Premium Bandai has officially announced the release of the MSZ-006-3B Zeta Gundam 3B Type ("Gray Zeta") in the Master Grade GunPla series!

This highly detailed kit introduces several new features, including a completely redesigned shield equipped with two built-in beam machine guns. It also features a newly molded Large Beam Launcher, an updated Zeta Gundam backpack with flight units, and newly designed armor components. The kit includes a sheet of tetron stickers for enhanced color separation on its armor and a catapult-style display base capable of supporting both Mobile Suit mode and Wave Rider mode.

• Large Beam Launcher
• Shield with dual beam machine guns
• New Zeta Gundam backpack
• Launcher-type display base

The MSZ-006-3B Zeta Gundam 3B Type, also known as "Gray Zeta," is piloted by former Zeon ace Shin Matsunaga, famously known as the "Gray Wolf." Dubbed "Buster" by Matsunaga, this variant of the Zeta Gundam appears in Gundam Evolve Episode 9.

While retaining the iconic silhouette of the standard Zeta Gundam, the Gray Zeta features distinct upgrades. The tail binder splits into two horizontal airfoils behind the head in Mobile Suit mode, while the leg thrusters now feature three small exhausts instead of the usual two.

In terms of weaponry, the new shield provides greater coverage in Wave Rider mode and houses rapid-fire beam machine guns. Unlike the standard Zeta Gundam, the shield no longer serves as the unit's nose in Wave Rider mode. Instead, a detachable Large Beam Launcher takes its place, doubling as a hand-carried weapon in Mobile Suit mode.

The Gray Zeta is equipped with the same beam-deflection coating as the MSN-00100 Hyaku Shiki, giving it a yellow hue—a feature disliked by Matsunaga, who preferred a gray color scheme. It also incorporates a split-panel cockpit screen reminiscent of older mobile suits like the Zaku, rather than the modern panoramic monitors commonly used.
