|“||This is me, Eliza Thornberry, part of your average family. I got a dad, a mom, and a sister. There is Donnie, we found him. And Darwin, he found us. Oh yeah, about our house, it moves, cause we travel all over the world. You see, my dad hosts this nature show, and my mom shoots it. Okay, so we're not that average. And between you and me, something amazing happened… and now I can talk to animals. It's really cool, but totally secret. And you know what? Life's never been the same.||„|
|~ Opening narration|
Elizabeth "Eliza" Thornberry (born September 30, 1987) is the main protagonist of The Wild Thornberrys and The Wild Thornberrys Movie, and a supporting character in Rugrats Go Wild.
She is a 12 year old girl, who (unknown to most except to her big sister Debbie) gained the ability to speak with animals after an encounter with an African shaman (as shown in the episode "Gift of Gab"). If she tells anyone that she can talk to animals, she'll lose her powers.
Despite her best intentions, sometimes Eliza's stubbornness that she's always right leads her strong desire to help to become destructive. Eliza is portrayed as a geek by her extensive zoological knowledge and her glasses, braces and by occasionally standing pigeon-toed. She and Darwin get into arguments when the situation gets bad..
She was voiced by Lacey Chabert, who also portrayed Gretchen Wieners in Mean Girls and voices Aleu in Balto 2: Wolf Quest, Tanya Mousekewitz in An American Tail: The Treasure of Manhattan Island, Meg Griffin in Family Guy Season 1 and younger Vitani in The Lion King 2: Simba's Pride, and voiced both younger and older Vitani in The Lion Guard.
She has freckles and long red-orange hair that is usually worn in pigtails and occasionally a ponytail. She almost always wears a yellow dress, though later in the series she sports other clothes. Eliza is 11 in the series and 12 in the movie.
- Despite being the main character of The Wild Thornberrys film and series, Eliza plays a supporting role in the film, Rugrats Go Wild.
- She shares her birthday with her voice actress, Lacey Chabert. However, Eliza was born in 1987, and Lacey was born in 1982, 5 years apart.
