Do the rest of the metru have wearable masks?
No only Nuju and Vakama got wearable masks. Hordika Whenua got a wearable mask along with Vakama though

To be honest, I thought those were actually kinda neat, even if you can't use them for much else.
the technic minifigure's were so neat. They'd be worth at least a reissue for a Technic anniversary line
