I would be Progress
I would be the god of Technology and Innovation, Invention, Logic and Resourcefulness, the Power of Practical Application.
I would form the powers of Industry, The Free Market and Progress. My weapons are extremely technologically advance for my intelligence is a combination of Batman, MacGuevyer and all the backyard tinkerers you've ever known.
The Power of the Free market is my ability to create a rival edition of anything which is faster cheaper and more powerful than it's rival. It in turn improves the rival in the same way, steadily improving both.
My followers would be any man of science, engineering or of the mind to better and improve his surroundings.
My origin: I was born in fire. The first fire. Some may say you made me. As human advancement grew, so too did I. I haven't always existed. I will always exist, in some form, though. You may even know my father: Evolution, and my Mother, Necessity.
I have inhabited specific humans throughout time. Some you may have heard of, others not.
I am most proud of my child Isambard Kingdom Brunel, though you may also know of Archimedes, Leonardo Da Vinci (My first try at fully inhabiting a human, though ultimately I failed)
Others you may not have heard of are: Nicolas Tesla, Turing, Tim Berners Lee.
My most miserable failure was Edgar Allen Poe. I gave him the ideas and inspiration, yet he turned them into fabulous stories rather than the innovation that he should have had...So much potential.
I am only as powerful as you make me humanity, so strive, toil and think. You gain 25 IQ points every 50 years or so now, so I am growing ever stronger. You ISS Has pleased me. Youtube has pleased me. You incoming waves of backyard inventors because of it I have not seen since the 1800's. Grow, build and develop humanity.
Remember this. I am proud of you. You have done things that have made this god weep with joy and pride.
And lo am I sending my next great pride and joy. You will accomplish great things in the next fifty years.
Hmm...I may have gotten a little carried away, but GOD that was fun to wite *Wistful sigh*
