Superpowers... with a flaw!

[Duck]

Granted, you can't expand back out though

I wish I could talk to animals

 

[Eleanor]

Granted, you can talk to animals, but you won't know if they're talking back~

I wish I could manipulate electric fields!

 

[Oskeo]

You will never starve! ...But you're always hungry.

I used to think a lot about this one:
What if I could hold and item in one hand and create a duplicate in the other?

edit: I was reading from the wrong page, so here's one for Eleanor:

Your powers make electromagnetic fields detectable, so cities become 5x as obnoxious

 

[Duck]

Granted, but it uses up your body mass to do the duplication. Be careful ~

What if I could fly?

 

[Eleanor]

Granted, but good luck with running like crazy to take off!

I wish I could do photosynthesis!

 

[5qwerty]

Granted, but you can't eat food anymore :(

I wish my right arm was very much stronger than my left arm and I could hold a giant sword.

 

[Eleanor]

Granted, but your left leg is now way stronger and larger than your right one to compensate.

I wish I didn't need to sleep!

 

[Devalue]

Okay. Requires eight solid hours of dancing every night instead.

Would like the power to solve any mathematical problem instantly.

 

[Eleanor]

Granted but you're my assistant now and forever. No excuses >:)

I would like to have the mind control powers that are needed to make the above actually happen ♥

 

[ReKoil]

You have them... but you lose your sense of self more and more every time you use them. After a couple days you won't be able to tell who you truly are anymore =\

I want the power to resurrect fossils.

 

[Oskeo]

It works! They can battle, grow and even eat! ...But they don't stop being fossils.

I want to be a telepathic empath.

 

[Zeostar]

Granted, but everyone you use telepathic powers on gains that power too, and it spreads like a domino effect.

I wish for better focus

 

[ReKoil]

Sure, but now you have tunnel-vision =\

I want the power to learn any language I want, whenever I want.

 

[StCooler]

Granted, and you also become an excellent developer! Oh wait, you meant "programming language", right? :)

I want the power to master any videogame in ten minutes.

 

[Megan]

Granted, but video games are now outlawed for being too violent (even those who don't do anything involving violence).

I'll take rocket flight powers!

 

[ReKoil]

You can give flight to rockets. Just swing your hammer at them!
Careful they don't explode though.

I can now detect when someone is in trouble =3

 

[moon]

Except for when you're in trouble yourself, oops.

I am now able to conjure any item!

 

[Aldo]

Except you'll need to know everything, from the molecules to the design and every little detail, about the item for it to work. Is your brain up to it?

I am now a GM in real life, and everything I speak becomes reality itself!

 

[Megan]

Doesn't help when your players all suck, though! :P

I'll take the power to conjure up more hammers!

 

[moon]

as much as i absolutely love big hammers (my DnD chars seem to favor them), the hammers don't stop coming and they don't stop coming and they don't stop coming and they oh god they don't stop coming

I gain the power of being able to put together the perfect drink every time, regardless of type of drink.
