The trailers for Pokemon: Detective Pikachu feature a fiery battle between Charizard and Pikachu, although it doesn’t go down like anyone would have expected. Charizard busts out of the gate, rage in its eyes, ready to Flamethrower little Detective Pikachu into smoldering oblivion. This Pikachu, however, isn’t like other Pokemon. He’s not only a detective, but he has the mysterious gift to speak with one human in particular, protagonist Tim Goodman. As we see in the trailer, this Pikachu was made for solving cases (and drinking coffee), not battling. In fact, he doesn’t even know how to use his moves, leading to a comedic beat about performance anxiety courtesy of Ryan Reynolds, the voice behind our fuzzy yellow private eye.
