Backstory: Existing upon a planetoid which lay hidden away within Earths atmosphere ruled King Tassel, the ruler of his alien species, the Rykornians. A race of geometric corn peope, the Rykornians were born from giant stalks of rykorn which could grow was big as redwoods overnight and in the process sap decades of nutrients from the surrounding soil to accomplish this. The Rykorn itself utterly lacking in any nutritional value, this made the Rykorn and its associated Rykornian people a vile paraside which sought to steal the life of planets, giving nothing back in turn.
The planet Rykornia from which the Rykornians dwelled was at one point a rich and fertile world with a wide and diverse ecosystem. However the Rykorn and its progeny the Rykornians quickly spread and consumed. Leeching all other life until the world was nothing but pure Rykorn and the Rykornians.
King Tassel the ruler of the Rykornians saw their world which was covered in vast forests of rykorn and wept for there was nothing more to conquer. With no more space for his people to grow and consume, King Tassel set his sights on Earth and its bountiful resources. Dreaming of the Earth with every living thing on it reduced to feed for the giant stalks of Rykorn. Every other plant choked to death by the invasive species.
Thus King Tassel plotted and schemed to invade the Earth! Enslaving humanity to aid in their planets inevitable demise at the hands of their new Rykornian overlords!
