Lucifer's Rebellion was the code name for Jack's genocidal nuclear strike against humanity. This event led to the extinction of the human race as well as the decimation of most of that generation's furdom as well.
Background[]
After the murder of his true love Jill by a guard at the Miller Hill facility, Jack became increasingly unhinged, culminating in the murder of one of his creators. Though his actions were covered up by Dr. Kane, Jack began secretly planning to supplant humanity as the dominant species on Earth. His early actions including being a charismatic leader for vat-born beings as well as peppering his private speeches with comments suggesting furry superiority over humanity, comments that alienated his advisors such as Central and Mr. Grimm who preferred peaceful coexistence.
Years after Central left his circle, she was murdered by anti-fur extremists, an action that devastated Jack and pushed him toward his final goals.
The Original Plan[]
Jack's goal was to secretly move furs away from human habitation, under the guise of creating fur-friendly communities away from human prejudice. The idea was for each community to secretly house survival shelters to hide away furs and supply them with food and medical equipment. Meanwhile, Jack would take advantage of humanity's desire to appear accommodating by having furs placed in various strategically important positions in government and commerce around the world, especially military positions. Once all the pieces were in place, Jack would order the nuclear assault on humanity, destroying it while allowing furdom to rebuild from the rubble. Jack would then be the leader of this new society.
The Result[]
Jack was never able to implement his plan to its full extent as his advisor Grimm had discovered his actions months before he was ready to act and fled to warn human authorities, forcing his hand. Completely megalomaniacal and committed to his cause at this point, Jack was forced to launch the assault early, at the cost of 80% of furdom, including himself and Fiver. This action doomed humanity and left the remaining furs to piece together their existence on their own, resulting in the eventual repeating of the same mistakes as before.
