Arceus thinks he has the better of Mew, but little did he know, Mew had a little trick up his sleeve. There was only 1 oppertunity, 1 time he could gather enough strength. So Me travelled to the highest point on a planet named Earth, and waited for moonrise. As the moon appeared from behing small hills, Mew began to shine a slivery grey colour. The Arceus stood there, nearly amused by the oppertunity of finishing of Mew. The small pink creature's eyes began to open. A bright light shone from it's eyes, blinding that of Arceus. In rage and confusion, Arceus uses it's final, most powerfull attack, known to destroy planets. Arceus blasted Mew with the 1st part of Judgement. The Mew gritted it's teeth and shut it's eyes again. Mew felt her insides start to disconfigure.. Was this it, the end of Mew and all of Pokémon? The feeling inside Mew grows, but what happens next is an act of true amazement. The Mew opens it's eyes again, they still beam this white light. The Arceus throws Mew a pittyfull laugh. Then with a mighty raw, Mew throws a white, silvery light at Arceus. A bubble grows larger, and larger. It starts to fill up the Universe, pushing planets off course. Then after a high pitched noise inside the bubble, it pop's. Shards of power fly out of the bubble, crashing onto Earth. This was it. Mew lies down, and closes her eyes. The Mew turns into a small oval, simmilar to the shape Pokémon get before being born. And what happens to Arceus? 1 thing is for sure, he's not bothering this universe no more!
The bubble getting larger = Arcues' power hitting the sides, increasing mass.
Arceus is turned into an egg, which is left to the readers disgretion.
Like it? :D
