The Only Thing that is Constant is Change By Professor Applewood

_______________Long Ago before Pokemon had a name their lived 2 deities.
_________One Responsible for "New Life" and one for "killing them" and sending them to the afterlife. _Then the humans came and saw Death as evil and Life as good, not realizing they had the same job. _____________That of moving souls from one place to another back and forth.__________________
_____This Caused a war between humans and tamed Pokemon with Zerneas and Yvetal and Wild___ _________________________________Pokemon. ________________________________________
Zerneas protected the humans by giving them food and gave their Pokemon the first Mega Evolution's __________by their bond to their Pokemon companions while not for seeing its own downfall._______
__________________Yvetal Then made Hyper Mega Evolution's. ____________________________
________________Evolution's of need a desire to strive for something. ________________________
_____________________The war ended as fast as it began._________________________________
_Eventually wild Pokemon were more and more tamed and gained more pet like features like big eyes __and bushy tails and eventually the desire they had to protect each other fell and the bond with their trainer lasted but their DNA still had the potential to do it...to become more then what they were to save ____________________________ those they cherished. ___________________________________
______________For they were never different but at the same time they were.___________________
For Every Evil their is good and for every good their is evil and their is no purity no matter how much
