ROBOTIC RAMPAGES – Time Travel
You thought you had the robotic army defeated. You smashed their defense grid, blew up the main base, and destroyed the robot boss in a huge and elaborate battle sequence. Nothing else to worry about, right? We regret to inform you this is not the case.
Robots have an extremely annoying tendency to send themselves back in time. They usually wait until the freedom fighters are just upon them, and then open a temporal gate to fifty years in the past. This gives the mechanoids plenty of time to change events and make sure the attack never occurred in the first place. They might do this by killing the mother of an important rebel leader, forcing certain technologies to be developed earlier, or just messing around with the stock market. It’s worse than cheating – no surprise that a robot would think it up.
There is some danger of paradox. If the robots kill the person that invented them, they’ll disappear in a puff of smoke. They’re usually careful about such things, though, and constantly scan history books to prevent overlap. The robot’s builder may even gain a new source of funding from a mysterious and metallic-voiced benefactor. You probably won’t know that any of this is going on, but there may be clues – keep an eye out for people with the same name being murdered. It might just be coincidence, but a time-traveling robot could also be on the loose.

It most likely that the robot can travel, But you probably built it when you were traveling looking for your other paired traveler, that you need to travel, not just things, they must be pairs .
