Killer Power Idea:

The killer Power:

Stats: 110% movement speed

Terror radius: 24

Height: Tall

Killer power:

Dark Bond: Survivors hit by the Killer become marked. Survivor share the dark bond linked by the entity.

Dark form: Press activation button. Survivors that are linked by Dark Bond struck by the killer will all simultaneously share the pain of each other. Survivor who are healthy will become injured and injured survivors will become broken for the duration of dark form when hit by the killer. Survivors who are marked share a link an aura between each other and reveal their aura to the killer. During dark form, The killers movement speed is increased to 115% and terror radius is suppressed. Survivors who are marked must find a an objective(Freddy clocks) to remove the killer aura reading. When all bonds are broken, Dark form will disable. The killer must have at least two survivors marked in order to enter Dark form and stay in Dark form.

Inspiration comes from the perk Aftercare creates a link aura between two survivors. I think this could be an interesting power-up stealth killer that has setup time similar Oni but gains very powerful stealth capacity for short period of time. I am not sure what would be good artwork model for this killer, I'd recommend something like a Vampire or anything that has "Weak state" and "Strong state".
