The verdict

I like this kit more than its stats suggest I should.

The GP04G never got its own episode, it was scrapped in-universe and repurposed into the Gerbera Tetra, so this RE/100 is basically the only real shot at building the suit as originally designed, and it nails the silhouette. It is not going to out-articulate an MG, and I would not buy it expecting one. What it gives you instead is a clean, dense, oddly satisfying midweight build with a genuinely huge loadout.

Best for: 0083 completionists and GP-series collectors who want the never-deployed GP04G on the shelf next to their GP01 and GP02

The full review

What it is

This is Bandai's RE/100 take on a mobile suit that technically never left the drawing board in the show, the fourth Gundam Development Project unit that got cancelled and reworked into the Gerbera Tetra before Cima Garahau ever piloted it. Building it, that backstory actually shows up in the design. It reads as a clear midpoint between GP01 and GP02, chunkier shoulders, a big fixed shield, and a long beam rifle with an attached beam saber that gives it real presence once assembled. Panel lines are dense enough that from a normal viewing distance it genuinely reads like a much pricier kit, which is exactly what the RE/100 line is built to do.

The catch

The frame underneath all that surface detail is simple. RE/100 deliberately skips the full inner-frame engineering of an MG to hit a lower price point, so the joints are more HG-style than MG-style, and several reviewers flagged the articulation as a genuine weak point, workable for basic poses but not dynamic. It also leans on stickers more than I like for a 1/100 kit at this price, especially for the small greebled accent colors, so plan on a panel-lining pass if you want it to pop the way the box art does. Nothing about the fit is bad, it is just simpler than the price tag might suggest at first glance.

Who it's for

If you are chasing the GP-series lineup or you just have a soft spot for 0083 side stories, this is worth owning, it is the only way to get the GP04G in this scale and it looks the part once built. If your priority is pose range and a full inner frame you feel moving under the armor, put your money into an MG instead and treat this as a display piece rather than a poser. I would also point first-time RE/100 builders toward panel lining, it is what turns this from a good-looking kit into a great-looking one.

The build story

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

Assembly is closer to an HG in feel than an MG, more parts than a standard 1/144 kit for the sake of a nicer finished joint line, but the runners and gates are straightforward and cleanup is not a chore. Fit is generally snug and confident, nothing loose or worrying, and the sheer amount of surface molding means you get a lot of visual reward for a moderate amount of assembly time.

The real standout is the loadout. You get the signature long beam rifle with an integrated beam saber blade, a modified GP01-style secondary rifle, a pair of separate beam sabers, strut boosters, and a shield large enough to actually read as a shield rather than a token accessory. For a kit sitting between HG and MG in complexity, the sheer volume of gear included makes the price feel fair even before you account for how rare this specific mobile suit is in kit form.

Lore & trivia

01The GP04G was the intended fourth unit of the Anaheim Electronics Gundam Development Project, designed with input from former Zeonic engineers to replicate the high-speed assault tactics of the MS-18E Kampfer.
02The Earth Federation never approved the GP04G for completion, and Anaheim reworked the frame into the AGX-04 Gerbera Tetra, which is why the suit never appears fully formed in the Stardust Memory anime itself.
03The completed Gerbera Tetra ended up in the hands of Delaz Fleet officer Cima Garahau during Operation Stardust and was destroyed by Kou Uraki's RX-78GP03 Dendrobium, closing out the suit's only real on-screen combat run under a different name.
04Bandai released this kit in April 2015 as entry number 003 in the RE/100 line, a lineup built specifically to cover mobile suits too niche or too large for a full Master Grade release.
