More than 20 possible licensed killers (and their survivors)

-"It" from It Follows. AKA "The Shapeshifter" (known as "The Enity" in the film). Its power could be shapeshifting, adopting the skin of a survivor on the currently played game, it won't be able to use pallets, heal, repair or sabotage. It has terror radius, confusing the other survivors, is the killer chasing that survivor?. Also, a survivor will start the game as "the infected" and the killer will be able to know their location anytime, anywhere, but the survivors can get rid of the infection by passing it to another survivor. Like in the movie, but without sex.
The weapon could be a med-kit, a flashlight or a toolbox.
After a seconds of finishing chasing a survivor or hooking them, the shapeshifter will change randomly its survivor skin.
If this killer shapeshift into Nea, she will become a true killer.

The survivor from It Follows; Jaime "Jay" Height.

-"Lori Spengler" from Happy Death Day. AKA "The Campus Mascot"/"The Mascot". The power could be related to the fact that the killer in the movie always knew where Tree was.

The survivor from Happy Death Day; Theresa "Tree" Gelbman. In the film she revives each time the same day after being killed, like in DBD. She could have perks based on the fact that she already knows how the killing works. Something related to time, or knowing the locations of the objects, or given that in the film each time that she gets killed she suffers less, she could resist more time in the hook.

• "McKayla Hooper" and "Sadie Cunningham" from Tragedy Girls. AKA "The Tragedy Girls"/"The Friends"/ or just "The Girls" . They would hold their hands and be controlled as the same killer. The social media and their followers were extremely important, they became killers in order to achieve fame, always knowing some secret facts from the murders. Maybe, their power could be a broadcast of their killings. Each time they were chasing, hurting or sacrificing survivors, their followers could increase, and their strengths would increase too. For instance, their terror radius could be reduced or their movements could accelerate.
  Since in their final massacre in the movie they block the gym doors (like in carrie) one of their perks could be that instead of 20 seconds, the exit gates needs 25s or 30s to open.

The survivor from Tragedy Girls;** Jordan Welch**

• "Billy Murphy" from The final Girls. (it's a killer really similar to Jason from Friday the 13th, he could be his substitute and could be bought.)

The survivor from The Final Girls; Max Cartwright

-"The Other Mother" from Coraline. AKA The Dollmaker/The Spider. As she was able to create dolls that were like spies, or even living copies of real people, her power could be the ability of placing surveillance dolls of the survivors. When a survivor were close to the doll, the other mother would be able to see their silhouette. Or, she could hang in hooks dolls that looked like a survivor in the game or leaving a doll in a dying state. Survivors would see the icon of a survivor being hooked or hurt. The difference between dolls and survivors would be in the eyes. Dolls would have buttons instead of eyes. She may be from a movie for kids, but she actually kills children, so, why not survivors?

The survivor from Coraline; Coraline Jones. Since in the movie her problem starts when she opens the small door that is linked to the other world, her perks would involve the hatch, like knowing its placement from the beginning, being able to open a hatch without any key if X number of generators are repaired or nullify the sound of an opened hatch for the killer.
Their style would be different from the characters of DBD, but there is a similar game called "Identity V" that uses characters similar to the Coraline style, so I can imagine this characters in the game. Given the fact that Coraline is a kid, seems unlikely to see this as a new chapter.

• "Lipstick-Face Demon" (AKA "The Demon") and "Parker Crane" (AKA "The Black Bride"/"The Bride**") from Insidious. The black bride could temporarily blind all survivors at the same time. If you as a survivor were repairing or healing, would become unable to see the skill check. And imagine if you were being chased. The power would have a large amount of seconds or even minutes to cool down.
  And with the demon I have no idea.

The survivor from Insidious; Elise Ranier. Since she is a medium, she could have perks that could nullify the perks of the killers, like the opposite to thanatophobia. Instead of receiving penalties to repair, healing and sabotage speeds for each injured, dying or hooked survivor, her perk could speed up repair, healing and sabotage for each survivor killed.

-"The Xenomorph" or "The Neomorph" (if it were cheaper) from Alien franchise. AKA "The Alien". The alien could have its power based on the ability of laying eggs if it was the queen or something related with its corrosive acid, reducing the area of skill checks or slowing the healing.

The survivor from Alien; Ellen Ripley (or another character from one of the new Alien movies) .

-"Mrs. Tredoni" from Alice, Sweet Alice. AKA "The Fanatic". She was obsessed with punishing sinners, maybe her power could be based on handicapping those survivors who has a low level of altruism. A killer that force you to help the other survivors.

