In the latest arcs of One Piece, Luffy often showcases a completely new technique to conclude intense battles. This technique is not only unique but also incorporates numerous elements that make it particularly dangerous for those who have to bear its impact.
The Gomu Gomu no Star Gun (also known as Gum-Gum White Star Gun) is Luffy’s latest technique in One Piece. The Straw Hat captain used it to strike a powerful blow against a Marine battleship before the “battery ran out.”
Below are the key details regarding the Gomu Gomu no Star Gun technique of Luffy:
1. Luffy Deploys It in Gear 5 Form
The Gomu Gomu no Star Gun was first utilized by Luffy in Chapter 1094 while he was in Gear 5 form.

2. Activation Method of Gomu Gomu no Star Gun
After expanding his bicep and stretching his arm, Luffy spins rapidly before delivering a powerful punch aimed at the target’s head. Since Luffy can strike Kizaru, a Logia-type user, this attack is certainly enveloped by Haki.

3. Star Impact Effect
One of the most striking aspects of this technique is the star impact effect that occurs after Luffy hits the target. When Luffy’s punch strikes Kizaru, it creates numerous starry effects, causing visual distortions that are quite mesmerizing.

4. The Attack Overwhelms Kizaru
As a strong Logia user, Kizaru is incredibly powerful. Even characters who can use Haki, such as Marco and Sentomaru, often struggle against him. However, with the Gomu Gomu no Star Gun, Luffy is able to strike Kizaru without facing significant difficulty.

After being hit by this technique, Kizaru remarked with a hint of disbelief: “Well, this is quite the unexpected turn of events…” Following this, both Luffy and Kizaru descended to the ground.
