Plan 1

Naruto brought the mask to his face as his curiosity got the better off him, along the clones who brought the respective mask to their face. As the mask touched his skin, the mask latched on to his face and a painful sensation washed over him.

The mask merged with his face, becoming actual flesh, remolding his face into of Minato, with the clones turning into Kushina and Mikoto.

His hair grew a bit, as he felt as if he were growing taller.

Naruto's body followed suit as the transformation proceeded. Muscles, bones and organs rearranged themselves as the mask was turning him into a older man. His clothes were likewise changed into Minato's clothes.

As the transformation finished, the pain finally faded away. Naruto ran to find the nearest mirror to inspect the changes.

"Amazing" He, said in Minato's voice. "It worked... I look just like dad" Naruto said with a smile. It was strange to see a smile of his father when he knows he is dead along his mother and Mikoto.
