A couple more LEGO Ninjago 2014 set images have come forward from Brixit.
For the Hover Hunter (70720), we get Cole and a Nindroid and a hovercraft-like vehicle that has some saw blades in the front.
On the NinjaCopter (70724), you get four minifigures, Zane, a new character called Pixal, General Cryptor, and a Nindroid. The NinjaCopter is driven by Pixal with Zane in the back. I’m guessing that Pixal is related to Zane and could be his mother.
The Nindroid MechDragon (70725) contains five minifigures: Sensei Garmadon, Evil Wu, Lloyd, and two Nindroids. The MechDragon itself is pretty menacing looking. It’s mostly silver, black, and purple with blade wings and also includes some saws on each of the wings. There is also a small off-road type vehicle that Sensei Garmadon and Lloyd drives. It also includes a brick separator!
