I once had enemies!
Then I took on the utmost pinnacle of Pulchritude and won them over with my sheer charisma and charm.
Now that you've had fun imagining that farce, I instead just did some research on them then ruthlessly annihilated them with the help of some buddies. I was just lucky, really!
Ultimately, when it comes to enemies, I make it my policy not to fire the first shot, that way if they decide to make their problems my problems, I can feel validated in annihilating them if no other option is given.
I do my best to avoid that outcome, though!
