Hiya there, everyone! It's Jolt-chan (Jolteon) here! This is my first time ever updating or making anything on this account so please bare with me! Sorry if I stink at this. 

        I remembered this theory I once saw on the Internet and thought I'd explain about it. So, what if I told you that the legendary beasts were all once a Flareon, Vaporeon, and Jolteon? Well, it's proven that it is true! Everyone remembers how the Brass Tower in Ecruteak City, Johto got burned down, right? It is believed that when the tower got burned down, a Flareon, a Vaporeon, and a Jolteon were still in the tower and perished in the fire. The three pokemon got revived by Ho-oh as the three beasts. Soon, Ho-oh left and the three pokemon wanted to thank them. They decided to all spilt up and roam Johto to find Ho-oh and thank it. (And then you go and capture them and stop their life-long dream. Wow. Great going, Trainer-san.)

       This is actually a very likely theory. Flareon, Vaporeon, and Jolteon all have the same color schemes as the three beasts and they all share the same typing! Not to mention later on, in Generation 5, the three beasts got the Dream World abilities that were Flash Fire, Water Absorb, and Volt Absorb. Aka, the same exact abilities as the first three Eeveelutions.... 

        I personally believe this theory is correct because it's proven in many different ways. It's actually really cool if you think about it! What does everyone else think about this theory? Make sure tell us! Bye now! ~Jolt-chan (@supershinypichu)
