megalomaniac 

My Definition is a belief is so strong that I am so powerful even more powerful than god
I am paronaid of all things and make sure all my phones are not tapped
I say bring it on to take over the world
Any one standing in my way is un patrotic

I am to powerful for my boots
Bring it on we can take the world
I hear voices
You know I am god and he made me do it
