Ghost (must trap)
Slimer (also known as Onionhead and Little Spud) was a ghost made up of pure Ectoplasm and the first ghost successfully captured by the Ghostbusters. Slimer is well known for his gigantic appetite and the slime he leaves behind when he passes through solid objects.
Slimer 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 eating food. 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 couldn't keep the ghost a secret anymore and called the Ghostbusters. However, the Ghostbusters had not yet fully tested their equipment and weren't completely prepared for a full capture. Ray was the first to find Slimer, but missed him and Slimer escaped into the next hall, where he slimed Peter Venkman.
After many errant shots and the resulting destruction, Slimer flew into the Alhambra Ballroom where the Ghostbusters made another attempt at capture. Though Slimer is at first tossed around by some more missed shots, the Ghostbusters eventually manage to get him in the streams. Slimer was then caught in the Trap and put in the storage facility. However, he was released with the many other ghosts when the storage facility was shut down by Walter Peck. Slimer occupied a hot dog cart on on 1221 Avenue of the Americas in front of the Rockefeller Plaza. When the Hot Dog Vendor opened the cart, he was naturally shocked to see a ghost. After the Ghostbusters defeated Gozer and left Central Park West, Slimer was sighted in the area.
Slimer seemed to be a pet to the Ghostbusters, though it's unknown what he had been doing since the Ghostbusters were put out of business years ago. Slimer did resurface after the Ghostbusters started up again and had apparently gotten much fatter in the span of five years. Throughout the Vigo incident of 1989, Slimer interacted with Louis Tully. The two first met when Louis caught Slimer eating his lunch, to which the two of them fled in fear. On New Year's Eve, Louis decides to take up a Proton Pack and help the Ghostbusters. In an attempt to patch up their initial misunderstanding, Slimer helped an exhausted Louis by giving him a ride to the Manhattan Museum of Art (to which Louis wonders how he got his license). It seems likely Slimer had simply commandeered an abandoned bus from the havoc resulting from Vigo's Mood slime assault.
Ghostbusters: The Video Game (Realistic Version)Edit
At some point, Slimer was recaptured and kept in a Paranormal Containment Research Tank in the Firehouse in the lobby. Egon Spengler used him for various paranormal studies (sometimes noted that this is a nod to The Real Ghostbusters shows take on Slimer). On Thanksgiving weekend 1991, Slimer was playing with Peter Venkman's ESP cards inside the Paranormal Containment Research Tank.
The Psi Energy Pulse damaged the Tank and Slimer escaped. The team finds him looking at the Containment Unit. When the Rookie takes a shot, Slimer avoids it and the Proton Stream hits the Unit, releasing the Sloth Ghost. Rookie and Ray pursued Slimer into the Sub-Basement but it escaped through a wall. After the Sloth Ghost was recaptured, the Ghostbusters headed to the Sedgewick Hotel on Ray's hunch Slimer would return to his old haunt. Sure enough, Slimer was found by Ray, Peter, and Rookie eating and drinking off someone's tray in front of Room 1218. Rookie took a shot but Slimer ran for it and tried to hide. Rookie roused him out and Slimer flew off towards the elevators where he descended back to the ground floor (but not before sliming Peter for a second time). Slimer is joined by Bellhop Ghosts. With renewed paranormal activity, Egon opts to split up. Rookie and Peter are tasked with recapturing Slimer. Peter believes he's feasting in the Alhambra Ballroom but the manager John O'Keefe bars entrance. Peter regroups and leads Rookie through the kitchen to access the other entrance to the ballroom. Rookie and Peter successfully traps Slimer.
Slimer is placed back into a working Paranormal Containment Research Tank when the team returns from Times Square. When Ivo Shandor shut down the containment grid, Slimer is among the escapees. After the Ghostbusters destroy Shandor and return to the physical plane, Slimer slimes Ilyssa Selwyn just as she and Peter are about to kiss in Central Park.
