Super Power... With a Flaw

It hurts. 

I can cure any illness. 

Granted! All you have to do is kill the person affected. Can’t suffer if you’re dead.

 uh.... what's your power?

Oops.

I can create explosives out of nothing.

They are fused to your skin and have one second until blowing up.

I can turn my arm into a giant slingshot to shoot rocks with.

Your arm is extremely sensitive and and tends to either break or get tangled, which is rather painful.

I am able to alter my genetic makeup, with me reverting back to my normal form after 4 hours.

Granted! Your normal form is now a brainless pile of slimy flesh.

i am immune to poison.

You are extremely vulnerable to fire.

I am able to alter my genetic makeup, with me reverting back to my normal form, which is a normal human, after 4 hours.

You can turn into a pink nudibranch named Leonard exclusively.

i can control bugs. Living bugs, not computer bugs.

You can do that once. Then you are normal again.

Everything I say becomes true after I say it.

You can now only say “suicide.”

i can never age and make all of my friends physically and mentally immortal too.

But your physically and mentally immortal friends all spend their time following you around and cutting your skin with kitchen knives.

I can turn stuff into cheese.

You are lactose intolerant and you can only turn the medicine stuff for it into cheese.

i can instantly diagnose any illness.

But when you do, you have the illness.

I can grind the flesh of badgers into goat cheese.

Goat cheese becomes nuclear bombs when you touch them, as well. They are activated, too.

i can drink solids.

But you still choke.

I do not exist.

The universe gives up, restarts, and you’re back again.

i can kill anything i touch at will, but only when i want to. This does not work on me.

You happen to be a psychopath that wants to murder everyone! So you are hunted by the military and killed. 

I can calculate anything math or math related perfectly and instantly, as much as I want. 

You’re a calculator with the ability to divide zeros.

i can control all machines at will, with no repercussions, and while still keeping my biological form.

You keep your biological form... In a box 9999 feet underground.

I have the power to change the weather at will.
