Membrane is a scientist who hosts the popular television show Probing the Membrane of Science and is the father of Dib and Gaz. Membrane's scientific abilities are offset by incredibly poor parenting: his primary method of managing his children is by way of a floating digital projection screen-and his messages to them are often not only prerecorded, but woefully out of date. He has sometimes urged Dib to give up on the paranormal and focus on "real science". His scientific achievements can range from useful to bizarre, ranging from restoring power during a blackout to "SuperToast".
