Grass-type Starter Pokemon:
I wanted to create a trio of Starters whose common theme would be “the monsters of cinema”.
For the Grass type, I chose to represent Aliens and other extraterrestrials, which are very present in pop culture!
As a model, I obviously based myself on the Xenomorphs from the "Alien" movies, but I also did some design research to use the Aliens from "The War of the Worlds", "Independence Day" and the "Arachnids" of "Starship Troopers".
For the theme specific to the Grass Starter, namely the theme of "extinct or ancient animals", I based myself on the order of Zygentoma, a group of flightless insects, extremely ancient, appeared long before the dinosaurs or the first winged insects and which still exists today!
And to link them to their Grass type, I based myself on thorny plants such as Brambles, Roses, Holly, Gorse, etc. I made this choice because I find that these plants are under-exploited in the Pokémon license and also, because I like the ingenuity of its plants to create their defense systems while optimizing it so that it does not interfere with their photosynthesis or their reproduction.
The Shiny was not easy to design, although I already had my idea of "Malachite Green" for the final evo... the other shapes seemed to me more difficult to imagine, and it was ultimately based on the Shiny of a Bug/Grass Pokémon, that I was able to create a chromatic color which is not necessarily pretty, but which fits with the concept of "Shiny more interesting while evolving".
