Killer Concept: The Darwin - An Evolving Killer

So as we’ve all been told, the relationship between predator and prey is an evolutionary arms race. The prey grows to become a mighty mammoth, the tiger develops giant sabre-teeth to compensate. The prey shrinks so that the teeth are a burden, and the giant fangs are lost to time. It’s circular, not linear. 

Introducing The Darwin! He evolves and adapts, but so do his prey....

Power

Evolve: When activating his power, The Darwin AND all survivors undergo changes that affect their base stats. During the transformation, the character’s body becomes a brittle husk and the new version breaks out from inside. The left-behind husk crumbles away over the next few second. (This should be a seamless transition so that a running survivor maintains speed and momentum as they break through the husk.) Characters who aren’t moving simply have their old skin crumble off around them. 

There are 4 stages of evolution and each one has a unique icon where the killer see his power/add-on info. The killer can press the active ability button to cycle through these icons and choose which stage will result from the next transformation. 

• Standard (the match starts at this phase): Basic 115% M1 Killer. All survivors are normal.
• Fast: Move at 125%. All survivors have thick hide. They take an Endurance hit first, then the 2nd hit injures them , and the 3 hit downs them. Injured survivors gain Endurance as well, and if they heal up, Endurance will remain as the first hit. 
• Strong: Move at 115%. All survivors are exposed. All survivors have haste and move at 110%. 
• Intelligent: Move at 115%. Killer can “see” all sounds (like on DBD Mobile). Generators are 1.5x as loud (both volume and range), and survivors complete generators 10% faster.

Evolve occurs when the killer activates his ability, but it has a 90 second cooldown at base. Timed right (such as during a chase), it can end chases quickly (such as switching from “Fast” to “Strong” mid-chase - thereby removing a survivor’s endurance and exposing them instead). Survivors can also also strategically evolve, as all players shift to the killer’s next selected phase whenever a generator is completed. 

Perks:

• Ice Age: As frost works it’s way up their feet, survivors must move to keep warm. Every 25/20/15 cumulative seconds that a survivor remains stationary (including healing and working gens), they they gain a token, up to 5. Tokens increasingly hinder a survivor’s movement: slightly/moderately/considerably/tremendously/immobile. Survivors may remove a token by walking for 10 seconds or running for 5 (or a combo of the two) - progress for removal remains when stopping, unless stopped long enough to gain a new token. Immobile survivors must chip out of the ice crystals for 10 seconds with skill checks before moving again. Teammates can help (5 seconds). Each additional token visually shows more frost clinging to the survivor. Survivors may come within 3 meters of a heat source (like a fire barrel) for 3 seconds to remove all tokens and prevent buildup while there. 
•  Natural Selection: The strong survive and the weak perish. Getting a hook through the shoulder is bound to weaken anybody. Survivors who are rescued during the 1st phase of sacrifice will continue to cry and whimper at 30%/40%/50% of the injured volume after they’ve been healed. Survivors who are rescued during the 2nd phase of sacrifice will continue to whimper at 80%/90%/100% of the injured volume after they’ve been healed. 
• Hex: Divergent Speciation: At the start of the match, each survivor is randomly assigned to another survivor (they must discover who their partner is). The 2 survivors in each pair may heal each other and perform cooperative actions together as normal. If they attempt these actions with a survivor from the other pair, progress is 20%/10%/0% of normal.
