Tifa Lockhart (Japanese: ティファ・ロックハート Tifa Rokkuhāto) is a fictional character in Square's (now Square Enix) role-playing video game Final Fantasy VII. Created and designed by Tetsuya Nomura, she has since appeared in the fighting game Ehrgeiz and made cameo appearances in several other titles, as well as the CGI film sequel to Final Fantasy VII, Advent Children and related games and media in the Compilation of Final Fantasy VII series.
A member of the eco-terrorist group AVALANCHE and owner of the 7th Heaven bar in the slums of Midgar, Tifa is the childhood friend of Cloud Strife, the protagonist of Final Fantasy VII. Convincing him to join the group to keep him close and safe, she later assists him in saving the Planet from the game's villain, Sephiroth. Installments in The Compilation of Final Fantasy VII later expanded upon her character, such as in the film Advent Children, where she attempts to convince Cloud to let go of his self-imposed guilt, and move on with his life after Sephiroth's defeat.
