Throughout the first film, Slimer appears to lack intelligence, only caring about gaining food to eat. In the second movie, Slimer appears fatter 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.
