Finally, the MASK Firecracker is up on my Rebrickable store, completing the toy line's entire first wave in LEGO!

This rugged pickup truck converts into an elevated recon truck with ease, featuring powerful forward cannons, rear freeze cannons, and a host of other weapons.
The interior holds one minifigure - usually Hondo MacLean - but the detachable dirt bike gives Firecracker co-pilot Buddy Hawks a way to get around as well. Conversion requires partsforming for the forward cannons, but they store conveniently under the truck mode attached to the rear lift arms, so you don't have to worry about misplacing them.
