Main

Phoebe Thunderman (Kira Kosarin) is a twin to Max, though she is 20 seconds older, and older sister to Billy, Nora, and Chloe. Her superhero alias is Thunder Girl. She is very responsible, a straight A student, and tries to play by the no powers rule. She has telekinesis, freeze breath, and heat breath. In "Thundersense", Phoebe develops a new ability called Thundersense, which warns her if she and others are in danger, like being trapped by a villain. Since the beginning of the third season, Phoebe has been training to become a superhero and officially becomes Thunder Girl in "Thundermans: Secret Revealed". However, in "Come What Mayhem", during an attempt to stop one of Max's former pranks from going off, Phoebe accidentally absorbs Dark Mayhem's powers and turns evil until she returns to normal in "Thunder in Paradise". At the beginning of the series, Phoebe is 14 years old.

Max Thunderman (Jack Griffo) is a twin to Phoebe and older brother to Nora, Billy, and Chloe. His powers include telekinesis, freeze breath, and heat breath. He is the antagonist-turned-anti-hero. Despite being raised within a family of superheroes, Max originally aspires to become a supervillain for the first three seasons. His sole reason was to not be second best to Phoebe as a hero. In "Thundermans: Secret Revealed", he finally has a change of heart and makes a life-changing decision to abandon the dark side and become a fighter for justice, using his powers and high-tech gadgets for the greater good. The fourth season focuses on Max re-adjusting to his new daily life as a superhero instead of an evil-doer, as he tackles challenges working with Phoebe in Z-Force training, which jeopardizes his friendship with Dr. Colosso. His basement bedroom serves as his secret lair, filled with high-tech gadgets and posters of the Villain League. In the fourth season, his lair has posters of the Z-Force and other superhero posters. His lair is accessible through a slide leading to his bed underneath a tea table next to the couch in the living room and it is also where he keeps his best friend and mentor, Dr. Colosso, a supervillain Thunder Man turned into a rabbit. At the beginning of the series, Max is also 14 years old.
