Although Slimer was referred to as "The Green Ghost" early in the related toy line, in later releases of his first figure, an extra label was applied specifying ""Known as 'Slimer' in the Real Ghostbusters TV show"". The in-narrative explanation for Slimer's name was revealed in the eleventh episode of "The Real Ghostbusters", "Citizen Ghost" (first broadcast on November 22, 1986). A flashback depicting how the Ghostbusters made friends with Slimer reveals the ghost was so nicknamed by Ray Stantz. Throughout the first film, Slimer appears to lack intelligence, only caring about gaining food to eat. In the second movie, Slimer appears more fat and more intelligent, and could drive a bus (Louis wonders who gave him a license). Slimer is shown to be caring in "The Real Ghostbusters", showing compassion from Ray Stantz, and kissing Janine. The 2016 reboot features a different incarnation of Slimer, who savages a hot dog cart and, after an attack by the Ghostbusters, steals the Ecto-1 to go on a joyride with his girlfriend, Lady Slimer, and other ghosts. His origins in the original timeline were explained by the Marvel UK comic book "The Real Ghostbusters" #22. It is explained that he was King Remils ("Slimer" backwards), an obese king who died of heart failure, while a deleted scene from the 2016 "Ghostbusters" film was meant to expand on Slimer's rebooted continuity origins: when he was alive, Slimer was a gangster who killed a restaurant waiter that got his order wrong, resulting in his imprisonment and execution. After his death, the Ghostbusters encounter him haunting the same restaurant, but due to the experimental nature of their equipment, they inadvertently disfigure him, destroying his legs and turning him green, before he escapes. Voiced by Ivan Reitman, Slimer (not named until "The Real Ghostbusters") was a legendary ghost to all on the original staff of the Sedgewick Hotel. His usual territory was the twelfth floor, but his outings were usually non-violent and simply involved gorging himself on food from room service carts. As a result, the hotel was able to keep a lid on the supernatural problems for a while. For some reason, Gozer's approaching time of arrival provoked Slimer (and many other ghosts) into being much more active than usual. Eventually the staff could no longer keep the ghost a secret and called the Ghostbusters. However, the team had not yet fully tested their equipment and were not completely prepared for a full capture.
