That's still something I'm working on as angels (even the lowest) are incredibly powerful, so there's a lot to think of in terms of power. I'd say Shapeshifting definitely (to blend in mainly) but the rest?

I have no idea.

And then there's the fact that angels (both in my headcannon and the Bible) can't be killed by anything but God...I guess I could do an Absolute Immortality type thing where he comes back after a certain amount of time or something.
