One of the crew members of the hovership Nebuchadnezzar is named "Apoc". What is the meaning/significance of that name? Is it short for something, or perhaps an acronym? A recent answer suggests that it is short for "Apocalypse". Another website suggests that it might reference either "apocalypse", "apocrypha", or "apocryphal".
While researching this question I found an old script of The Matrix in which Neo mentions that Apoc wrote a "Four Horsemen" virus. The script does not mention anything else about this virus, but the name of the virus combined with Apoc's name means that both are almost certainly a reference to the Biblical Book of Revelation (also called the Apocalypse or the Apocalypse of John) since the Book of Revelation includes the Four Horsemen of the Apocalypse. Therefore "Apoc" is short for "Apocalypse" rather than "apocrypha" or something similar.
