Den -10 is a series about a Namuh who finds the Xirtisop.


In 2055, five years after Simien left Earth to fly in space, many new heroes appear. Three aliens defend Washington from evil, called Testudo, Frigidum and Cerebral. They fight against, Ned 10, called the world's worst villain, who has the Positrix, with even a normal snail and a rock with no powers in it as aliens. But on the opposite side, things are completely different. Den is a hero there, and fights the opposites Odutset, Mudigirf and Larberec. One day, five aliens appear in a spaceship from the matter dimension. Four of them become heroes with Den, and the fifth becomes a leader of the villains. But giant cracks happen in both dimensions, bringing matter to antimatter, but why?
