OH- sorry lol Yeah, maybe some of them do. Most of the pokemon still can go ahead with their current (Or cannon on another member of its evolution line) but some do need it if it has big design changes or an extra type or maybe just cause you want it
Dartro: While it can't fly long distances and get very high with its tiny wings, this pokemon is excellent at boosting its body forward like a dart and striking their prey while making a ear-ringing noise
It's nice in my opinion, but, I think having Team Fable actually manage to take over the region could be better. It looks like their ray thingy is really strong, so, perhaps the reason you are filling out the Pokedex is to study all those pokemon and finally put an end to Team Fable? You could...
It looks nice! I like the most things but I think it's kinda too organized.
The wild grass is too organized, kinda messing up the shapes and making them more 'wild' will improve the scene in my opinion.
The long walk in the middle is a bit plain. Perhaps put some wil grass around it? Not...
Perhaps making ice beam more restricted isn't a good idea since people could dislike it (It is used in a lot of smogon movesets or replacement for moves for more accuracy) but Blizzard makes sense. Perhaps make Blizzard's PP a little higher so it would give people a better reason to use blizzard...
Omg, I love the colors of the trees! Perhaps you could give a little garden to the house on the top left? It looks a tad too plain since it is placed a little far back and the road to it is longer than the others. It looks like it would have a front yard in my opinion. Just fences around it and...
I think 2 could be a little too overpowered, I would go with 3.
But if you want to go with something else, perhaps Libero? (Cinderace's hidden ability) It's pretty strong and I think it fits Smeargle
And Yaragi for the final one? Ya from Yagi in goat and Ragi from the Japanese translation of Holly which is Hiragi.
Sure, I kinda followed the Charmender evolution line of having all too similar names for the last two but I think they fit!
And perhaps go along with it for the rest of the evolution line? Like Amaranth is Amaransu in Japanese so you could say Amayagi which is a mix with Japanese of goat which is Yagi since the plant on its head kinda makes it look like a goat
