I am

I am a crown
I float on air
in the blue sky around
I am a bear
My coat is eternally brown
That I always wear
I am a noun
Choose me with care
because I have found
good ones are rare

I am a spider
with too many eyes
Because I fear liars
and fear I despise
I am a fire
I burn with her cries
reflecting celestial choir
I am wise
and I never tire
 as butterfly's fly
that I can admire

I am dragon
slinking under the light
petting my own talon
I am right
not a misshapen
or bruise in sight
I am an assassin
Always up for a fight
In the midst of the action
Killing isn't my only plight
