Kanto:

.A Native American themed cubone and Marowack, I’m picturing paint on their skulls with feathers attached.

.A male version of Jynx

.A tumbleweed tangela that evolves into a dust storm entity instead of tangrowth

.This may be a reach but, a white Zapdos so the bird trio is made up of red white and blue.

Johto:

.A cute snubble line. Snubble would resemble a golden retriever puppy and granbull would be a larger cuter golden retriever looking Pokémon.

.A sudowoodo that resembles a redwood. I’m picturing it tall like alolan exeggutor.

.Maybe unknown that resembles Native American symbols?

Hoenn:

.A rattle snake seviper and coyote zangoose.

.Fuck it. Red, white, and blue, keckleon.

Sinnoh:

.A Unovan Bronzong that represents the liberty bell, and bronzor representing a penny.

.A water/grass carnivine that represents a mangrove tree (carnigrove?)

.A lumberjack themed snover and abomasnow would be a cool representation of Canada as well.

Kalos:

.A clauncher and clawitzer that resemble Atlantic lobster

.Hawlucha with resemblance to Hulk Hogan, bandana and all.

Alola:

.A yungoos with an orange face and a gumshoos with an orange face, smaller hands, and marking on its torso that resembles a tie.
