I see a lot of gen 1 Pokémon in the valordex are listed in the Info Hub, but I can't find that forum section.
The section could have been renamed since the last update of the dex, News Desk or Support Hub may be that one, don't take my word 100% on it tho is been a long time since we had a place called Info Hub I believe.
I have a suspicion that it might be this place we're posting in, because I've seen a lot more gen 1 mons here.
@JaredNC Yup sorry, we actually renamed as Hrae mentioned. Info Hub is now both News Desk and the Support Hub so you should see Gen 1 mons around there!
I think that section was also renamed, it should be the "Pokèmon Catcher" section now, if I'm not mistaken.
