Kamen Rider Knuckle or known as Zack is a former member of Azami's Beat Rider team and the former second leader of Team Baron. As the group's former second-in-command, he was promoted to the position when their leader, Kaito Kumon, stepped down to focus on the mystery surrounding Helheim Forest. In his first Inves Battle, he is shown using the Matsubokkuri Lockseed. He later receives a mass production Sengoku Driver from Kaito who obtained it during his capture and escape from Yggdrasill. When Kaito quits Team Baron so that he can fight the Yggdrasill Corporation and not to put his teammates in danger, he gives Zack the Team's leadership and gives him a Sengoku Driver.
When Oren is about to disrupt the Beat Riders' stage performance, Zack shows his heroic side for the first time in the series by risking himself to protect the Beat Rider dancers via becoming Kamen Rider Knuckle and assisting Gaim. With the Sengoku Driver he received and his own Kurumi Lockseed, he is able to transform into Kamen Rider Knuckle, the second rider in Team Baron. Like with the other Armored Riders, Kamen Rider Knuckle's forms are called Arms. His Sengoku Driver plays American rock & roll music and emits a guitar riff sound before every transformation, while his personal Lockseeds are styled in pure English with a Mr. Adjective/Noun theme. By pressing the Sengoku Driver's Cutting Blade down on the Lockseed after transforming from one to three times, Knuckle can activate one of three finishing moves based on his current Arms form: Squash, Au Lait, or Sparking.

Knuckle Ride Wear
- Knuckle Ride Wear
- The Ride Wear is Knuckle's default form undersuit, which is briefly seen during Knuckle's transformation sequence before the Armor Part attaches or when he changes Arms. However, this form is completely vulnerable to any incoming attacks when shot at directly in the suit rather than at the Arms that is descending down on the Rider.
- Unlike the original Armored Riders, Knuckle's Ride Wear isn't identifiable through his Sengoku Driver's Rider Indicator faceplate due to using a mass-produced Sengoku Driver.
