Ayanami Rei (tentative name), often referred to as "Rei Q," appears in the third and fourth Rebuild of Evangelion movies. While similar in appearance to Rei Ayanami from the previous movies, this is in fact a different character—a clone. The character is as such, very different from both the character in the Rebuild of Evangelion films, and the original story which she is adapted from. (Source: Evangelion Wiki, edited)
