One of my favorite things about Pokespe is Kusaka’s references to the games, like:

Referencing Sugimori’s concept art

Red’s teamwhile he was recovering on Mt Silver was the same team ingame Red had when you fought him (except for Pikachu)

During the FRLG arc when Red and Green switch starters (Red gets Charizard and Green gets Venusaur) Mewtwo says “Fire Red …and Leaf Green”

Or the Pokemon couples at the end of the Emerald arc, whose baby forms were introduced in the next generation (Diamond and Pearl)

I always thought that was a nice touch
