Meanwhile, after Ness defeated Giygas 3 years ago, he only managed to banish him to the 75th dimension. Giygas's small ammount of remaining power on Earth has awakened him...

Giygas: Wh...where am I? What happened? What's this? My mind has returned!. Pokey, you fool! Calling me an all mighty idiot! My mind was not destroyed by my power, and I have awakened. I sense... a slight amount of my power on Earth. If I can use my ghostly form to connect myself with that power, I may be able to return to Earth. WAHAHAAHAHAHAHAHA! YES! I will have my vengence for my humiliating defeat at the hands of Ness! Now that my mind is restored, I will be able to show Ness my true form that only Pokey knows, then, I will force Pokey to return to my side! It has been ten thousand years since I was banished here by Ness in the Cave of the Past. I shall see you again soon, Ness. Very soon.
