Mrs. Rocket could refer to any of three people, only two of whom were developed as characters:
- Raymundo's mom, who is also Reggie and Otto's paternal grandmother, whom we have never seen and whose name we do not know
- The late Danielle Rocket, Raymundo's first wife and Reggie and Otto's birth mother
- The former Miss Noelani Makani, Raymundo's second wife and Reggie and Otto's stepmother
Fanfiction frequently has Otto marrying Trish, Clio, or some original fancharacter in his adulthood. This would also create another Mrs. Rocket.
