>>45614897Let's Go isn't part of any previous timelines.
-Red and Blue evidently don't live in Pallet Town, and their roles in the Gen 1 storyline are mostly replaced by the new protagonists and Trace, with their roles being more similar to Gen 2.
- Mina's appearance, while a cute cameo, screws with the timelines established by the prior games since we know that Gen 7 is at least 10 years after Gen 1. Mina is at most 19 in Gen 7 (since Trial Captains have to retire at age 20) so she would have to be no older than 9, and probably even younger, in order to fit the old timeline. Meanwhile her artwork in LGPE pegs her as 13-15 years old. It doesn't work out.
