Ok, so I'm sure everyone knows the whole "Fire Starters=Chinese Zodiac" thing, but I don't think I've seen anyone address this particular idea I theorized back in Generation 3.
The Grass Starters are all prehistoric animals, chronologically across the ages.
Veunusaur= early amphibians/ dog-like reptiles/ Triassic Era
Meganium= Sauropod/ Early Jurassic Era
Sceptile= Therapod/ Late Jurassic Era
Torterra= Ankylosauria/ Cretaceous Era
Serperior= snake, first appeared in Mid/ Late Cretaceous
therefore, I predict that:
Chespin Final=?= Glyptodon or Giant Armadillo/ Pleistocene Era.
The off color tip of his tail further lends to this idea, in the presumption that, as a plant-pokemon, this will "blossom" into some sort of flower, or cactus?
Any thoughts?
