Origin
Tuppence Terror is the fraternal twin sister of Tommy Terror; she is three minutes younger than her brother. She currently lives in Central City, and was presumably raised there, though she and her brother speak with a heavy Southern accent that may suggest they originated elsewhere in the state or the country.
Creation
Tuppence Terror was created by Greg Weisman, Kevin Hopps and Mike Norton. She was created to tie into the Young Justice animated show.

In Other Media
Young Justice
Tuppence appears in the Young Justice episode “Terrors”. In the episode, she and her brother are defeated fairly early in the episode by Superman and Martian Manhunter following a three-state rampage that culminates in New Orleans’ French Quarter. Tuppence is impersonated by Miss Martian, who uses Tuppence’s image to infiltrate Belle Reve. She later joins up with the Light. Her character design was redesigned for the show proper; in the show, unlike in the comic, Tuppence has long hair that she wears in a ponytail. Also, her eyes, which are green in the comic, are blue on the show. She does not speak in her appearance. She is voiced by Danica McKellar
