Nightmare Fuel: Pacificators
Shiva burned one of the Romanian sleuths alive.
The other Romanian sleuth threatened Daryl’s life, and just when everybody thought he was going to stab her, he stabbed himself and allowed himself to fall into the ocean to be eaten alive by sharks. (Doubles as Fridge Brilliance and Shown Their Work - sharks are attracted by the scent of blood.)
When Cinna gets angry, she gets angry.
Yuma hit Qamra with an Orange Type 3 bomb, causing her to lose an eye and an ear. The damage was so bad, the eyepatch now covers the entire left half of Qamra’s face.
Nozomi used her powers to save Queen Belinda from the assassins... via Body Horror attacks: tearing one assassin's heart in half, suffocating another by sucking the air out of his lungs, and bursting another's testicles.
Apparently, when Benito first met Nozomi, he quickly learned to respect, and fear, her after she destroyed one of his testicles.
Remember how a lot of non-powered people seem to dislike those with powers? Apparently, we have CastellaBrandsford to thank for it - she was once one of the best Pacificators of Light they ever had, and then she went mad…
