(Capcom's primary storyline)
|This section is not intended for generic trivia - defined here. It is only a placeholder for notable information not yet placed into other sections.|
- Jill's character model from the 2002 Gamecube Remake onwards, is based on actress Julia Voth.
- Jill's face model in Revelations and Operation Raccoon City is Bosnian model and actress Amra Silajdzic.
- Jill Valentine has the distinction of being the first character to use profanity in a Resident Evil game, saying "shit" every time her radio failed to contact Brad.
- In Resident Evil 2, one can search Jill's desk in the S.T.A.R.S. office of the Raccoon City Police Station. On her desk is a picture which, when examined, is described as her being with a young man, possibly her boyfriend. Nothing else is known about the man. Jill doesn't acknowledge the photo when she retrieves a lock pick from her desk in Resident Evil 3: Nemesis.
- Just like Chris Redfield's outfits have green as their primary color, most of Jill's outfits have blue as their primary color.
- In Dead Rising, also developed by Capcom, Jill's name is used as a cameo. A restaurant called Jill's Sandwiches is seen, this pokes fun at the infamous Barry Burton line in Resident Evil 1: "You were almost a Jill sandwich". And upon closer inspection a description of the restaurant owner "Jill" reveals that "Jill is a master of Sandwich making" which also pokes fun at more of Barry's dialogue.
- Jill is apparently ambidextrous as she is seen firing a Sig 556 with her left hand on the ending for Desperate Escape. There is a picture of her holding an M92F with her right hand in Resident Evil 5 as well.
- Jill is naturally a brunette, but the actress who plays her in the Resident Evil intro is shown to have slightly longer blonde hair. During the game however she is a brunette. In the Resident Evil remake she is portrayed with a short bob haircut - similar to her alternate outfit from Resident Evil. In Resident Evil 5, she is blonde again, but it is due to her time in cryostasis (which also made her skin pale).
- In Resident Evil 2 & 3, Jill's discarded Beret can be found lying on her desk.
- Jill was the first Resident Evil character to appear in the Versus series of fighting games, appearing in Marvel vs Capcom 2: New Age of Heroes, which portrayed her in her S.T.A.R.S. Uniform. She would later re-appear in Marvel vs Capcom 3: Fate of Two Worlds alongside Chris and Wesker, in her Resident Evil 5 incarnation
- Jill is pictured on the cards in SNK vs Capcom: Card Fighter's Clash, SNK vs Capcom: Card Fighters Expand Edition and SNK vs Capcom: Card Fighters DS in both her Resident Evil and Resident Evil 3: Nemesis attires.
- If a player completes Veteran Difficulty and logs into PlayStation Home, the player will be awarded with a Jill Valentine decoration trophy. She will be wearing her BSAA outfit with her natural hair color.
- At the moment, Jill is the character with the most numbers of voice actresses. In total she had seven different voices: Inezh, Catherine Disher, Heidi Anderson, Tara Platt, Patricia Ja Lee, Michelle Ruff & Kari Wahlgren.
- Jill appears in the crossover game Project X Zone alongside Chris in their Revelations outfits
- Jill makes a cameo in Capcom's video game Under the Skin.
- Jill appears in the Capcom's mobile game in 2017, Puzzle Fighter.
Jill's depiction over the course of the series has gone through minor changes while still maintaining a level of consistency. All of her default outfits are variations of blue. Her dress attire ranges from tactical gear to sleek and sexy. In the original Resident Evil her hair was long, but tucked into her beret while in the remake, Resident Evil 3: Nemesis, Resident Evil: The Umbrella Chronicles, and Resident Evil: Operation Raccoon City her hair was in a bob. Resident Evil 5 marks the introduction of Jill going from brunette to blonde as a result of experimentation done on her body. In her most recent appearance, Jill is shown to have grown out her hair and tie it up in a ponytail similar to Claire Redfield. In Resident Evil: Revelations, a prequel to Resident Evil 5, her hair is brown again but still in a ponytail.
Jill's standard and most well-known outfit is a pair of blue assault pants with a light blue formfitting shirt and shoulder/neck armor, completed with a blue beret on her head. In addition to her S.T.A.R.S. uniform in the first game, Jill wears a casual outfit consisting of jeans and black shirt. In Resident Evil: Director's Cut, she wears a sleeveless blouse with the S.T.A.R.S logo on the back along with jeans and boots as a default outfit in the game's Arranged Mode. The Sega Saturn version of the first game also featured Jill in an alternate version of her S.T.A.R.S. uniform.
In Resident Evil 3: Nemesis, she wears a blue tube top, black mini-skirt, white sweater wrapped around her waist, and brown tactical boots as her default outfit. This is also a well-known outfit and is the outfit worn by Sienna Guillory in the second live action film. She has a total of five alternate outfits (eight in later versions), including her original S.T.A.R.S. uniform, a police mini-skirt, a biker outfit, and a disco outfit. The Resident Evil remake featured her standard Resident Evil 3: Nemesis outfit and a new military outfit.
In Resident Evil: Deadly Silence (the Nintendo DS port of the original), Jill wears her original casual outfit, as well as a revealing policewoman uniform in the game's Rebirth Mode.
In Resident Evil: The Umbrella Chronicles, Jill wears a purple and blue vest along with white jeans and snow boots. This winter attire is reminiscent of her mission being set in Russia.
In Resident Evil: Revelations, Jill wears a pale blue long sleeve shirt with a blue undershirt, gray pants and black shoes. This outfit bears some resemblance to her S.T.A.R.S. uniform and is not seen wearing a beret early in the game and later changes to a blue and black BSAA wetsuit, with black diving boots for her mission to the Queen Zenobia.
Her blue and black BSAA wetsuit is later used in her crossover appearance in Project X Zone and Project X Zone 2 and her playable appearance in Resident Evil: Revelations 2's Raid Mode.
In Resident Evil 5, Jill wears her BSAA uniform in Revelations, with a blue cap as an addition. This is her outfit in Lost in Nightmares and as part of Chris' flashbacks.
After being taken by Wesker, she is stripped of her uniform and fitted with a skin tight indigo blue and black battle suit. Her disguise over the battle suit in Kijuju includes a long cloak and a beak-shaped mask. Because of the experiments performed on Jill's body a number of changes occurred. Her time in cryostasis caused a pigmentation abnormality to her hair and skin transforming Jill from a brunette into a pale blonde. An external device was embedded into Jill's chest to brainwash her into an obedient super soldier for Wesker and Excella. Once the device was removed it left a scar in the center of her chest where it had once been attached (not shown in Mercenaries).
Her skin tight battle suit is later worn by Sienna Guillory in both fourth and fifth live action films as the color of her suit is purple instead of indigo blue and black and the external device on her chest is replaced with a detachable red scarab device. But in her battle against Alice, the red scarab device was removed by Alice and is able to destroy the device to make Jill returns to normal.
In Marvel VS Capcom 3: Fate of the Two Worlds and it's updates, Jill is playable in the game and her outfit is from her Resident Evil 5 appearance.
