So Who TF Are We Exactly Playing in Pokemon Let's Go?

     The recent trailer for Pokemon Let's Go was released and at first it seems to be nothing big as you finally get to see the other Gym Leaders and the Elite Four and how their battles will be.

     However in the final part of the trailer, it is said that you'll will meet other characters. What other characters you say? Pre-Gold and Silver Jhoto Gym Leaders? Nope. As a total shock you get to meet and battle Red, Blue, and Green from the original games. This seems to be huge but as big and exciting this news may be it leaves a lot of confusion and leaves a big question: Who exactly are we playing in this remake?

     For those who don't know Pokemon Let's Go is an enhanced remake of Pokemon Yellow, which was a gen one game.With most remakes it implied that you are playing the same character as the original. At first you would figure that would be the case in Pokemon Let's Go, but yet here we are encountering not only the main character of the original game (Red), but we are fighting him and his rivals (Blue and Green). So, who are we exactly playing as if we're not playing?

     So, what gives? Recently Pokemon has been more sci-fi with us lately with the introduction of wormholes and possible alternate realities and universes. This was lightly touched upon in Omega Sapphire and Ruby where a NCP stated that there is a possibility that the remakes could all be set in an entire universe instead of them just being retellings. This was later brought to the fore front with Sun and Moon where wormholes played a crucial part in the game and elaborated even further in Ultra Sun and Moon where Giovanni actually went in some of these wormholes and alternate universes to start his new Rainbow Rocket empire. Are the characters we are playing in Pokemon Let's Go are alternate characters in that universe and had the original Red, Green, and Blue somehow been brought in that universe via a wormhole? If that is the case this could be the first time in the series where former main characters meet their alternate universe counterparts. Or this could be so weird non-canon post game battle frontier thing some they always do in a couple of games. What do you think?
