Who Is Your Favorite M1 Killer?

So I don't want to get into a whole debate about what makes a killer an M1 killer but i'll give a quick explanation of what I use as criteria.

To me there are three types of killers.
1. M1 Killers, killers like Trapper, who can only use basic attacks
2. M2 Killers, killers like Blight, who can use special attacks
3. Hybrid killer, killers like Legion who can rely on special attack to down or injure people, but eventually have to use basic attacks to kill the whole team.

I have two main criteria that makes someone an m1 killer in my mind.
I call it my two check system.
1. If they can consistently and reliably injure/down survivors using m2/special attacks. Nurse, Blight, Billy.
If they pass check 1 you ignore check 2.
2. If they can for the most part completely ignore pallets either by attacking through them or by never needing to kick them to attack people.
This is important because I feel like Pallet Play is quintessential to M1 gameplay, killers like Hag and Spirit cannot use a special attack to injure or down people, but the nature of their attacks allow them to basically just appear at survivors than hit them. Spirit in particular is similar to Nurse in that she phases around pallets basically ignoring them, its this very instance that caused nurse to change where her powers no longer were basic attacks years ago to begin with.

For this reason I am not including Spirit on this poll but will put hag as hag at least does deal with pallets, but I personally do not consider her an M1 killer in my mind, I think she should be changed so her attacks are special attacks.

Anyway, who is your favorite M1 killer, that is the point of this poll. 😛

Any killer left off this list I either don't consider an M1 or consider a Hybrid.
