Spinner, if you don't recall, was a Toa of Air who was left injured in a deep pit by his team, and joined the Dark Hunters. Due to how heavily injured he was, he is almost completely rebuilt. He does not currently wear a mask, which indicates he no longer needs one.
Now obviously, he doesn't wear a mask because the fan-model didn't have a mask, but can he still wear one? Can he still use one?
