Ms. Keane is the girls’ teacher at Pokey Oaks Kindergarten in The Powerpuff Girls.
The school scenes show Blossom, Bubbles, and Buttercup trying to balance ordinary kindergarten life with their responsibilities as superheroes. Ms. Keane represents the everyday adult authority figure in that setting.
Pokey Oaks Kindergarten is separate from Townsville City Hall, where the Mayor and Sara Bellum work. That distinction matters because both locations contain recurring adult characters, and their roles are sometimes mixed up by viewers.
Ms. Keane appears in stories involving classroom rules, school friendships, and the girls’ attempts to keep their powers and heroic identities from disrupting ordinary lessons. Her character helps contrast the trio’s extraordinary lives with familiar childhood routines.
