I've been trying to write a TF fic for a while and I just haven't had any luck. But I did think of something recently. I wanted to do a TF origina besides Quintesson slaves, or Primus created. I've seen the naturally evolved origin in Marvel's first issue and found it very funny and I've never liked the idea that current TF's ancestors might've been organic and then put themselves in metal bodies. So I thought of this. There's a planet that develops a civilization, millions of years ago. But they manage to wipe themselves out through warfare. Their machines surivive though. They repair the planet, and themselves and over time they continue building. When they realize a certain repair would be best done by something with thumbs they build a hand with a thumb. And as they need more factories to build more machine they build them until the planet is nothing but machinary. And finally one day one of the robots it builds becomes self-aware.
