It thinks highly of itself

It thinks highly of itself
Growling to nobody in particular
You can tell
The way its sitting there
Ready to pounce on nothing specific
The ground in front daring it to spring forward
It shudders and let's out a growl
Still crouched and unmoving
Bright white eyes notice nothing
A red glimmer fades
As a green star rises
The once immobile beast surges forward
The shriek and roar as it launches
It thinks highly of itself
Predator of the concrete jungle
It's rubber claws dig into paved earth
Drawing attention
Gaining on nothing ahead
But another crimson glow
To wait
Growling to nobody in particular
Thinking highly of itself
