My name is Darkrai's nightmare because I have a group at school with 4 of my friends. We are always competing to see who is king and who wasn't. I was always second place, my friend Riley was always beating me with his Dialga (later on I found out he was secretly using the action replay, even though nobody else in the group was). When Darkrai was first announced, it was love at first sight, figurativley speaking. I went to the event to get it and I trained it non-stop secretly. All of my other friends were to lazy to go the event, and they did not really care about Darkrai. For some strange reason, they did not like him. Anyways, on our trip to Astrocamp, I challenged Riley with my new Darkrai as my secret weapon. I won fast, it was easy with a Darkrai that knows Dark Void, Dark Pulse, Roar of Time, and Spacial Rend. I became king and I stayed king for the rest of the year. My friend called battling me a nightmare, and there we go, Darkrai's Nightmare (since I was called a nightmare due to my Darkrai). Also because Darkrai inflicts nightmares.
