So, writing this as I go down the messages. Didn’t have time to thoroughly read everything due to exams.
So, Damien will obviously be neutral. As I have stated, he’s not going to attack unless attacked, case in which he’ll just resort to his usual fighting style.
Now, for every mask, a different strategy. Safe to say Damien will have no difficulty in reading any of the monster’s attacks due to his Split Perspective. Given time to adjust, of course.
The Scums are easy prey for him. Fragile and weak, they’re one Dark Smash away from dying. Plus, with Shadow Crawl, Damien can outmaneuver any of them. Over and done with.
For the Bullies, Damien would opt out the physical damage route and instead go for the psychological path. Using Distortion and Infiltrate, he’d try to evade them and force them away from the field. Assuming they are small-minded beasts, he’d have a pretty easy job to do. Maybe one of them falls of a cliff, or in a pit. Or maybe they’re going to be pumelled by a Dark Smash or a Tendril Thrash. The former, rather than the latter.
Most of the Grievers’ effects are pretty much null on Damien, and if attacked, he could use all of his Oizys abilities to evade and counterattack. Straightforward task here.
Funnily enough, same for the Manipulator. He’s already schizophrenic, what is he going to do, add more?
As for the Vainglories. They might trigger the Nightmare…Then we’ll all just pray.
And, unfortunately, I don’t see anyone that would be sufficiently fucked up for Damien to empathize with and try to help. They’re all either on the positive side or Carnage. And Carnage would try to kill Damien, then Nox would take over, then Nightmare and then we’d have Carnage on one side, Nightmare on the other, both fucking shit up for everyone. So Damien starts alone. Or, you know, as alone as he can.
