Devs, play SCP Secret lab, there are at least 3 full killer power concepts you can use for your OGs

No joking:

• Blind killer who can only see survivors moving/making sounds and can spot them through walls on huge distances- SCPs-939 (big meaty dogs).
• SCP-106 - 1) He can walk through solid objects at cost of reduces movement speed 2) He can leave a "portal" on the ground to which he can always teleport from any point of the map (like Demo's portals but only 1 and doesn't require standing on a portal) 3) Touching a survivor sends them into a pocket dimension from which survivor needs to find an exit before they die and if they succeed they are ejected on random spot on the map.
• SCP-096 - has 2 states - Docile&Angry. Emits loud crying that alerts survivors of his location. In Docile state he moves slow and is able to temporally make himself quieter and he is able to see all survivors. If he's being looked at, enters Angry state after a ~5-7 seconds period during which he remains still on place and emits loud alerting sound. When angry, he has killer-instinct-like revealing mechanic that allows him to see survivors that looked at him and is unable to see any survivors that hasn't looked at him. Anger state duration is increased for every survivor that has seen SCP-096 and more survivors can be added to his "hitlist" after he's entered Anger state. He also has access to an ability that allows him to make a long leap forward, cutting distance between him and his targets.

Just adapt these a little to suit the game even more and you'll get 3 killers with unique mechanics. You don't even need to get any rights or anything, just use these as basics for creating "inspired" characters.

These powers wouldn’t work at all in game like dbd and some of them are already incorporated in some shape or form. SCP-939 blind but can see moving survivors but has wall hacks of a survivor is doing something from far away since they are moving or when they are in chase they have perma wall hacks sounds like old Freddy but with less steps. SCP- 106 in your own words kinda like demo with the portals, the going through walls kinda like nurse, and the pocket dimensions is too complex and game changing to happen especially if it’s to follow the lore of SCP- 106. SCP-096’s power just sounds like a worse legion with demo’s lunge attack. While I think these powers suit well within the SCP universe it would not benefit new killers as it’s ether too complex or already within in the game in some shape or form.

Hell yeah, I'd love a blind killer and shoving people inside 106's pocket dimension sounds great.
