In the final scene of Season 4, Episode 6 ("Kicks Get Chicks"), Demetri's pep talk with Hawk finally has its intended effect and Hawk arrives to practice at Miyagi-Do, the dojo with which he will compete in the 51st Annual All Valley Karate Tournament. Sadly, Hawk loses Miyagi-Do crucial points in the first division and seems to be struggling. After Kyler torments Hawk on the sideline, Hawk seems more deflated than ever before.
Fortunately, Moon approaches Hawk and offers comfort, saying "Ignore him. He's always been a bully, but that's not who you are." When Hawk responds that he doesn't know who he is, Moon assures him that he has never been defined by his haircut and adds, "I liked you for your energy and your confidence." Though Hawk says he lost his confidence, a sudden kiss from Moon seems to turn things around for him. As he approaches the mat, Hawk declares himself "the man who's going to win this whole f—ing thing." With his newfound confidence, Hawk defeats Kyler with ease.
Hawk later fights Miguel and wins by default after Miguel suffers a brutal injury and opts to forfeit the fight. Eventually, Hawk also defeats Robby in the final division, earning revenge against the man who stole his mohawk. This victory also means that Hawk is declared All Valley Champion, winning a trophy and taking home all of the glory in the process.
