User blog:DarkBirdo/Anybody got any original emotion based Semblance ideas?

So, I'm having some trouble with my boi Frankie's semblance. I don't know what the hell to make it. I really need it to be emotion based, because it just feels right that way. My boyfriend suggested something like emotion sharing, where I guess if Frankie doesn't want to fight, he can make another person feel the same way. I came up with one that was basically discount Raven, so... I have no idea. Anybody have some suggestions?
