Riddles...

cowardice

 

adrenaline?

 

Methamphetamine?

 

Correct Sheriff Fatman, it is fear.

New one:

In daytime I lie pooled about,
At night I cloak like a mist.
I creep inside shut boxes and
Inside your tightened fist.
You see me best when you can't see,
For I do not exist.

 

Darkness?

 

Correct, new one:

Both king and horse have this, of course,
But you'll want neither of them, perforce.

 

reign... or rein.

 

Correct, new one:

If you have it,
You want to share it.
If you share it,
You don't have it.
What is it?

 

I can't tell you the answer Gambit. It's a secret.

 

Next one then:
A man of a hundred stood out in the cold,
Exchanged his gay headdress, of colors most bold,
For one of pure ivory, just now a day old.

But though freshly dressed, the old man
stood alone - It was his misfortune to live on a wold.

 

Father Time!!!! The old man passing it to the new. (New year)

 

I think it's a tree, with the headress being the leaves. The reference to wold would then explain why he stands alone (he's in a field, not a forest).

 

Correct Sheriff, tree it is.

New one:

What is always in front of you
but cannot be seen?

 

The future?

DU, it doesn't say "cannot be seen by you." If you have a penis that cannot be seen at all, you should see someone about it.

 

Correct, future it is.

Next then:

With thieves I consort,
With the vilest, in short,
I'm quite at ease in depravity;
Yet all divines use me,
And savants can't lose me,
For I am the center of gravity.

 

The answer is the letter 'V'

 

Correct, next one:

I drive men mad
For love of me,
Easily beaten,
Never free.

 

Gold?

 

Women?
