Adding to my non-Harry Potter verses page...
X-Men: My Power?Feels.He’d always been good with people. His habit of speaking his mind at inopportune moments does get him in trouble. He was born in Elstree a place a few miles from London, but grew up in the larger city. He is an empath. He has the ability to sense, interpret the emotions and feelings of others and emotional residue left on objects. He can also manipulate them. Off-shoots of this power are telempathy, the ability to send his own emotions to others and pain manipulation, the ability to manipulate levels of pain. This means he can relieve or heighten feeling physical or emotional pain.
How He Discovered His Powers:
Angie, the girl he fancied for ages, changed her mind about just being friends.She broke up with her boyfriend and confessed her feelings to Lee. After a couple of days, he was curious and asked why. She wasn't able to give any reason beyond "when I'm with you, it feels right." Something was off. And he could tell she was just as confused even if her words were sincere. On a hunch,he called her when she was at home and asked a simple question:
"How do you feel towards me right now?Be honest.Do you love me?"
"You should talk to your ex and work it out."
The next day, Angie's ex confronted him and said it wasn't fair for him to toy with her heart, then, completely avoid her. The Ex's fury a,Lee's own jealousy and indignation that he would hurt Angie on purpose and a single,childish thought-- I want you to hurt--dropped the Ex to the floor in agony.
He didn't know how or why, but he knew somehow he had made it happen.Horrified, Lee fled. If he ran far enough, that would break the connection, wouldn't it?
His own emotional state can affect his ability to block other's emotions from overwhelming him or vice versa.
Other's high emotional states or feelings of physical pain can affect him.
If his powers are blocked by say, a telepath it's surreal for him and makes him feel lonely because that sense of connectedness with other people is cut off.
It's not a good idea to get him drunk.Sure, he's usually a happy drunk and at a certain point everyone will have a sense of euphoria, but do you want to deal with him unintentionally projecting his nausea and regret in the morning? Probably not.
