This is absolutely everything the Core Gundam comes with. A pair of beam sabers with different beam lengths, spray gun, shield, and the PLANETS System itself.
The short beam saber combined with Core's own height actually makes sense. Even if the short beam looks more like a knife, in this smol boi's hands it's already a normal beam saber.
How the Core looks with the long beam saber
The Core Spray Gun is pretty simple, just two parts sandwiched together. But man, that spray gun feels like a beam rifle already given how small Core Gundam is.
