Megan moved to San Fransokyo with her father, Diego Cruz. Though they share a loving relationship, Cruz is shown to be extremely overprotective of his daughter. One time, due to being seven minutes late on her commute home, her father sent out his entire police force to find her.
At fourteen, Megan is currently a high school student, with some electives including foreign language and photography. She has a particular interest in journalism, and by extension, mystery solving.
Role in the series
Megan first appears in "Something's Fishy", where Aunt Cass sets her up on a date with Hiro Hamada. Though their meeting had an awkward start, they find that they share things in common, such as an appreciation for robotics and slightly overbearing parents. They decide to hang out again, though this time at Joe's Diner, where Hiro gets to learn more about Megan. In turn, Megan learns that Hiro has little free time outside of school and his internship (as well as being a superhero, though this is kept secret). Megan, believing Hiro is overworked, suggests that they see a movie together, but Hiro's obligations prevent him from going. Later on, Megan and Hiro get together for a study session, in during which, she asks Hiro to accompany her to a school dance. At the dance, a battle breaks between Big Hero 6 and High Voltage. Megan manages to escape with the rest of the crowd, but Hiro stays behind to fight with his team. In the aftermath, Megan and Hiro regroup and are joined by Chief Cruz, who voices his distaste for superheroes and their meddling of legal affairs.
