Legendary Beast Theory

There has been a debate about how the legendary beast were created, and today I will explain it to you. There were once three eeves, unevolved and trying to find out how to evolve. One day they encountered Ho-Oh, the legendary fire bird pokemon and he gave them the gift of evolution. When he was making them evolve, he gave them too much power, an overdose, and they ended up transforming into something more, the legendary beast.
