??? (provisional name) is a large robot seemingly in the service of Faputa, though it is capable of independent thoughts and actions. It is the Interference Unit of the 6th layer, which it referred to as the Bell Tower Layer. It is capable of speech, but usually just makes a "gooon" noise.
An Interference Unit's purpose is to observe and interact to gather knowledge. According to it, there is an Interference Unit for each layer, though the state of the other Units is unknown. There has been no contact between any of the Units for some time, as Interference Units cannot cross layers.
Its upper body is very large, with a jagged beak-like "mouth" attached to its front with an oval-shaped metal frame and some large bolts. From underneath the metal frame is a large cape flowing over its "shoulders" and down its back. On top of it is what looks like an open cart with a hand rail, as if it was made to transport people. It can shoot out of a cannon on its right arm, and its left arm resembles a large pincer. Like Reg's, its forearms can be launched and retracted. It walks on two legs, which are much smaller in comparison to the rest of its body.
Noting some of the similarities in their design and build, it said that it and Reg could possibly have the same creator.
