I watched the Ninjago Dragons Rising mech shorts not too long ago and decided to build this for Nya since she was helping out in one of the episodes.
As you can see, I specifically designed this mech for underwater combat. As such, the unique features of this mech are fins on the lower limbs, propellers on the shoulders, flippers, an air tank on the back, and a water-tight cockpit. In addition, I gave the mech a spear for a weapon to match the spear Nya wields.
Unfortunately, because of these features, I wasn’t able to get the chest logo feature that all the other mechs of this type have. But, I’m quite content with this build.
