Welp, I got... "Fairy Aura" ... I can "coat [myself] in fairy essence allowing [me] to give off an aura of beautiful energy and joyful power towards [my] opponent. This power can be used to expel certain attacks and fill an opponent or [my]self with happiness and bliss simultaneously during a battle."
Behold, I am now the mighty... UselessMan! Oh well, at least I can use my power to stop feeling sorry for myself. *Hyperactive voice* OOH, outside of combat this power would be AWESOME. Nobody has bad days around me. I can stop people from jumping off roofs. I'd be the best at parties! I'm gonna have SO MANY FRIENDS! ITS GONNA BE AWESOME! */hyperactive voice*
I'm gonna do a few more for lulz.
Firestorm Creation: The power to create a terrifying inferno that incinerates all. Basically, no control, once I've activated it. Everything in the area dies. I am... The Nuclear Deterrent! Stopping evildoers dead in their tracks with the mere THREAT of using my powers... But am I actually willing to?
Additional Limbs: The ability to grow or posses additional limbs. Apparently, this includes growing elemental, entity(i.e. ANY CREATURE, magical or otherwise), and mechanical limbs, regenerating lost limbs, and even the ability to grow EXTRA HEADS. Not sure how a head is a limb, but I'm not complaining. I'll call myself Mistwraith, after the creature with vaguely similar abilities, as well as to confuse any enemies who haven't read Mistborn. Oh, you expected me to turn into fog? Well, I just grew four extra arms ending in GIANT FLAMING PREYING MANTIS SCYTHES.
Sin Manipulation: Sounds sinister, but I can increase or decrease vices, which would allow me to help people overcome addictions to gambling or pornography, by shrinking the vice into oblivion. I am... a therapist. That is literally my superhero name. Not even The Therapist. I shrank my ego too much for that. I could stop most crimes by removing any selfish motive, or force a criminal or corrupt official too clever to be caught to get so greedy as to make a mistake.
Nether Manipulation. NETHER MANIPULATION. Highlights of the "Applications" Section of this article include controlling the elemental forces of the underworld, RULING the underworld, controlling natural distasters, Cosmic Manipulation, Astral Manipulation, Necromancy, and CONCEPT DESTRUCTION.
I am become death. I have no name. I need no name. All shall love me and despair. Unless I decide to destroy all sadness forever. I should probably do that. Also, I can reshape the afterlife into a steampunk island resort if I feel like it.
Ray/Beam manipulation. Any light nearby? Well, it's now a laser EXPLODING YOUR HEAD. Good, clean, simple fun for the whole family. Never need sunscreen, those UV rays BOUNCE OFF ME if I want them to. Also, I can control electricity with this power, so I can throw lightning at you. I need a source for these rays, but electricity is almost everywhere, and I can keep a bandolier full of batteries in the event of a blackout. Apparently, I can control magnetic rays and beams, but I've only ever heard of magnetic FIELDS, so I'm not sure exactly what I can do with that. I shall be... Scotty, because if you mess with me, I'll beam you up.
Pain Constructs. I honestly don't know if I have to use my own pain for this. If I don't, as I fight my enemies, with each new wound I inflict, I gain more constructs. Either way, if you cut off my arm, I'll use the pain to make a cybernetic limb. I should probably carry a cattle prod or some other zappy thing with which to cause myself pain without injury to fuel this power, but as I get better with it, I can probably fuel whatever I need using only my chronic back pain and frequent migraines. I shall be... THE PAINter, because I use pain to create.
Boneless Body: I have no bones, and am highly flexible, but can still maintain a human shape and move like normal. If I have a skeleton, It's made of cartilage. Basically a less OP Mr Fantastic, So I'll be... Mr. Pretty Good.
Corruption Blast: If my attacks don't kill you, they'll leave you cursed, I think. The ability to "release corruptive or malefic energy or substances on a specific target area is a bit vague. We talking curses? Unnaturally strong acid? Whichever I want at the time? I suppose melting anything in a given area is pretty useful. Could bring down a building if I got the supports, or destroy tough armor with a less powerful blast. Melt your gun if I don't want to kill you. Making an attack that small and targeted would take a lot of practice though, if it's even possible. I am... L33t H3x0r.
Mental Shield Penetration: I guess I'll find a telepath and be their sidekick, since there's no point in breaking a mental shield if you can't read minds. I'm not giving this a name. The sidekick doesn't pick their name, as far as I know.
Fate Immunity: Pretty much what it says on the tin. I will never be ill-affected by coincidence. The fact that bad things only ever happen to me on purpose, however, drives me to a level of paranoid insanity never before seen. I am... the Free Hate Movement. It's a movement of one. I fired my secretary because she kept poisoning my food. I never let her touch my food, BUT SHE WAS POISONING IT ANYWAY. I SEE YOU OVER THERE. GLARING AT ME. I'M NOT CRAZY!
Paint Manipulation: "The ability to manipulate paint/pigment and make the paintings real." Also, I can enter paintings. Also, since I can CREATE paint, I can literally summon a perfect painting of anything I want. and then make it real. So I can basically summon anything I can imagine. This might be my favorite one yet, I can make anything I want, be friends with fictional characters (by summoning them to my world OR entering theirs, as I see fit) and even... BE GOOD AT ART *Gasp.* Let's be honest, I don't need a superhero name for this. I'd just hop into the world of Doctor Who and be Clara's new sidekick, the position's open now that The Doctor quit

If I painted food, would it be edible, or still made of paint? Hmm...
That's all for now, But I do plan to come back to this thread. 'Tis good fun.
