It's in the rules.
"You can choose any Pokemon from any region, but it cannot be a Legendary, and it must be in the first tier of its evolutionary line. You can start anywhere between levels 1 and 10, unless your Pokemon would evolve right from the get-go based on your level choice."
So yeah, first forms only. (Or singles)
