Thea Stilton is the main protagonist in the Thea Stilton series. She is Geronimo Stilton's older sister and a special correspondent for The Rodent's Gazette.


At Mouseford Academy

One of her favorite adventures begins at Mouseford Academy, the school she went to when she was just a young mouseling. When she came back to teach a journalism class when her friend (principal of the school when she was a young mouselet) Octavious de Mousus invited her. (when she was a grown mouse) she met five special mouselets. They liked her so much that they decided to name their group the Thea Sisters after her. Thea was so touched by that, so she decided to write about the famouse adventures of those five mice.

Appearance and Personality


Thea is a tall, slender and a gray furred rodent. She has a long snout. Her outfit often changes but in the books she is often seen wearing a royal blue jacket with a white fur collar, a lavender or pink scarf and blue pants.

In the TV series, her appearance is still the same as the book series; tall, slender, and grey-furred. Her clothing has varied from the book series, however. She wears a black jacket with white collars and a pair of yellow buttons on their tips, underneath it is a pink v-neck shirt with its collar folded slightly upwards to the outside, and a pair of dark grey pants on the bottom. She has a reddish-orange nose (color depends on lighting), a pair of purple irises in her eyes and has purple eyeshadow applied on the eyelids.


She is shown to be very athletic and loves all sports, especially Karate, Kung Fu, and Rat-jitsu. She usually gets into fights with Trap. She drives a motorcycle, and gets a kick out of bursting into her brother's office at the Rodent's Gazette while riding it. oh, and she loves adventures too.

Thea is shown to be quite the opposite to her brother as she absolutely adores travelling, going on adventures and meeting rodents from all around the world; while Geronimo hates planes and is afraid of almost everything. Like Trap Stilton, she sometimes calls Geronimo 'fraidy mouse." She loves the colour pink. She flew in a pink helicopter full of pink wedding items for Miss Angel Paws and Gentlemouse's wedding.

Thea has a very alluring effect on male mice, and many like her. Hercule Poirat and Bruce Hyena both have a crush on Thea.

  • In the TV series, she is voiced by Sarah Edmondson.

  • In both the TV and book series, Thea has the license to pilot just any vehicle. In the books, she's driven her motorcycle, sailed a catamaran to Whale Island and she's even mentioned to drive a car. In the cartoon, she pilots a helicopter, a plane, her motorcycle, Geronimo's car, and pilot the Metamouse Multi-vehicle.
  • In the TV series, Thea's motorbike is depicted as a pink superbike resembling a Ducati while in the books, it is depicted as an 80's naked bike with a cheese-colored paintjob.
  • In the later books in the Editorial Staff photo, Thea can be seen parking her motorcycle on the round table inside Geronimo's office while there are still mice using it.
  • With the status of Geronimo actually being adopted to the Stilton family, it is unknown for sure if Geronimo is her biological brother.

Description according to Atlantyca

"Thea is a special correspondent for the Stilton Media Group. She isn’t much of an office mouse, she prefers hanging from tree branches and climb building ledges to get the perfect shot. Thea is strong and confident. She has a black-belt in Karate and she can pilot or drive anything that’s been built, but she’s also vulnerable and has a wry sense of humor. There’s a sensitive side to Thea, her weak spot being for Benjamin, whom she loves dearly and would do anything for. Thea is a tomboy and adventurer. Her insecurities however are with her feminine side. That’s another area where’s she’s vulnerable. She’s beautiful, and loves to look pretty, but she’s out of her element in a ball gown and high-heels. She can carry it off… until she has to walk, then her awkwardness shines through."
