Lightning is a fictional character from Square Enix's Final Fantasy series. She first appears as a playable character and main protagonist of the role-playing video game Final Fantasy XIII, featuring as a former sergeant in the Guardian Corps whose sister Serah has been branded as a l'Cie. In her attempt to save Serah, Lightning and others are also branded and tasked with destroying their home by the fal'Cie, a divided race of demigods who rule the worlds of Gran Pulse and Cocoon. She reappears as a supporting character in Final Fantasy XIII-2, residing in the netherworld of Valhalla as protector of the Goddess Etro. She is the sole playable character in Lightning Returns: Final Fantasy XIII, in which she sets out on a quest to save the people of her world, which is destined to end in thirteen days. She is also featured in other games within the series, most notably the crossover game Dissidia 012 Final Fantasy. Lightning was created by Motomu Toriyama, the game's director and scenario writer, and designed by Tetsuya Nomura. The idea was to create a female protagonist new to the series, who was strong, good at fighting, and less feminine than previous heroines within the franchise. Over the course of the games, she went through multiple design changes, many of which were meant to reflect her role and development in each game, particularly in Lightning Returns. Lightning's real name is Claire Farron in English and ��clair Farron in the original Japanese-language version. She took the code name "Lightning" to escape her vulnerabilities and insecurities, and become a stronger person.