Secondary Canon HistoryEdit
Legion Mini SeriesEdit
Slimer fell into the Ghost Legion who allied with Michael Draverhaven. From a hangar at the JFK Airport, Michael kept Slimer at his side as he coordinated attacks on New York City and the Ghostbusters. He used Slimer's Ectoplasm to construct a simple map of the city and to restrain Ray. When the other Ghostbusters arrived, Peter relished the chance to take another shot at Slimer. In the aftermath, it appears he evaded capture and fled the hangar with the rest of the ghosts.
Ghostbusters: The Video Game (Stylized Version)Edit
He is more like a pet in this version evidenced by three dog food bowls with him in the Paranormal Containment Research Tank. Much like the Realistic Version, he escapes from his tank when the Psi Energy Pulse passes through the Firehouse. However, he only stays shortly to waive goodbye to the Ghostbusters then leaves for the Sedgewick Hotel. Peter and the Rookie recapture him, and he is placed into another research tank. When the ghosts are released from the Containment Unit, Slimer escapes again, but at the end of the game, Slimer doesn't slime Ilyssa. Instead, he reappears above the garage bay in the Firehouse. The credits roll while the Rookie(s) try to catch him again.
Ghostbusters: The Video Game (Stylized Portable Version)Edit
He is much like the normal Stylized Version. However, the relationship as a pet/research subject wasn't suggested in dialog.

Dealing with the Supernatural
- Ghost (must trap)
- Attacks: Melee, Range
- Weaknesses: Proton Stream
After the "Shandor Incident," Slimer proved to be a problematic repeat haunter. He began terrorizing an apartment complex occupied by Alan Crendall, who thought it was a curse for what his Uncle Janosz Poha did in 1989. One week later, Alan told Winston about his problem. Winston and Peter investigated the following afternoon. While Winston scanned the Crendall's unit in room 426, Peter checked next door in 427. Peter ran into Slimer and flew through the wall into 426.
An hour or two later, Winston and Peter were still having an unusually difficult time in capturing Slimer. In a shocking display, Slimer was able to pull free from the Proton Stream. Using Winston as bait, Peter managed to ambush Slimer and trapped him. Slimer was returned to a Paranormal Containment Research Tank in the Firehouse. Egon later postulated the current uptick in P.K.E. made Slimer stronger than usual.
In the fall, after the Ghostbusters' trip across the nation, Egon used Slimer as a test subject for his studies on the Ghost Smashers. For several days, Egon experimented on explosive dispersal of mid-range ectoplasmic manifestations. Slimer proved to be an excellent test-subject. Egon concluded the time to reconstitution in a 180 cubic foot enclosure averaged at around three hours and 47 minutes. From that data, he extrapolated when the entities atomized by the Ghost Smashers would also reconstitute. When Egon wasn't looking, Peter dispersed Slimer for fun.
During the tail end of the Tiamat incident, the battle between the Ghostbusters and the Gozer-Tiamat-possessed Ray created another chance for Slimer to escape from the Paranormal Containment Research Tank. Three months later, Slimer was seen flying past Saks Fifth Avenue. At some point after the Saks Fifth case, Slimer returned to the Sedgewick Hotel. He was subsequently recaptured and returned to the Paranormal Containment Research Tank.  During the Chi-You incident, Slimer snapped at Michelangelo. Ray demonstrated the effects of certain books on ghosts. He waived Fairfax's Demonologia at Slimer who recoiled and shielded his eyes. Once the demonstration was over, Slimer made faces at Ray.
Ghostbusters: Sanctum of SlimeEdit
Slimer randomly appears in certain levels (Level 1: Training Day, Level 2: Asylum Brawl, Level 3: River of Ooze, Level 7: Back to the Sedgewick, and Level 9: Lair of the Huge Spider) but leaves after some time or taking a few blasts from the players. He is never dispersed nor trapped in the course of the story.
Continuing from the first movie, Slimer actually stuck around the Ghostbuster headquarters. He apparently was feeling lonely and the Ghostbusters were the only ones who paid attention to him. He mainly stayed hidden until being drawn out because of his appetite. The Ghostbusters at first reacted negatively to him, but as he hung around they started to tolerate him and even treat him like a friend. Ray gave him the name "Slimer" (just to annoy Peter). Slimer was finally accepted as a pet ghost after helping the Ghostbusters stop the Anti-Ghostbusters. Throughout the years, Slimer aided the Ghostbusters whenever a ghost was needed for the situation. Because he helped the Ghostbusters, Slimer had a large number of problems of his own. Many ghosts considered Slimer a "traitor" amongst ghosts for his compassion with the humans. This often put Slimer on bad terms with many villains who faced the Ghostbusters.

