Along with Guerrero, Saturn, and Malenko, Benoit debuted in the WWF as a stable that became known as The Radicalz. After losing their "tryout matches" upon entry, The Radicalz aligned themselves with WWF Champion Triple H and became a heel faction. Benoit quickly won his first title in the WWF just over a month later at WrestleMania 2000, pinning Chris Jericho in a triple threat match to win Kurt Angle's Intercontinental Championship. It was also in this time period that Benoit wrestled in his first WWF pay-per-view main events, challenging The Rock for the WWF Championship at Fully Loaded in July and as part of a fatal four way title match at Unforgiven in September. On both occasions Benoit appeared to have won the title, only to have the decision reversed by then-WWF commissioner Mick Foley due to cheating on Benoit's part. Benoit simultaneously entered into a long-running feud with Jericho for the Intercontinental title, with the two meeting at Backlash, Judgment Day and SummerSlam; Benoit winning all three matches. The feud finally culminated in Jericho defeating Benoit in a ladder match at the Royal Rumble in January 2001. Benoit won the Intercontinental title three times between April 2000 and January 2001.
