I was shocked that after I beat the Elite Four fifty times in a row with only Pikachu, I was challenged to battle by Mewthree! It was pretty twisted.
What actually surprised me in Pokemon, though, would be:
~ Lavender Town. I was spooked by those ghosts when I was really little. I had Yellow, and I only used Nidoking. For my mighty Nidoking to be afraid of these ghosts shattered me. My Nidoking was not ever stopped, not since the day I realized that I couldn't use Pikachu to defeat Brock.
~ Shiny Pokemon. My friend and I played Ruby (I asked him to get Sapphire so that we could have all the Pokemon, but he got Ruby anyway because he thought red was a cooler color) and one day, he called me over to see his green Taillow. He traded it to me so I could check it out. What I thought happened was a glitch, but I understood that it wasn't when I saw the stars come from it. Someone programmed that.
~ Pretty much every champion. Gary I kinda saw coming. Steven was the next champ I fought in my life, and I thought it would be May. Next was Cynthia, and I thought it would be Barry. In Crystal, I was expecting that Suicune guy to be it, but no, it was Lance. White surprised me with N, and then X surprised me with that actor lady. I'm no good at predicting the champ, I suppose.
~ The Regis. I was reading one of those GameFAQs posts that I didn't believe. It was about the Regis, and for once, I decided I would check it out. I got the Wailord and Relicanth, and dang. They did exist. I was just as shocked when I got myself to import my Regis that I treasured over to my Diamond cart to get Regigigas.
~ Smogon? Online simulators? Marriland isn't the world champion? Cripes, this is bigger than I would have expected.