Ghostbusters (Beeline mobile game)Edit
You capture Slimer once, at the start of the game.
Tobin's Spirit Guide
Fondly dubbed "Onion Head" he's haunted the HQ for years. Throws slimeballs around and provides daily rewards.
Throughout the first film, Slimer appears to lack intelligence and was all about getting a good snack. It was normally a shy ghost but was not afraid to slime when cornered. In the second movie, it appears that Slimer had become more intelligent and could drive a bus. So far, in the video game and cartoon he has grown in intelligence and seems to understand basic human concepts.
Slimer is classified as a focused, Non-Terminal Repeating Phantasm, or a Class 5 Full Roaming Vapor. And a real nasty one at that.
Dan Aykroyd reportedly referred to Slimer as "The Ghost of John Belushi". In the script for Ghostbusters, Slimer is never actually called by any name, so is never given one. The creature's original moniker was simply The Onionhead Ghost, which the film crew semi-officially dubbed him because of his horrible odor, which he used to scare a couple in a scene cut from the original movie.  In early drafts, Slimer was vaguely described as an 'incredibly foul-smelling amorphous vapor'. In July 1983, the final design came along and the 'green, potato-shape' was incorporated into the script.  In total, three large scale Onionhead ghosts were created, each with a different expression and/or task. One was for smiling, one was for looking scared, and one was for drinking. A miniature was made for long shots of it flying around the hotel chandelier but it wasn't used.  The Onionhead form was cast in the form of a foam latex suit but actual expressions were done with cable mechanisms. 
For the live action set, in the scene where Ray spooks Slimer, a room service cart trailed after him. The cart was motorized and piloted from underneath by one of Chuck Gaspar's crew. Naturally, when the cart crashes, the driver is not present. The shot of Slimer phasing through the wall was shot at Entertainment Effects Group and incorporated optically later on. 
During effects photography, the suit was worn by Mark Wilson. Wilson's legs were concealed with black velvet. A team of puppeteers dealt with facial expressions. Wilson worked with oversized props so the ghost would appear smaller after composited into live action. 
When the cartoon series was produced, in response to the name much given to the character by audiences, the writers renamed the green ghost "Slimer", and the name stuck on all subsequent Ghostbusters properties (he was even named Slimer in the end credits of Ghostbusters II, but a character never actually referred to him as Slimer in the film canon until Ghostbusters: The Video Game), although he 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.
Slimer wasn't always a definite part of the Ghostbusters II script. It was a matter of considerable debate if he should appear at all. Slimer's appeal, luckily, was very universal among children thanks in part to the first movie and The Real Ghostbusters. Slimer was given a subplot and written into movie - Slimer would eat various foods in the Firehouse while Louis Tully would try to trap him then they would become friends. Michael Gross requested elements of the animated version of Slimer to be incorporated into the movie. Tim Lawrence and Thom Enriquez worked on a new design. Meanwhile, Bobby Porter was called into portray Slimer. Some of the technology and techniques used for Nunzio Scoleri were used for Slimer - the divided head construct, pneumatic jaws, SNARK and a fat suit - a departure from the first movie where he was hand puppeteered. Then Slimer was removed from the script. Porter was released. 
Two weeks later, Slimer was back in the script and had a bigger role. However, Porter was no longer available. Effects coordinator Ned Gorman remembered working with Robin Navlyt on "Willow" and she was brought in. Surprisingly, she was the same height as Porter and fit into the suit very well. Chris Goehe and his mold shop crew made a full lifecast on her and Al Coulter worked on a new skullcap. The Slimer shoot was finished close to the first day of shooting. Michael Gross was onhand to push the crew to keep Slimer subtle and reduce any complicated approaches to moving him.  Slimer's segments were deemed intrusive by preview audiences.  During editing, Ivan Reitman decided to limit Slimer's role even though all scripted scenes were filmed and completed.  Ultimately, Slimer's scenes were trimmed to two brief shots plus one during the end titles.
