Chrono Cross
A few of the core characters from "Chrono Cross" originate from an earlier game titled "Radical Dreamers". "Chrono" series writer Masato Kato felt that the first game in the series, "Chrono Trigger", did not wrap up all its story arcs, and as such, wrote the story of "Radical Dreamers" to conclude some aspects of it. However, due to the rushed nature of the development schedule, it being a short, text based visual novel, and being released on an obscure add-on for the Super Famicom, the Satellaview, Kato would label the game "unfinished", leading to the conception of a more complete game, which would be "Chrono Cross". Serge, Kid, Lynx, Viper, Radius, and Riddel all originate from the game. Additionally, the "Radical Dreamers" character Magil, who is an amnesiac Magus from "Chrono Trigger", was originally going to be the character Guile in "Chrono Cross", before Kato wrote him out of the script, fearing he could not do the character justice in the massive scope of "Chrono Cross". While "Radical Dreamers" characters were used as a base for the characters of "Chrono Cross", Kato made changes as well. In "Radical Dreamers", Serge acted as the game's narrator, rather than a silent protagonist, and Lynx, is just a regular human, rather than an anthropomorphic cat. With the release of "Chrono Cross", the characters and events of "Radical Dreamers" were retconned as being from a similar but different alternate reality.
