The definition of a monster is subjective.
The dictionary understanding of a monster is something inhuman. However, the variety of monsters, fictional and real, is so complex and deep that the simple dictionary definition becomes obsolete almost immediately. There is only one known way to organize 'monsters' as a whole, dividing them into three categories.
There are what are called 'Pocket Monsters'. Pokemon, for short. Creatures wielding the very elements and using them for powerful combat, and yet can be tamed. Befriended. Commanded. By children, no less.
Children such as Ash Ketchum. He is young. Brave. Inexperienced, by the standards of many. In truth, however, he has seen far more than any of his rivals could dream. He has ridden on the back of legends, fought with the gods themselves, and triumphed over impossible adversity. And he is still but a child.
The second class of monster is 'human monsters'. Those draped in the skin of men, but with blackest hearts, eager to pervert the laws of nature and endanger the innocent for their own gain. Some could argue that these are more deserving of the title 'monsters' that the Pokemon.
And then…there are the murderous creatures of the darkness, inspired by the most horrific nightmares. Brutal abominations, their sole purpose: to torment.
The monsters of my home.
Sharing a world, and yet worlds apart, from the trained monsters of Ash Ketchum and his companions. They are innocent of the monsters of my realm, knowing nothing of them. They are content to journey alongside their trusted Pokemon, in a grand adventure.
And yet, one must wonder.
Should this child, this brave impetuous youth, stumble into my world, a world of nightmarish monsters and violent redemption, what would become of him?
Would he lose his mind? Be overcome by horror and succumb to madness, as many would? Tear out his eyes, trying to block out the brutality of his hellish surroundings?
Or would he feel right at home?
