LEGO fans young and old alike, I present to you, the DualDock system. It is a fighter drone that can combine with one of two docks to form two different vehicles.
This particular model, the BT-01, can combine with one of its docks to form either a jet or a tank.
Having the two-vehicle docks makes for long-term playability in that you are essentially getting two vehicles in one set that you can switch out on the fly.
