Jonesy, also referred as Jones, was a cat kept aboard the USCSS Nostromo as Ellen Ripley's pet. While the cat's official purpose was to control rodents aboard the ship, he also served as a source of relaxation and entertainment for the crew.
Jonesy and Ripley were the only two to survive the Nostromo incident caused by a Xenomorph and the ship's subsequent destruction.
Owing to Jonesy's small size and mass, he comfortably shared a hypersleep capsule with one of the crew members during the Nostromo's long journeys. While the Nostromo's crew were hunting for the Alien, Jonesy came up on the motion tracker made by Ash and was mistaken as the Alien. Ripley and Parker sent Brett to catch Jonesy. When Brett finally caught up with Jonesy in a cargo room, he started to try to coax the cat out to make sure it didn't set off the motion tracker again. Jonesy noticed the strange silhouette behind Brett and began to hiss. By the time Brett turned around, the creature attacked him and carried him up into the air ducts with Jonesy witnessing the ordeal. Jonesy was attacked by the Alien when Ripley left him in his cage, but the Alien left him alone as Jonesy was apparently of little interest to the creature and he survived the incident unscathed. He was put in cryo-sleep after escaping the Nostromo with Ripley.
57 Years laterEdit
Ripley and Jonesy remained in cryostasis for 57 years. The salvage crew that picked them up initially thought the unusual readings from the cryotube was that of an alien life form, but visual inspection revealed to them that they were simply reading the human and feline sets of DNA as one organism. After their recovery, they were reunited in the hospital of Gateway Station by Carter Burke. Jonesy then went to stay with Ripley at her new apartment. When Ripley must return to LV-426, she fondly curses him and says, "And you, you little shit-head, you are staying here". It is unclear what became of Jonesy after Ripley's assignment to the USS Sulaco and subsequent death on Fiorina 161.
- During the scene when the Alien descended down to Brett from behind, to get Jonesy to react fearfully to the descending Alien a German Shepherd was placed in front of Jonesy so it would react fearfully to the descending Alien. A screen was placed between the two, so the cat wouldn't see it at first, and came over. The screen was then suddenly removed to make Jonesy stop, and start hissing.
- Jonesy has been referenced several times in the Halo universe, a series of games by video game developer Bungie.
- Jonesy has been referenced in World of Warcraft and can be found in Dalaran in the The Legerdemain inn resting comfortably on a ledge as you go up the stairs to the second floor.
- Since a different cat was used for the sequel (given the prolonged time during the filming of the two films), Jonesy appears to be skinnier in the sequel than in the original film.
- Since he was in cryostasis for the past 57 years, Jonesy is probably the cat with the longest lifespan in the history, being around 60 years old when Ripley left him.
- Potentially the last survivor of the Nostromo.
- Jonesy stars in his own graphic novel, titled Jonesy: Nine Lives on the Nostromo, coming October 2018.
