Tonight, I ran an adventure titled "The Secret Origin of Mechanon" because I'm not a fan of the one in Book of the Machine and my world has a weird history, but it's not Champions without Mechanon. Some very special quotes are below. Due to a character named El Caminante creating a Klein Bottle in a temporal echo zone, my entire game almost became "Mechanon and the Mecha Men."
Basically, Mechanon was "created" when an American satellite named the N1-MK1 crashed in Africa after falling through a radiation belt. The "camera" and recording apparatus/computer was the source of Mechanon's origin. However, this created a quantum "echo" that wouldn't appear until present day. In 1957, the Americans and Russians sent superteams to retrieve the key data from the satellite. The Americans retrieved what they believed was the key information, but one of the russians secretly palmed the operational (irradiated) core and brought it back to Russia. He didn't even tell his fellow team members. Over time, mechanon built itself and began it's plans.
So the Quantum echo occurs. The russians go to investigate. The PC's team hears of the echo and goes to investigate. Well...Mechanon, sensing a familiar signal without really understanding it, shows up.
So they fiddle around with the Quantum echo for a while and accidentally displace themselves a couple times, only El Caminante decides to use his MOBIUS FIELD power to teleport inside the Quantum Echo. Well, he successfully reached the center. Unfortunately, all he got out before Mechanon shot him in the face and kayoed him in a single shot was "Mechanon! AAAAAAAAAAAAAAAAA!"
So the Russians and the PC's (after a brief explanation) fight Mechanon. And Mechanon isn't just winning. He's demolishing them. So El Caminante decides to put Mechanon in a Klein Bottle. (Yes. Inside the Quantum Echo. Clearly this is a great idea!)
Augenblick: DON'T DO IT! OOC: Do you really want to be the subject of the "I can't believe my players did this really stupid thing last night story?"
Me: OOC: No, this is more like you saying the same thing you said to Ryan in Mind over Matter. "I've done some pretty dumb things in Mike's game over the years, but this one has them all beat!"
Mechanon: You are the most dangerous one here! DIE!
Players (Except El Caminante): WE AGREE WITH MECHANON!
El Caminante misses. A Klein Bottle hangs oddly next to Mechanon.
Dr. Pranava's Player: I have never wanted a player to miss a villain so much! Oh my god!
(Game stops with laughter for five minutes here)
So Augenblick teleports the satellite into the path of Mechanon's attack. The satellite explodes, demolishing the Klein Bottle. The quantum backlash destroys Mechanon, who screams "NOOOOOOOOOO!" as he falls to the ground as a limp heap of parts.
