Riddle challenge for Fear!

So, to gain the power to "cross dimensons", you have to answer a riddle I made myself, so no cheating off the internet. You also only have three chances to guess what it is, though you can ask questions about it because it is difficult, so think hard and guess carefully. Now, here is the riddle;

Eyes like fire, large and round.
This thing will cause your world to come crashing down.
Metallic fangs, sharp and biting.
This thing can be awefully frightening.
A roar so loud, it will leave your ears ringing.
If this thing attacks you, it will leave you bleeding.

Is it a type of animal.

Nope. Not at all.

Is it a type of weapon?

Yep. Getting close to the answer.

Is it a cannon?

No.

Is it a gun?

Damn, you guessed it. Yup, it is indeed a gun. You get the power!

Question? When someone guesses the riddle and gets it right do you make a new riddle? If so, I can help because I always play riddles with my friends haha, BTW, a gun lol

Well, we don't usually do this, but a member wanted a special power so it was either answer a riddle or battle in the roleplay, but I suppose you can make a riddle for others to answer if you like.

Ok! Dis riddle is ONLY for fun! I made it up so it might suck haha!

Not the living
Nor the dead.
It really messes up your head,
It laughs and laughs
But sometimes yells,
It can be deadly,
It also kills.

What is it?Each person has three Chances to guess what it is!
