Mary Frances Gibbons is the mother of Portia Gibbons and a recurring antagonist in The Mighty B! She is also mean to Bessie in any way.
- Bee Afraid-Refuses to give Bessie a badge unless she listens to Penny's story.
- Body Rockers-Yelled at Bessie at the museum.
- Bat Mitzvah Crashers-Won't cut Bessie some slack for missing a honey bee meeting.
- Bad To The Bee and Give Bessie A Bee-Meritted for accidently dropping the Honeybee Taffy.
- Seems to have a crush on Anton St. Germain.
