As the star of the film, we had to make sure that if Zero broke his internal armature mid-shot, there was an identical puppet ready to step in.
That means it had to have identical crisscrossing threads, matching knots and the same mottled colour body wrap.
There was one moment when the stunt double broke as well, and I was forced to wrap another Zero midshot while production halted.
In the end, I wrapped a total of six Zero puppets. All as identical as possible.
