The Dark Lord Arrives

Introducing LEGO Star Wars SMART Play: Darth Vader's TIE Fighter™ 75421. With 473 pieces, this build stands 4 in (10.2 cm) high, 5.5 in (14.0 cm) wide, and 4 in (10.2 cm) deep. It brings a new interactive layer to the iconic starfighter, bridging physical play with digital engagement.

All-in-One Experience

Beyond the main TIE, we get a detailed Rebel defense station and essential SMART Play tech. The integrated brick and tag components, along with the charging pad, lay the groundwork for dynamic interactive scenarios. Our Rebel Fleet Trooper and Darth Vader minifigures are ready for action.

Hidden Tech Revealed

The reverse showcases the Smart Brick integration within the TIE Fighter's core, connecting to the charging station. This reveal highlights the sub-assemblies for the TIE and the ground defenses, all reacting to your movements. The interactive QR code hints at expanded play possibilities.

Dynamic Combat Action

Feel the swoop of Darth Vader's TIE as it dives towards the Rebel position, green laser elements streaking forward. The TIE's angular panels and cockpit capture its menacing silhouette, ready to unleash destruction. The Rebel Fleet Trooper on the ground mans his blaster cannon.

Gritty Ground Defenses

This small Rebel outpost is packed with detail, featuring a blaster cannon and a comms dish, all greebled onto tan and dark tan plates. The trans-clear screen element shows a desperate effort to hold back the Empire. The Rebel Fleet Trooper takes aim, ready to defend.

Powering the Dark Side

The Smart Brick, with its integrated sensors and lights, connects directly to our Darth Vader minifigure via a Smart Tag. This setup transmits Vader’s commands and movements into the interactive play system. It's a clever NPU, bringing the minifigure to life.

Motion-Activated Flight

Hold the TIE Fighter and feel the acceleration as the internal Smart Brick reacts to your hand movements, simulating flight. The splayed solar panels and the distinct cockpit sphere are structurally sound, allowing for seamless swooshability. Notice the emerging laser elements from the wingtips.

Docking for Power

The TIE Fighter connects to the charging station, showing the internal mechanisms and the Smart Brick slot. The cable from the station plugs directly into the ship's internal port. This setup keeps Vader's starfighter ready for continuous missions across the galaxy.

Vader Takes Control

The hinged cockpit canopy opens to reveal the detailed interior, allowing Darth Vader to be placed at the controls. The Smart Brick integrates neatly into the central core, maintaining the sleek design while adding interactive functionality. It's all about immersive play.

The Lone Trooper

Here stands our Rebel Fleet Trooper, equipped with his standard blaster rifle and helmet. The minifigure captures the iconic look of the Rebellion's foot soldiers. His printing details are clean and sharp, ready for skirmishes against Imperial forces.

Ready for Galactic Conflict

This top-down view showcases all interactive elements: the Smart Charger, Smart Brick, Smart Tag, and the two minifigures, Darth Vader and the Rebel Fleet Trooper. The TIE Fighter Smart Tag is prominently displayed, tying the whole system together for interactive missions.

Plugging in the Power

Installing the Smart Brick into the TIE Fighter's central hub is a straightforward process, securing it with excellent clutch power. The arrow guides the placement, ensuring the internal electronics connect correctly. This prepares the starfighter for its initial system boot-up.

Interactive Re-Arming

Connecting the TIE Fighter to the charging station not only replenishes power but also initiates interactive prompts, indicated by the fuel and sound icons. This moment is where the digital play aspects are triggered, making the physical model "come alive." It's a clever NPU of interaction.
