Dematerialisation circuit
From Jenny Everywhere Wiki
Dematerialisation circuits were a key component of the Crew of the Copper-Colored Cupids' Fog Ships, being what allowed them to phase through dimensions. Although a hermetic vehicle built around the circuit was ideal for most beings (including Clockwork Cherubs), it was possible to travel across dimensions with just the circuit: Doctor Sigma fitted the robot CS-NA with a personal dematerialisation circuit keyed into his own systems, allowing him to dimension-travel at will, similar to a shifter.
