Human: Lets make a storyline of a short film about k-pop mutant mecha warriors vs Pulgasari (but radioactive)

Assistant: In the land of South Korea K-pop used to reign supreme. Anyone listening to other genres of music was ridiculed and even openly discriminated against. But no one had it as bad as the fans of Japanese idols. Gangs of K-pop mutant mecha warriors roamed the streets and when they found an idol fan they would be lucky to get away with just a beating. Their favorite thing to do with idol fans was to use their built-in speakers to blast K-pop at such volumes that it would rupture the idol fans' eardrums so they would never be able to hear the voice of their favorite idols again. Sometimes they would switch it up by spewing acid from their mutant bodies for the same effect.

A lone blacksmith knew that the K-pop warriors would be coming for him next. He had made a small figurine of a vaguely humanoid monster with sharp claws and pointed horns. With all of his heart he prayed to Hatsune Miku, begging her to bring his statue to life so that it may protect idol fans from their terrible persecution - and his prayer was answered. Hatsune Miku descended from the heavens and with her divine powers she brought the statue to life. She named the monster Pulgasari, the eater of iron and steel.

And Pulgasari did indeed become stronger and bigger as he consumed more and more metal. To grant him even bigger powers Hatsune Miku brought the radioactive remains of the Fukushima reactor core to Korea so that Pulgasari may feast on them. And as the radiation entered Pulgasari's body he began to mutate, growing stronger and stronger by the second. The blacksmith knew that with Pulgasari on their side the time for rebellion had come and so he rallied his fellow idol fans to finally rise up en masse.

It wasn't long until the K-pop warriors realized that something was wrong: a giant, radioactive monster was marching towards their headquarters and thousands of rebel idol fans were following it. Thanks to their mechanical bodies the K-pop warriors were able to quickly concentrate their forces and a battle of epic proportions ensued. The K-pop warriors reasoned that they would only need to take down Pulgasari and their victory would be assured, but their strategy ended up backfiring. With each felled mecha warrior that Pulgasari consumed his wounds wound close and he emerged even stronger than he had been before. Eventually the K-pop warriors realized their mistake but it was too late; Pulgasari had killed too many of them and they were being overrun.

The battle ended with a crushing defeat for the K-pop warriors and their headquarters was occupied by the idol fans. But Pulgasari's hunger for metal did not stop. He continued to feast on the corpses of the defeated mecha warriors and then went on eat any kind of metal he could find. Hatsune Miku, realizing that Pulgasari's hunger would never be satisfied, quickly hid herself in a bell just as Pulgasari was eating it. Pulgasari devoured her and as he realized what he had done he turned to stone while letting out a heart-wrenching scream. Touched by Hatsune Miku's heroic sacrifice the fans of different music genres established an uneasy peace. Whether this peace would last only time would tell but if the menace of K-pop mutant mecha warriors were to ever rear its ugly head again, then Pulgasari will be back to stop them.
