almira Gulch is a strict neighbor of Aunt Em, Uncle Henry, and Dorothy Gale in the 1939 film The Wizard of Oz. As the Wicked Witch's Kansas counterpart, she was portrayed by the late Margaret Hamilton, who also portrayed the Wicked Witch of the West.
Dorothy Gale and her dog, Toto, run to their farm in Kansas after an encounter with Miss Gulch, who hit Toto on the back with a rake. No one at the farm seems interested in this, however. Finally, Miss Gulch arrives and announces that she will have Toto destroyed because Toto bit her on one of her legs and got the sheriff to give her an order for it. She takes Toto away in a basket on her bike, but Toto escapes and runs back to Dorothy. Realizing Miss Gulch will return for him, Dorothy and Toto decide to run away. Unfortunately, she did not arrive as the tornado struck the farm.
Dorothy saw Miss Gulch riding on her bicycle inside the tornado, but Miss Gulch suddenly transformed into a Wicked Witch. Her bicycle becomes a broom at that same moment.
It is unknown if Miss Gulch is killed during the storm while bicycling back to her home, or the Gales will be paid another visit by her looking to take Toto away again. However, in most professional play productions, the script used often has Uncle Henry mention to Dorothy when she wakes up that, "A telephone pole fell on her". While that was her fate in the theatrical adaptations, it can be implied to be the same in the film, but if she survived, it's possible also that upon seeing all what Dorothy went through, she just opted to not bother the Gales again.
