Iwata enters the stage mounted on a Yoshi with wings and a shiny light. After his magnificent entrance, the Yoshi will lay an egg, inside that egg Kaz Harai will appear holding a PS4 and a Vita is his hands, Iwata will then pick up the Master Sword and will slay the PS4 and the Vita in half. Kaz confused, will try to run away just to meet Reggie in his path. Reggie holding the Samus cannon will shoot him in the face while saying "your body wasn't ready"

Reggie leaves the stage using the morph ball, leaving Iwata alone. Iwata will then transform into a giant robot and travel to the U.S and burns the Microsoft HQ, all while laughing and saying "Please Understand bitches!"

He will then travel to the moon, set up a huge screen that everyone in the world can see, and he will show a trailer for F-Zero U, Star Fox U and Pokemon MMO. Iwata will later vanish into a black hole, only to reborn 3 days later and bring peace to the world by using Pokemon is his battles. 

All this "Directly to you!".
