The trailer is also on the Japanese Pokémon YouTube channel
The Japanese TV show Oha Suta has revealed a new trailer of the 20th Pokémon movie, 「劇場版ポケットモンスター キミにきめた！」 Pocket Monsters the Movie: I Choose You!. The trailer shows two different logos for the movie and several scenes remade from EP001 with the addition Ho-Oh dropping a Rainbow Wing down to Ash after which he says to Pikachu "Someday, let's go and meet that Pokémon, together!". The official Japanese Pokémon YouTube channel and the official movie website have since updated with this new trailer from Oha Suta, a second teaser trailer and new artwork. The logos, artwork and trailers can be seen in the gallery below.
