“71785 Jay’s Titan Mech’s sword is a substantial build using fresh brick designs and it is held in the mech’s hands using a single Technic pin. The options for posing in this mech appear to be abundant too with elbow and knee joints within a unique and lanky build. The sword... More isn’t the only source of new bricks in 71785 Jay’s Titan Mech as the Bone King, Bone Knight and Bone Hunter use new skeletal weapons and minifigure accessories.”

“This is the first large Ninjago mech I've built, and I'm not disappointed. The size surprised me a bit. The limbs are sleek, making it look a lot smaller in photos, but next to a minifig you can see the true size better. The mech has a lot of joints, with moving hips, knees,... More feet, shoulders, elbows and hands”
