I am editing my modern fantasy about people with superpowers. Some of them are costumed, nicknamed vigilantes, and I need a few pseudonyms for characters who are mentioned, but never show up. I like to think of a power and base the character's name off that, so I have an idea of who they are even if they are just brought up in passing. It's been a long day and I'm out of ideas for the last two or three spots. The particular people being mentioned are 'good' but do kill criminals even when it isn't necessary. Anybody want to help?
