I don't own invader zim.
Dib lay on his bed his trench coat spread out like bat wings under him. He sighed, another day without defeating Zim and almost getting killed. He turned onto his side and wrapped his trench coat around him. He began to relive the day he had gotten it.
He had been tracking a huge surge of paranormal energy into the woods. He had been walking for hours until he had come upon a small clearing. And in the middle of it had been a large stone alter. And on the alter was a bowl, a brown crusty bowl that had held the trench coat. He had pulled it out and tried it on. The moment he had he had felt so full of energy, he had felt invincible, that he could do anything.
He had walked out of that clearing a new kid and had always done his best in everything he had done.
Dib cuddled in his trench coat, it wrapped around him like a mothers arms. He fell into a gentle sleep on his bed.
But dib had never known how that coat had been created.
Hours before he had arrived a cult had come there. They had sacrificed innocents and used the blood to call forth a devil. They had made a deal with the horrible creature that if it gave them it's wings that they would give it dead, destruction, and insanity. The demon had agreed. He had ripped off his own wings and threw them into the bowl that held the innocents blood. It had absorbed the blood and turned into a trench coat. The demon was then sent back to hell.
One by one the cultists had gone to try on the coat and each time the trench wings had wrapped around them and sucked the mental energy from them. And killed them then it had absorbed the body making the coat it self stronger.
It did this till every cultist had taken their fate. It had sat in the bowl of dried blood for hours till Dib had come to the clearing. When he put the coat on the coat had begun to drain his mental energy, but in Dibs head was an alternate dimension so the energy was endless. So the coat never ran out of energy.
When Dib would go on his adventures the coat would make sure that he lived through them. No matter how bad he was hurt the coat kept him alive.
The coat was Dibs protector; it would keep him alive forever.
It would become apart of him. Already it was beginning to become apart of his body. One day in the far future, the coat would turn back into its original state and the Dib would become a winged creature. A devil or an angel? Who knows, power is good or bad because of who uses it not where it came from.
