|Specifics: This is for Crossing Over|
This article is for the Extreme Ghostbusters Kylie Griffin. To read about the version seen in IDW Comics go here.
Kylie Griffin is one of Egon's four students who became a Ghostbuster.
In 1987, when Kylie was a child, her only friend was a seven year old boy named Jack. Kylie was visited by the Grundel but she was strong of mind and resisted his calls. The Grundel then went after Jack and turned him. Jack went missing and was never found. No one believed Kylie's account of what happened either. She blocked the memory and kept it repressed for a decade.  
Prior to Kylie becoming an Extreme Ghostbuster, Kylie's parents divorced and she became close with her Great Grandmother Rose.   Rose died sometime in 1996 and Kylie now lives with her cat, Pagan. She became a "Brainiac" (genius) with a scientific interest in the paranormal. 
In the new Ghostbusters team, Kylie usually takes on the role as the paranormal expert of the team whenever Egon was not present. She is also the team's primary member who holds and deploys the ghost trap. Rather than having a full sized proton pack, Kylie carries a smaller lighter pack which she attaches to her belt and carries the new ghost trap on her back. Her Proton Pistol weapon is a pistol version of the full size proton pack and blaster. It is powered by a small proton pack attached to her belt. The Trap is worn like a backpack. She is the only character to have a completely different uniform, other than Eduardo, than the other Ghostbusters, which is customized to fit her small build, and basically consists of a form fitting body suit and torso armor.
In an alternate future, Kylie became a highly revered figure. She prophesied she would one day return and help end the tyranny of Tempus. After her death, a group of rebels kept her cause alive and preserved some of her belongings, including her journal. Due to a Time Slip on July 30, 1997, Kylie was stuck in the future, fulfilling her future self's prediction. Following instructions left by the other Ghostbusters, Kylie led the rebels to Central Park to unearth a Proton Pack time capsule. Once it was found, Kylie coaxed Tempus into following them to the ruins of the Firehouse where another Time Slip was generated and Tempus could be re-merged and trapped. Kylie returned to her rightful time.
Kylie's childhood trauma was revisited when she encountered Jack, now a Grundel. She confided in Roland and he helped her disobey direct orders never to open the Containment Unit and interrogate the original Grundel. However, the Grundel facilitated its escape by enthralling Casey Jackson, Roland's younger brother. The Extreme Ghostbusters rushed to Roland's home to protect Casey but they were too late. The original Grundel confronted Kylie alone and planned to torture her. Luckily, Roland returned in time and saved Kylie. Together, they trapped the Grundel.
Kylie enrolled in college and began working towards a Bachelor of the Arts in Parapsychology.  At the Bronx Zoo, Kylie observed Ghash with her P.K.E. Meter while Garrett blasted it. It suddenly flew away quickly and Kylie couldn't get any readings on it. Just as quickly, she picked up something powerful. Proteus arrived in search of a team of Ghostbusters he intended to imprison. After Proteus teleported away, Garrett declared he had him right where he wanted. Kylie didn't believe an ounce of what Garrett said. Kylie helped trap all of Connla's Army on Liberty Island in the prime dimension weeks away from Halloween. The prime version of Kylie wasn't sure if spreading the portal technology around was a good idea. Kylie mused the next step would probably be a convention and din't find it too appealing. The other Kylie agreed. Egon Spengler, of the prime dimension, asked the Extreme Ghostbusters for their help in retrieving ghosts that escaped from the Containment Unit and escaped into the multiverse. All of the teams involved in the operation gathered in the Warehouse.
The Extreme Ghostbusters chimed in on the time travel question poised by the Ghostbusters of 50-S. Kylie stated they were trained by Egon and Eduardo pointed out the Egon on the Real Ghostbusters of 68-R was a younger version of their Egon. The prime dimension's Egon reiterated the teleportation unit could not time travel but time was a dimension they could access in so far as they went to parallel realities that could be further ahead or further behind what they knew as the present but no action they took had an effect on their timeline. A field team consisting of Ray Stantz, Samuel Hazer of Dimension 50-S, Peter Venkman of Dimension 68-R, Kylie Griffin of Dimension 68-E, Erin Gilbert of Dimension 80-C, and Kylie arrived in search of a ghost in Dimension 00-D. Kylie noticed they were in a rather gloomy forest. Samuel thought the Kylies would feel right at home. They didn't and messed with him. Kylie stated she loved ponies. The other teased sunshine was her jam. Kylie couldn't believe she had "my jam" in her vocabulary. Ray asked them to stop. Eventually, Erin asked if they had any indication of what they were after, recalling her team was assigned to a mid-level Class 3. Samuel was excited about what it could be and proposed a betting pool. The Headless Horseman arrived, grabbed Peter 68-R by the hair, and rode off. Ray recalled when his team captured it outside of Tarrytown four or five years prior. Prime Kylie requested he tell the story after they recovered Peter 68-R. The others ran after them.
Kylie is shown to be very intelligent with a deep interest in the paranormal. She joined Egon's class Paranormal 101 due to her desire to learn more about it. She is shown to be an expert on the occult, and is shown to have advanced knowledge of paranormal phenomena including but not limited to; Spirit types, Witchcraft and Seances. She has a deep connection with her deceased Great Grandmother Rose and talks to her on occasion through journal entries. Kylie has a very no-nonsense take on her work with the Ghostbusters and is shown to have great respect for the ghosts and demons that the team is put up against. She also has great respect for those she considers knowledgeable, particularly in the paranormal such as Egon Spengler or Ray Stantz.
Relationship to Others
Kylie has a deep admiration for Egon Spengler and maintains a high level of respect for him often defending him in arguments about him among the rest of the team and is in awe of Egon when the series began but this soon shifts to a more equal footing, and becomes somewhat of the unofficial leader in the field of the paranormal, after Egon.
Kylie simply gets along with Janine Melnitz.
While the two constantly bicker, there is an underlying romantic interest between them. This is referenced in several episodes where Eduardo Rivera rescues Kylie from dangerous situations and vice versa. She is also shown to be concerned for Eduardo's safety from time to time albeit not as obvious or as frequent as Eduardo is for her. She is constantly exasperated by him and vice-versa although they occasionally flirt sub-consciously with each other.
Kylie works well with Roland Jackson and often defends Roland against criticism and blame even if it's self-criticism often telling him that "it's not your fault".
Kylie is okay with Slimer, although he grosses her out. She's not fond of him sliming her books.
Peter Venkman likes Kylie's take-charge attitude.
Kylie was not part of the original concept for Extreme Ghostbusters. A precursor to Roland was female and there was Lucy, a precursor to Garrett.  Before the show was pitched to a network, Fil Barlow did an initial sketch with three female characters, Lucy, a Goth, and a "Troubled" third that Executive Producer Richard Raynis rejected because it coincidentally was a close representation of a family member of his. Raynis liked the Goth and wanted to develop her some more. Raynis wanted her to be diminutive.  The original concept design of Kylie had her in a costume that was rejected but later became one of her civilian outfits on the show.  She also was armed with a suction weapon designed by Matthew Brady, on artist on character designer Barlow's team. The weapon was later used as a design for the Proton Packs in the Trendmasters Extreme Ghostbusters Classics: Action Figures. In 1996, Fil Barlow prepared Kylie's main model pack while still in Australia, including expressions to assist the animators.  At first, there was resistance from the Sony storyboard artists when they first had to work with Kylie but by the end of the season she was accepted.
