[[folder:Phoebe Thunderman]]
->Actor:Kira Kosarin

* BrainyBrunette
* BreathWeapon: Just like her brother, Phoebe has both Heat and Ice Breath.
* ExtracurricularEnthusiast: Phoebe loves going to school and participating in the big math competition. She even refers it as her lair (in comparison to Max's actual lair).
* HarmlessFreezing: Both she and her brother can use their Ice Breath for this.
* HeroProtagonist
* IJustWantToBeNormal
* MindOverMatter: Her main ability.
* NiceGirl
* NotSoAboveItAll: She's not above antagonizing her brother and flaunting her success over him.
* PolarOppositeTwins: The only trait Phoebe and Max share are their powers.
* RedOniBlueOni: The Blue to Max's Red

[[folder:Max Thunderman]]
->Actor:Jack Griffo

* AloofBigBrother: To Billy and Nora.
* {{Badass}}: If single headedly taking on The Grey Ghoul (one of the most powerful and dangerous ghosts, who only his father had ever beaten) [[spoiler: while the ghoul also was possessing Phoebe and thus had access to all her powers (and as they have the same powers that means Max didn't have a hope of being close to equal)]] and not only surviving but bouncing back from the defeat doesn't qualify him, not much will.
* BlackSheep: Max is a supervillain in a family of superheroes.
* ButtMonkey: Not always, but of the cast he does get hurt the most.
* BreathWeapon: Just like his sister, Max has both Heat and Ice Breath.
* BrilliantButLazy: Max is every bit as smart as his sister (academically) but prefers to slack off in class, and work on his inventions rather than study.
* ChickMagnet: A lot of girls find him attractive, including Phoebe's best friend.
* CrazyPrepared
* DanceBattler: When fighting the Grey Ghoul, Max proves he's incredibly agile and quick.
* {{Deuteragonist}}
* {{Envy}}: The whole reason he wants to be a supervillain is because he doesn't want to be a second best hero to his sister.
* EvilGenius: Well he's certainly a genius, and he wants to be evil.
* EvilTwin: Max is (or at least wants to be) this to Phoebe.
* HarmlessFreezing: Both he and his sister can use their Ice Breath for this.
* IJustWantToBeSpecial
* JerkWithAHeartOfGold: For all his claims being evil and being a supervillain, when it really maters he will always come through for his family.
* MadScientist: Has his own lab, builds rockets and doomsday devices and is a unarguable genius.
* ManipulativeBastard: Very good at getting others to do what he wants.
* MindOverMatter: His main ability.
* ThePrankster: Generally his only display that he's evil.
* PolarOppositeTwins: The only trait Pheobe and Max share are their powers.
* RedOniBlueOni: The Red to Phoebe's Blue
* TheUnfavourite: His parents (and apparently the entire superhero community) clearly prefer Phoebe. It's (at least partially) down to this that he wants to be a supervillain in the first place.
* TeenGenius
* TokenEvilTeammate
* VillainProtagonist

[[folder:Hank Thunderman]]
->Actor:Chris Tallman

* BigEater
* BumblingDad: Has shades of this, although he's still savvy enough to know that when you have four kids there is always a good reason to shout. Whether or not his wife is any better though, is [[DependingOnTheWriter debatable]].
* FlyingBrick
* HappilyMarried: To Barb
* LargeHam
* OneHeadTaller: Than his wife.
* OverProtectiveDad: He literally grills anyone who wants to go out with Phoebe.

* SuperStrength: Describes himself as the strongest man in the world.

* HappilyMarried: To Hank.
* LethalChef: To the point her kids try and vandalise her cooking equipment.
* LightEmUp: She can produce and manipulate light as well as electricity and even simulate the effects of sparklers.
* ReluctantRetiree: She is defiantly more willing than her husband, however she still dresses up in her superhero costume and plays a motion capture superhero video game with her husband, while the children are at school. Apparently quite often.
* ShockAndAwe: She wasn't a hero called "Electriss" for nothing.
