>>42835567BW isn't the start of anything. It is like that awkward final episode of an anime that is just there, without any relationship whatsoever with previous episodes outside of being in the same universe. The audience isn't really meant to give it much thought, its only purpose is to let them know the anime is over.
>They are fakemon tier takes on the OG 151Funny you would mention that. A final episode sometimes will feature expies like reincarnations, great-grandchildren or just people imitating/taking the mantle of the protagonists.
