Shubs were a race of beings that were involved in the Third Reconciliation of the Meketrex Supplicants. Gozer ended their existence alongside the Zulls by taking the form of a giant Sloar. It was said the Shubs and Zulls "knew what it was to be roasted in the depths of a Sloar." Not much else is known about this race, and this information was completely coming from Vinz Clortho while he possessed Louis Tully in 1984.
- Shub could be a reference to Shub-Niggurath, also known as "The Black Goat of the Woods with a Thousand Young." The "Shubs" in question might be one of these young or possibly a follower of Shub-Niggurath. Lovecraftian themes have popped up in various Ghostbusters media in the past, such as the Ghostbusters facing Cathulhu itself in the The Real Ghostbusters.
- On page 12 of Ghostbusters Issue #8, Shubs are referenced on one of the cans in the garage bay.
- Vinz Clortho (1999). Ghostbusters - Chapter 20: Keymaster (1984) (DVD ts. 1:01:17-1:01:37). Columbia Pictures. Vinz says: "Gozer the Traveller. He will come in one of the pre-chosen forms. During the rectification of the Vuldronaii, the Traveller came as a large moving Torb! Then during the third reconciliation of the last of the Meketrex supplicants, they chose a new form for him, that of a giant Sloar! Many Shubs and Zulls knew what it was to be roasted in the depths of a Sloar that day, I can tell you."
