Get a clear look at the Diaclone DA-98 Grand Dion Reinforcement Unit A — what it includes, how it attaches, and what it adds to your Grand Dion setup.
Quick answer
The Diaclone DA-98 Grand Dion Reinforcement Unit A adds a second main turret, a sub turret, and a machine gun to your Grand Dion, plus a Diaclone member Ver. 2.0 figure, letting you expand the battleship functions and transform the combined unit into a bipedal heavy machine mode.
What the Reinforcement Unit A includes
The set contains a second main turret that mounts on the flight deck, a sub turret that fits into the storage lift, and a machine gun that can connect to any joint. It also includes one Diaclone member Ver. 2.0 figure.
Compatibility considerations
This unit is designed specifically for the Grand Dion base figure. It does not include the Grand Dion itself, so you need the original set to use these parts. The turrets and sub turret attach using existing connection points, but the instructions are in Japanese only.
How to install and use the Reinforcement Unit A
- Attach the second main turret to the flight deck: Locate the connection point on the top of the Grand Dion flight deck. Align the second main turret’s peg with the slot and press firmly until it clicks. The turret should sit flush and rotate freely. Do not force the peg — if it doesn't click, check alignment. Forcing may damage the connection.
- Mount the sub turret in the storage lift: Open the storage lift compartment on the Grand Dion. Insert the sub turret base into the lift slot until it locks. The sub turret can be raised or lowered with the lift mechanism. Ensure the lift is fully open before inserting the sub turret. Inserting it partially can jam the mechanism.
- Connect the machine gun to a joint: The machine gun comes with a universal peg. Attach it to any 5mm joint on the Grand Dion or the turrets. Common positions include the side of the flight deck or the rear of the sub turret. The machine gun peg fits standard Diaclone joints but may be loose on some third-party figures. Test fit before displaying.
- Transform to bipedal heavy machine mode: Keep all units connected. Follow the transformation sequence in the Japanese instructions: fold the flight deck forward, rotate the turrets, and extend the legs. The combined unit becomes a bipedal heavy machine. The Japanese instructions use diagrams. If you get stuck, search online for fan translations or video guides. Do not force any joint — the transformation should move smoothly.
Product details
- Diaclone DA-98 Grand Dion Reinforcement Unit A (Second Main Turret & Sub Turret Set): From Takara Tomy comes another unit to strengthen the battleship-like functions of the mighty Grand Dion Diaclone unit. You can connect the second main turret on the flight deck and the sub turret in the storage lift. A machine gun that can be connected to each joint is included. Each unit remains connected and transforms in bipedal heavy machine mode. This means you can add firepower and modularity without permanently modifying the base figure, and the combined mode gives you a new display option.
