The verdict

I love this kit for what it dares to be, and I have to warn you about what it actually is once it's built.

The Hamma-Hamma is one of the strangest and most ambitious shapes Bandai ever put into the RE/100 line, and building it is genuinely fun in a way most kits aren't. But it lands as a display piece first and a poseable robot a distant second, and you need to walk in knowing that.

Best for: collectors who want a weird, lore-rich Neo Zeon prototype as a shelf centerpiece, not a kit you handle often

The full review

What it is

This is Bandai's take on one of Gundam ZZ's oddest designs, a hulking quasi-psycommu test suit built around detachable wire-guided claw arms instead of conventional hands. At 1/100 the thing is enormous, and the parts breakdown backs that up: two distinct tones of green plus yellow piping, red for the thruster ring and beam cannons, dark grey frame components, and clear parts for the sensors, almost all molded in color rather than painted on. The tiny sticker sheet only has three stickers and I skipped all of them without missing a thing. Clipping this one together and watching that silhouette come up out of the runners is a genuinely good time.

The catch

Here's the part I have to be straight about. This kit is wobbly. The finished model is a big, top-heavy hulk that needs its stand to stay upright, and once it's posed on that stand you will not want to keep touching it. The wire-guided claw arms are the coolest gimmick in the box, but they're floppy by design and don't hold dramatic extended poses without the included display arms doing the actual work. Treat it as a diorama piece you set once, not a toy you re-pose weekly, and the experience clicks into place.

Who it's for

If you're chasing the definitive Universal Century roster and want a Neo Zeon prototype nobody else on your shelf has, or if you just love oddball mecha silhouettes, this is worth the build. Skip it if you want a kit you can pick up and repose casually, or if snap-tight, rock-solid joints matter more to you than novelty. I'd point newer builders toward a more conventional RE/100 first and save the Hamma-Hamma for when you're ready to build for looks over handling.

The build story

What the build is actually like, and the engineering worth knowing about.

The build itself moves fast and stays satisfying, with clean gate placement on most runners and parts that snap together with the confidence you'd expect from the RE/100 line. The color-molded plastic does the heavy lifting here, two greens plus yellow piping plus red thruster accents, so the finished suit looks fully painted straight off the runners with only three optional stickers on the entire sheet.

The standout engineering is the wire-guided claw hand gimmick, a genuine attempt to reproduce the anime's quasi-psycommu long-range attacks in plastic, backed by four included display arm stands that let you pose the suit mid-attack. The giant shield and pair of beam sabers round out a loadout that feels appropriate for the suit's size, though the overall stability of the finished model is the tradeoff for chasing that spectacle.

Lore & trivia

01The Hamma-Hamma was a Neo Zeon prototype built to test the experimental quasi-psycommu system during the First Neo Zeon War depicted in Mobile Suit Gundam ZZ.
02Its quasi-psycommu technology never reached mass production in the Hamma-Hamma itself, but was later refined and carried over into the AMX-014 Doven Wolf.
03The suit is built around detachable, wire-guided claw hands armed with triple-barreled beam guns, capable of extending to strike at range independent of the main body.
04In the show the Hamma-Hamma was able to land a serious hit on AEUG's MSZ-006 Zeta Gundam, destroying its head in combat.
