Angel has no special or supernatural powers. (At least, not here. This aint Paradigm.) Feel free to use this post to talk about general plots, though, or if you have an idea you'd like to play around with for CR.
You can also hit me up on my AIM at supergeek3751.
Threadhopping? Make certain the other mun is cool with it, but personally I love more opportunities for CR.
Backtagging? Backtagging makes RL and IRL get along without implosions.
Godmodding? Nope. If you want your character to perform an action which implies Angel has done something, PLEASE ask.
Fourthwalling? Doubt this will ever come up, but sure. The show fourthwalls itself.
Hug her? Your character is welcome to attempt it.
Kiss her? Same.
Grope her? Go ahead and attempt it, but you'd better be on her good side. And then some.
Punch/hit/etc. her? Let me know if it's going to turn into a fighty thread. But I'm completely fine with it.
Injure her? Also fine with this.
Kill her? We'll need to talk about this. I don't like plots where death is cheap, so if Angel bites it, it better be for a good reason.
Anything else? Not right now!