- During pre-production, Ivan Reitman remarked Slimer was sort of like Bluto in the film "Animal House" like the ghost of John Belushi. Dan Aykroyd never argued with that point.  Since then, Slimer has been described as "The Ghost of John Belushi" by Dan Aykroyd in many interviews.
- Dan Aykroyd described Slimer as a vapor - a kind of confluence of stored up psychic energy, an accumulation of spirits that haunt the hotel who doesn't want to leave. 
- Thelma Moss, of the Parapsychology department at U.C.L.A, told Harold Ramis Slimer was similar to a classic type of haunting known as 'hungry ghosts' - a ghost who just eats and drinks. Ramis admitted they didn't know about that when they wrote the script. 
- Ivan Reitman provided all of the unearthly voices, such as Dana's demonic Zuul voice and Slimer, except for Gozer's.  
- Slimer's ectoplasm was derived from methylcellulose ether -- a powdered thickening agent used in pharmaceuticals and food products. 
- The sequence in the first movie when Slimer flies around the chandelier, it was originally supposed to be a miniature but it was too big for the shot. Due to time constraints, a peanut was spray painted green and used. 
- As an afterthought in postproduction, Ivan Reitman came up with the idea to include Slimer in the last shot of the first movie. 
- In the Novelization of the first film by Larry Milne and early scripts of the first movie, Silmer is described as being yellow. 
- Asides from being able to render himself incorporeal, Slimer appears to have low-level telekinetic ability. During his first encounter with Ray, Slimer flees, dragging a room service cart behind in tow. Which collides with the wall as he phases through it. This may also explain how he's able to work the foot pedals on the bus he commandeers to help Louis.
- In the Ghostbusters Role-Playing Game Series, Slimer's presence in the world of the living was credited as a side-effect of cult rituals.  These cult rituals were likely performed in Slimer's case by the Cult of Gozer, lead by Ivo Shandor. Gozer, also known as "Lord of the Sebouillia", may-in turn-have influenced the name. Sebouillia in the Ukrainian language translates as "onion." Thus, Slimer's coined term, "Onion Head."
- In The Real Ghostbusters Marvel UK series, Slimer was revealed to be the ghost of King Remils (an anagram of Slimer). The canonicity of this comic strip is doubtful though. 
- In the 1992 Annual by NOW Comics a profile of Slimer, stated, "In life he was an extremely greedy and obese man. After death he forgot all things about his life, even his own name, except the urge to continue eating."
- At the end of the theater version of Ghostbusters II, Slimer comes out from behind the Statue of Liberty and flies right into the camera just like how he did at the end of the first movie. The VHS/DVD versions omits this and just ends with a pan up to the statue's head then a fade to black.
- In the Ghostbusters II deleted scene "Louis' Secret", Janine downplays the threat of Slimer to Louis. 
- Slimer is shown in the trailer for "Ghostbusters: The Video Game," flying at the viewer in a manner similar to the end of the first movie, before a transition into the traditional Ghostbusters emblem.
- Slimer makes a cameo on Ghostbusters Issue #9 Cover RI-B, Spook Central variant.
- On Cover RI of Ghostbusters Issue #15, Slimer makes a cameo.
- On page nine of Ghostbusters Volume 2 Issue #9, there is a photo of Slimer on the center bottom section of Egon's board.

Paragraph reads: "Although never specifically named in the film, the hotel apparition was to become known within the production unit as the Onionhead ghost -- so dubbed because of the horrible stench which emanated from it, rather than any physical resemblance to an onion. Though the malodorous aspect of the creature was dropped when the newlywed scene was cut -- primarily because to visually support the notion would have required massive amounts of exacting, hand-rendered animation during the postproduction effects phase -- the name 'Onionhead' persisted among members of the crew."

Even so, we never officially said that and we never mentioned it in the script. It was just one way to look at the character, because Onionhead's grossness is like Bluto's in Animal House. We certainly never expected anyone to recognize him as such, although somehow the word did get out and we received some calls from a few newspapers saying they'd heard we had the ghost of John Belushi in our movie."
