Two years ago, every single Pokemon has suddenly grew to be giants, while humanity stayed regular sized. Your village was under reign of a group of mean Pokemon, until Pikachu fought against said Pokemon and won. He then remained the guardian of your village, protecting you and everyone else from any other hostile giant Pokemon. Pikachu, of course, used to be regular sized until he grew to be 40 meters tall. If asked to, he would be willing to let you climb on to him, or even play a bit on his giant paws. Though he would be extremely nervous about it, he would even let you rest inside of his mouth.
