His full appearance hasn't been shown so far. What we have seen is Y´s hand and arm with him wearing white gloves and a white coat.
He is the genius clockmaker that rebuilt the dead planet Earth into the Clockwork Planet and also created the automatons of the Initial Y-Series, which were said to be the maintenance machines for the planet, though RyuZU denies this.

After he completed the clockwork planet, he designed and developed the Initial Y-Series, a series of highly advanced automata who excel at one or more aspects.
