Nora Thunderman is potrayed by Addison Riecke.
Nora is showed to have a mischevious personality, as well as having a habit of arguing with her brothers a lot. She has a calm demour, even though she's young, though sometimes she can still freak out without screaming and yelling at all. She's pretty cool with stuff, as shown in Phoebe vs. Max.
"Hey Phoebe, whatcha doing? Oiling Max's slide? Cool." -Nora
