Lucca Ashtear

Lucca Ashtear (Japanese: ルッカ・アシュティア, Hepburn: Rukka Ashutia) is a fictional character in the Chrono series of video games designed by Akira Toriyama. Her design did not change much during development, with the only major difference being a change in headgear. She is one of the main characters of the 1995 game Chrono Trigger by Square where she is known as a brilliant inventor in the canon of the series. She is the best friend of the protagonist Crono and is instrumental in advancing the story multiple times. She also appears in Chrono Cross as the caretaker to one of its protagonists, Kid.

She has received praise for being a positive example of a female scientist in video games, with one critic suggesting that she is a positive influence for aspiring female scientists and engineers. She has also been discussed as a character defying gender stereotypes, due to her style of clothing and high level of intelligence. A scene where her mother loses the use of her legs and Lucca has the opportunity to use time travel to prevent this has been the subject of positive reception, both for the possibility of failure and in how it impacts Lucca emotionally, regardless of success.
