SDBD:R 018 Avalanche Rex Buster

The articulation on the Rex Buster mode is tight enough that it holds its pose mid-swing without sagging, and swapping it into the backpack config takes under a minute. Such a slick add-on for the Valkylander, and the saber form slots in with zero wobble.

The transformation from backpack to Rex Buster is surprisingly smooth, and it clicks into place securely. It adds a lot of presence to the Valkylander without being too bulky.