The survivor from Alice, Sweet Alice; Alice Spages (even though she wasn't the real victim and has some psychopath behavior, could be a survivor without interest in helping her team mates).

• "Patti O'Connor" from Curtains. (in the film, the killer is known as "The Hag", but in DBD there's already a Hag. Maybe another alias would be better. In the film Patti was "The Comedian" ).
  Her powers could be related to something about theater or acting. Porcelain dolls also are related to her.

The survivor from Curtains; Samantha Sherwood(even though she was also a killer, she ends up being a victim of Patti, who murders the other actresses)

-"Pinhead" from Hellraiser. AKA "The Hell Priest" or "The Cenobite". Power related to torture? Something related to the hooks? Or maybe something to do with the puzzle box?

The survivor from Hellraiser; Kirsty Cotton.

• "Tristana Medeiros" from REC. AKA "The Possessed" or "The Ghoul". Her power could be related to the infection that she carries. She could infect the survivors and once they die, they could return as zombies controlled by an AI that would attack survivors and warn Tristana, but never putting them into dying state. And will walk slowly.

The survivor from REC; Ángela Vidal.

-"Lola Stone" from The Loved Ones. AKA "The Princess". She was obsessed with finding her blue prince, so her power could have something to do with an obsession. As in the film she kidnapped her obsessions, maybe she could make the obsession unable to help and also, unable to be helped during the reparation of a generator, or healing. And the obsession could be unhooked, but he/she couldn't unhook others.

The survivor from The Loved Ones; Brent Mitchell

-"Leslie Vernon (Mancuso)" from Behind the Mask: The Rise of Leslie Vernon. AKA "The Legend" ? (since he wants to become a legendary killer as the villains from slasher films...) He is a fan of the slasher films, he is able to plan his murders and achieve success, so he could fool the survivors placing fake chests, or hatches.

The survivor from Behind the Mask: The Rise of Leslie Vernon; Taylor Gentry.

-"Jack Torrance" from The Shining. AKA "The Writer". His weapon would be an axe. Any idea about his powers?

The survivor from The Shining; Wendy Torrance.

-"The Strangers" from The Strangers. Only one stranger would be played. The killer could have three skins, one for each stranger. It's hard to imagine their mechanics since they are similar to Michael Myers.

The survivor from The Strangers; any victim of one of their two movies.

-"Axel Palmer" from My Bloody Valentine (1981). AKA "The Miner".

The survivor from My bloody Valentine could be; Tom Jesse "T.J." Hanniger or Sarah Mercer.

And, also the killers previously mentioned by other users recently, like Ghostface from Scream with Nancy Prescott. Sadako from Ringu, and I will add Reiko as the survivor. Or The Nun, form The Conjuring franchise plus a survivor from the new film or Lorraine or Ed Warren.

And what about killers and survivors from TV Shows?

-"Demogorgon" from Stranger Things. AKA "The Monster". The demogorgon could place portals that would teleport the survivors from one place to another, instead of another dimension, as Freddy does.

The survivor from Stranger Tings; Jim Hopper (Eleven would be the best option, but she is just a kid so, better the sheriff)

-"Tate Langdon"(AKA "The Rubberman") and Dr. Oliver Thredson (AKA "Bloody Face") from American Horror Story. Since the Rubber man is a ghost, maybe he could go through objects, similar to the blink of the nurse, but without the jumps in the space. Bloody Face ideas accepted.

The survivor from American Horror Story; Lana Winters. (and which character from the first season for the rubber man?)

-"Boone Clemens" (AKA "The Red Devil" or "The Devil") or "Ingrid Hoffel" (AKA "The Green Meanie" or "The Meanie") from Scream Queens. During the series, there are a lot of characters that became killers, then, their power could consist in dressing a survivor with the costume of the killer. The survivor would be unable to attack, but neither to repair, heal, use pallets or sabotage. Can escape using the hatch if its opened or the exit gate. Also would have a terror radius. The survivor can undress them self, but the killer will receive a notification. The main goal of the power would be create chaos among the survivors, would be similar to "The Shapeshifter" from It Follows, were it become the survivor. They would be scared to work together.

The survivor from Scream Queens; (there are a lot of possibilities) Chanel Oberlin, Chanel 3, Chanel 5, and my favorite would be Denise Hemphill.

-"The Tuunbaq", from The Terror. AKA "The Bear". A killer that would look like and animal, it's not a were wolf but a polar bear like creature. Since it can be controlled by a shaman, a survivor could be untouchable until the rest of the survivors die, then the survivor with the role of shaman could be killed.

The survivor from The Terror; Francis Crozier or Lady Silence, the shaman. .
