Say there is a super villain named ... something dumb, like Isotope. and he is powered by a radioactive core, this core gives him power to shoot energy blasts, but also to power different devices added to his combat armor, like rocket boots, or sonic blasters, making him as dangerous as what ever piece of tech he can steal.
now the hero is a real piece of work, a guy named something equally as dumb, like Omega Man.
Omega Man is loved by all the Earth, and is the defender of Truth and Freedom and all that. but is real life he is kind of a jerk, and loves whopping up on the bad guys. sometimes he will let them beat up on him in public, so he is justified in giving them a extra long smack down. he verbally abuses them when no one is around to hear him, and he has been known to use threats to keep cretin people in line. but he works the media and people love him.
Omega Man has had a wonderful career starting as Omega Lad, then Boy, then Omega Guy when he was in collage, and finally Man. he was pondering becoming Captain Omega when he became aware that there was a decline in good super villainy. he was basically down to two heavy hitters, Isotope and Master Invader. Master Invader comes from space and you never know when he was going to show up, so Omega Man decided that Isotope could not make it to prison ever again until someone new came along. after a few years Isotope began to suspect something, and looked into it.
Omega Man was indeed the reason for many of his escapes. what Omega Man never knew is that Isotope had stopped working alone a long time before. he had paired himself with another super villain who was no longer able to fight. Viral was a cyber villain who had lost corporeal form in a battle with Omega Man, now he lived in computer systems and gave tech support to other villains. Viral had been tracking the oddities in Omega Man and had found that he had lined up a way each time Isotope fought him to let him escape.
Isotope had of course been enjoying being the big baddie on the block for a few years, but this news robbed him of any joy. together the derived a plan to get all the other villains free and make Omega Man look like a smuck. on their latest fight Isotope takes a beating and then instead of escape, surrenders, publicly to Omega Man. Omega Man is forced to accept the surrender with the world watching. Isotope is tried and convicted in a world court and sent to the hidden super villain prison of Alpha 12. his core is powered down just to the point to keep him alive, about the radioactive level of a cell phone. and he is loaded into a van made special for him. it is a lead armored car. and though the car can keep radioactivity out, it can not block the tracker that viral had on Isotope. he tracks the signal as it takes him to the hidden prison where he is supposed to launch a rocket attack and get Isotope and all the other villains out. but Viral is a villain in his own right and has decided to launch a nuclear missile instead of regular ones. see he has built a new techno body for himself and is ready to take his place as top villain.
This is how it goes down, nuke launched as lead van approaches prison, omega Man swoops into stop is, but is conflicted, isn't this what he wanted, an escape. he hesitates and stops the missile too late and it explodes just above the prison. this throws the lead van tumbling off the road and berried in debris, and the prison exposed, villains poring out of it. Omega Man is missing, Nukes hurt after all, and a worried world decides he has fallen and worried about a gang of super villains sweeping the country side decide that since a nuke has already hit that area, another one should be OK. so 12 hours later they hit the prison again. 85 % of the villains are killed. the other 15% had already escaped or were nuclear powered already. this starts the Radiation Wars, a decade long struggle between the remaining heroes and the now over powered radiated villains. the war leaves most of the world irradiated and ravished, while the most people live in walled off city states that claim to be open Utopias.
Isotope remains in his prison Van, blocked off from the world, basically shutdown, until some scavengers pick up his tracking signal he left for Viral, 80 years later. there is a new race of humanity, known as scavengers or Radio Heads. they have adapted to live with a cretin amount of background radiation and can live in fallout areas. they scavenge the areas looking for useful items. and as the dig out the prison van and crack it's lead seal radiation floods in. radiation enough to jump start Isotopes core.
this is where the song takes place, as he starts back up and gets his first glimpse of the new world.
he learns of the Radiation Wars and how they were won. it turns out that Omega Man was a bit of a flirt and had had children all across the planet. he had left messages for them when their powers manifested and called them all to be super heroes. it wasn't until the Omega Brood started showing up that the villains lost the war. now they have divided up the world and each look over a different city state. and they decided who gets in and who lives in the wastelands.
Isotope is the worlds only remaining super villain in a world ruled over by the children of his Nemesis. A world unfairly ruled. he picks up the mantle of the Scavengers and speaks to them of revolution, and starts his march to the nearest city state.
All that is in the song, you just don't hear it, I do.
