The 1/144 HGAC XXXG-01H2 Gundam Heavyarms Custom (JAN: 4573102688408) is an exciting upcoming High Grade After Colony (HGAC) Gunpla kit from Bandai, bringing the iconic upgraded version of Trowa Barton's mobile suit from Mobile Suit Gundam Wing: Endless Waltz to modern retail shelves. This version features the signature "Custom" enhancements for space combat, including a beefed-up arsenal compared to the base Heavyarms, with a focus on overwhelming firepower.

As of January 11, 2026, this kit is a recent or imminent release (with some sources noting availability starting late 2025 into early 2026, and pre-orders/shipping around October 2025–January 2026). It marks Bandai's move to bring previously Premium Bandai-exclusive Wing suits to wider international distribution, perfect for completing your Operation Meteor or Endless Waltz collection alongside the new RG Wing Gundam Zero!

The Heavyarms Custom is all about saturation bombardment—armed to the teeth for suppression fire and close-quarters chaos. It upgrades the original Heavyarms with space-optimized parts (like an enhanced backpack), while retaining the classic overloaded missile look.

Key features and accessories include:

• Double Beam Gatling Gun (dual-barrel version, mountable on arms or backpack)
• Massive chest-mounted Gatling array and shoulder missile pods (with opening hatches)
• Leg missile compartments (swappable open/closed parts)
• Combat knife (stored on the arm)
• Interchangeable hands and face parts (including the signature half-clown mask)
• Detailed color separation for that straight-from-the-box pop, plus foil stickers for accents

This snap-fit kit uses pre-colored parts (no glue needed), offers solid articulation for its heavy loadout, and is beginner-friendly while rewarding detail work like panel lining or weathering to emphasize the battle-scarred aesthetic. It's a fan-favorite for its "more is more" design philosophy—perfect if you love artillery-heavy suits!
