70725 Nindroid MechDragon is a Ninjago set that was released in 2014. It contains 691 pieces. It was released in December 2013 in the US and Canada.


MechDragon was created by Overlord to capture Lloyd Garmadon. In its first attempt, Lloyd and Garmadon tried to escape it using Nya's car. Lloyd shooted rockets at him, but it crashed after ninjas shut off the power in power station. Later it was powered with Electro Cobrai. There Tech Wu captured Garmadon and throwed him to the sea. After Pythor caught Lloyd, Overlord drained his golden powers in the capsule. When ninjas destroyed Overlord virus in the Digiverse, MechDragon lost Overlord's control and got destroyed in the sea. Nindroids found them and Overlord in his physical form alive there, and lifted the dragon with air balloons.
