He quickly proved he was more than just a grappler by using striking skills. He earned knockout victories over fighters like Din Thomas and Caol Uno. One of his most famous moments occurred in 2004 at UFC 46. He moved up in weight to challenge the Welterweight Champion, Matt Hughes. Despite being the underdog, Penn won using a rear naked choke. This move involved controlling the opponent's back and applying pressure to the neck. This victory remains one of the greatest upsets in mixed martial arts history.

During a period away from the UFC, he signed with the Japanese promotion FEG. While fighting for FEG, he won a middleweight bout against Rodrigo Gracie by decision. He also defeated Duane Ludwig using an arm triangle choke, which is a submission using the arms to compress the neck. However, the UFC stripped him of his welterweight title during this time.
