The Pan-Dimensional Liquid Beast from the Mogadon Cluster was an unseen entity which attacked the Boys from the Dwarf one Christmas Day during the time that they had lost Red Dwarf and were searching for it aboard Starbug. Dave Lister used that Christmas as an example of how every day was just another slog through Deep Space, until Kryten reminded him about the attack from the beast. (RD: Out of Time, Series VI)
- The Pan-Dimensional Liquid Beast has never appeared on screen, and was only mentioned by Kryten when discussing the crew's bleak and monotonous existence. (RD: Out Of Time)
- Given that no aliens exist in the Red Dwarf universe, as frequently stated by creators Doug Naylor and Rob Grant, it can be safely assumed the Pan-Dimensional Liquid Beast was another form of GELF.
- It could be argued that as the creature exists outside of the Red Dwarf universe in several other planes of reality, it is therefore not bound to this rule.
- It is possible that is the same creature as the Vidal Beast of Sharmutt II mentioned by Lister in the Series VII episode ("Blue"), which Cat claimed "nearly killed us".
