well ive had this idea for a while... in the future, all of society is run by robots.. these robots were created by man.. the robots got so intellegent, that they deemed man inefficient and therefore must be destroyed. but there's a twist. there's a human freedom fighter in the future that survived the wrath of the robots and is the leader of an anti robot faction. he ends up destroying the robot core, winning the battle. the robots, after they lose the war, decide to send a robot back in time to kill the mother of this freedom fighter so that the core isn't destroyed by the human faction. the humans get drift of this and end up sending one of their own men back in time to protect the leaders mother... thats all i got for now, but there could be a twist, like the guy thats sent back in time and the mother make love, and the boy the mother gives birth to, is actually the freedom fighter in the future !!!
I call it, "Billy and the Robosauraus's"
