Disguise is a mechanic I have been asking for a while. I remember thinking that from the Legion trailer that his power would be to disguise as a survivor. I would love the paranoia and distrust that would bring to the game.

Unfortunately something like jumping over walls probably isn't happening since it would be impossible to use on many maps. The killer basically wouldn't have a power on Lery's for example. It would also be pointless to crawl on those walls for any reason other than the cool factor.

The flamethrower example is basically just a new ranged Killer with a flamethrower skin. Plague already has a projectile stream. You're replacing vomit with fire.

Changing map objects in general is highly unlikely and would be limited to MAYBE switching a pallet from 1 location to another. We already got a taste of this with pallet Freddy, who was restricted to placing pallets to select locations that pallets could usually spawn at.

The disguise idea while neat... kinda comes undone with comms or simply players refusing to stay near teammates once the killer is identified as the disguise Killer. If I'm working on a gen and a teammate comes over... I'm leaving BEFORE verifying if they're gonna stab me or not. Same goes for mind control. "Hey guys, the killer is controlling Meg" is too strong of a counter.

Disguise would probably be the most unique idea that isn't in the game, but the difference between soloq and SWF would be even more enormous than normal.

Maybe a killer who isn't even on the map at all, but instead just summons different creatures to attack the survivors. That might be a bit too much like Evil Dead: The Game though.

A stealth sniper would be easy to write lore for. Very slow moving until he tags a survivor from range and goes in for the kill, but also he has to retreat if he gets spotted before a successful shot.

A stealth infector who can dart survivors with a poison they can spread to others / causes hindrance, but they don't know they have it until it actually afflicts them (so it has a meter like the plague before injuring, during this time survivor can spread it, but they don't actually know they have it if they didn't spot the killer).

A jumper/rampager, like existed in Deathgarden, who can vault across the map.

Someone who could alter the map, changing the way loops look and the position of windows, but I don't think the engine could handle it. Would probably be a good design for Freddy.

A killer who can teleport the survivors closer to him instead of teleporting to the survivors. The way I see this is that maps would be divided up into sections and the killer could target a section and teleport all survivors there to his section, being able to stop gen progress and not having to chase them, but if chooses the wrong section he's wasted time.

A killer who randomly shifts between other killers in the game (out of control Shang Tsung). Killers whose powers need to build / be set would probably need to be excluded (Oni, Trapper), but you could have a killer shift between the various stealth, ranged, anti-loop killers.

A weapons master killer who has weapons spawn around the map that he can gather to gain more powers, but survivors can also interact with the weapons to deny them to the killer.

A killer who can move the gens around the map (move them to spots they could have spawned in, or switch completed and non completed gens). This would be a bad design, but it would be unique.

A killer that can fly and has an aerial attack, but is incredibly weak when he is on land.

An arena based killer who can draw survivors into a maze/arena where they face off. Killer could get quicker downs this way, but if the survivor escapes its wasted time.

A killer who is unable to kick / regress gens, but instead when he 'kicks' a gen he charges his power (the closer the gen is to finished, the more power he gains). He then goes into an overdrive mode like Oni when fully charged where he can rush around the map (or deploy projectiles, some type of charged up power).

A killer with no power, but he gets 8 perk slots.

A killer who has to trigger his traps. Like a combination of Hag and Skull Merchant, imagine an electric net on the ground, but it doesn't auto trigger, the killer has to actually set it off, but it instantly deals damage and hindered.

Some of those are bad, but I tried to jot down any possibility that crossed my mind.

Massive killers

We've had Victor and now Chucky, and it would be cool to see a really big killer instead of a really small one

* Aerial reconnaissance - Twins but using some kind of bird, akin to eagle vision from assassins creed. Highlighting survivors from above and then hunting them on foot 🦅

* Tatical bombardment (effectively a mortar strike from a fps game) killer gets a map of the current realm to select a number of places to attack, like a game of battleship 📥

* Medusa - Reverse Ghostface mechanic in which survivors mustn't look at the killer, if they look too much (guage) they can get mori'd 🗿

* Abuse powered killer - Killer grows in power (movement speed, lunge, breaking speed) the more they get agitated by survivors (pallet stuns and flashlights) effectively a wind up killer who gets tilted. Survivors would have to think twice about stunning and blinding as you're powering the killer up 😡

* Survivor restriction - Ice to freeze a survivor solid 🥶 or Web 🕸 to slow, possibly even stop them (cuccoon) Webs could be used like plagues vomit, which could be used to cover gens (difficult skill checks or slow repair) or survivors can clear them (like pinhead chains) webs could also be used to cover loops, causing survivors a harsh movement speed penalty if they vault through it.
