What is the name of the main antagonist in Forza Horizon 1?

The main antagonist in Forza Horizon 1 is Darius Flynt. He is the reigning champion of the Horizon Festival and the final major rival the player must defeat to become the festival's top driver.

Darius is presented as an arrogant, dangerous competitor whose reputation dominates the festival. The player progresses through Colorado by winning events, earning popularity, and challenging increasingly prestigious racers before finally facing him in the concluding showdown.

Darius is sometimes confused with characters from later Forza Horizon games, especially because the series reuses festival terminology and recurring racing personalities. Ramiro, for example, is associated with Forza Horizon 4 rather than the original game's central conflict. Darius Flynt is specifically tied to the first Forza Horizon's story and final rivalry.
