I finally came across this Legendary Pokémon as I worked to stopped Team Flare from accomplishing their questionable goals. I was tempted to use my only Master Ball I had, but I opted against that thought and instead drained Xerneas down into the red and proceeded to capture it with a Great Poké Ball. I am extremely excited I have finally come across the poster face of Pokémon X, been waiting for this encounter since I bought the game. Now that I have it, one of my other Pokémon which I am quite fond of has to be sidelined =( – ended up sidelining my Blaziken for now.
