The verdict

This is the RG Strike frame at its most dressed up, and I think it earns the extra hardware.

The Build Booster gives it real shelf presence beyond the plain Strike, the color separation on the armor is genuinely impressive for 1/144, and the accessory loadout (two beam sabers, a Chobham shield, a beam rifle that assembles from two guns) makes it feel like a complete package, pun intended. It is not the most stable RG in the line, and I noticed that the moment I started swapping poses.

Best for: RG collectors and Build Fighters fans who want the Strike frame with real accessories and don't mind reaching for a stand

The full review

What it is

This is the RG Strike Gundam frame with the Build Booster docked on its back, and it reads as a genuinely different kit on the shelf rather than just an accessory pack. The molded color separation on the armor is where RG earns its reputation, the white, red, and blue panels come out of the runners looking right with barely any painting needed. Snapping the booster onto the backpack and locking in the beam rifle for the first time is a satisfying moment, it visually transforms the kit from a slim Strike into something with real bulk and presence. Four head vulcans, twin beam sabers, and the Chobham shield round it out nicely.

The catch

The RG Strike frame under all this is an older RG mold, and it shows. Builders consistently flag that the ankles and hips get loose once you start posing with the extra weight of the Build Booster on the back, and the kit tips over easily without an action base, which isn't included. The backpack attachment point takes the brunt of that weight and some builders report it doesn't hold as firmly as they'd like during dynamic poses. Small polycap and frame parts are the usual RG fragility risk if you're rough with nub removal. None of this is a dealbreaker, but budget for a stand.

Who it's for

I'd point this at builders who already like the RG Strike lineage or who came to it through Gundam Build Fighters and want Sei and Reiji's actual kit, not just the base Strike. It rewards patience during assembly and pays it back with a genuinely detailed, well-armed model that looks the part standing still. If your priority is rock-solid posing and you want to really rack it through dynamic action shots, I'd steer you toward a newer RG mold or up to an MG Full Package instead, this kit is happier held than thrown into deep lunges. First-time RG builders should also know this isn't the gentlest entry point given the small parts.

The build story

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

Assembly follows the familiar RG Strike sequence, inner frame first, then the armor shells clip over it panel by panel. Gate placement is typical Bandai RG, mostly on flat or hidden surfaces, though a few of the smaller Build Booster parts have nubs in visible spots so I'd take a hobby knife slow there. Nothing about the build itself is frustrating, it's more time-consuming than fiddly, and the payoff of watching the booster and rifle come together at the end makes the extra runners worth it.

Articulation-wise you get the RG Strike's double-jointed elbows and knees, a ball-jointed neck, a waist that spins the full 360, and skirt armor that swings out of the way of the legs, so the range on paper is solid. The catch is holding that range once the Build Booster's extra mass is riding on the back, which is where the looseness complaints come from. Part count and accessory value are strong for the price point, you're getting a shield, two sabers, a modular rifle, and the booster itself, which is a lot of kit for a 1/144 RG.

Lore & trivia

01The Build Strike Gundam is Sei Iori and Reiji's first Gunpla in Gundam Build Fighters, built on the GAT-X105 Strike Gundam frame from Mobile Suit Gundam SEED.
02Docking with the Build Booster is what turns the base Build Strike into the 'Full Package' configuration, adding two Variable Speed Beam Rifles and a jump in output.
03The kit's armor is molded to represent Chobham composite armor plating, the same real-world armor type used on modern main battle tanks, referenced directly in the in-universe design.
04This RG release (RG #23) came out in December 2016, several years after the anime aired, giving the Strike frame a proper Real Grade treatment of its Build Fighters incarnation.
