"Now, Lucas. You've constantly interfered with my plans, but you will be forgiven. After all, there will remain no spirit for all when I am done. All spirit will disappear, it will be ripped away... From You! From your Pokémon! From all those precious to you...! It is time! My dream will be my reality!"
And it almost did, my dream was practically within my grasp, until the devil came out to stop me.
Oh don't give me that look Lucas, you know what it did to me...
I ordered Dialga and Palkia to teach it not to intervene in my dreams, and what does it do?
It just breaks the red chains I used to control the legendary Pokémon, I watched as the two Gods fly away, all of these years of planning wasted.
But apparently, ruining my dreams wasn't enough to satisfy Giratina... no, it decided to take the only thing I had left, my life...
How do you think felt, watching it rip me apart, being helpless to stop it from killing me in the most gruesome and agonizing way imaginable.
But the fact is that while it was killing me... you did nothing to stop it.
I couldn't even reach for my own Pokémon before it ripped my arms off. Sure Mars and Jupiter didn't have any remaining Pokémon, sense you and the yellow hair boy defeated them. But what's your excuse Lucas? None of your Pokémon fainted, I even looked at you, I made direct eye contact with you, I begged you to save me... but you just stood there, you did nothing to stop Giratina from taking my life.
Now everyone says that it wasn't your fault, Cynthia doesn't blame you, Rowin doesn't blame you, the girl and boy don't blame you, but I blame you.
Oh how I would love to rip your intestines out and shove them down your throat, or maybe stab the broken bone of where my arm used to be through your skull, but unfortunately for me I can't physically harm you no matter what I do... but don't think that you're safe from punishment Lucas.
Unfortunately it appears that you are about to wake up from this bad dream, and escape me. But I'll be back tomorrow Lucas, and every night for the rest of your miserable life, I will haunt you with the reminder of my death.
but until then, I'll see you in Hell.
