Here is a question if the DLC introduced some more cross gen evolutions which Pokémon would you like to see get one?
Off the top of my head these ones spring to mind but this is more hope than expectation
Parasect- Parasect is one of those designs that I like but its typing and stats can hold it back (while it was useful for me in LA that was due to LA being a bit unique it would be hard to use in a more conventional game)
Ledian- As its current stats really don't suit some of its abilities (e.g Iron fist with base 35 attack) meaning its hard to use.
Dewgong- Has always been in the shadow of other water and ice types- could do with something to allow it to differentiate
Arbok- Is a cool design but statwise it struggles
Any spider Pokemon- Pretty much all of them could do with a boost. Not Picky as to which.
Barbaracle- Has a unique design which I think could be very interesting to get an evolved form
Gourgeist/Trevenant- Think their designs could be expanded in a interesting way
Gogoat- always felt like they could do something with this one and given that Geeta uses one it seems like a good choice to get an upgrade
Heliolisk- Never felt like a final stage to me even if I do think its cool
Any Pokemon that has a regional form which has an evolution but does not have an evolution itself (e.g Kantonian Farfetch'd)
Raifort is my favourite teacher because of how suspicious she seems and I would love for it to be followed up on in some way. But I don't expect any of the main game characters to play a significant role in the DLC.
Its one of those I could see either way. They've definitely set it up so she could be but it could easily just be that they wanted to make her a more fun character by giving her suspicious traits even if they don't intend to follow it up.
