The second trailer for Pokemon: Detective Pikachu offers a much better idea of the plot and features the live-action debut of the OG Legendary, Mewtwo. We’re going to break down the new information we learned and see how the powerful Psychic-type fits into all of this.
Here’s the new trailer if you want to give it a look:
Pikachu tells Tim Goodman that he woke up with amnesia and the only clue he had was the tag in his cap saying it belongs to Tim’s father, Detective Harry Goodman. It looks like an attempt was made on Harry’s life, perhaps because he was investigating the case of the missing Pokemon we see posters for and discovered it was linked to a larger conspiracy. So now it’s up to Tim and Pikachu to get to the bottom of it, with some help from their young reporter friend Lucy and her Psyduck.
