Carebears, starters from past gens??
NAH-AH, GIRL/BOY. xD
Unless you have a Japanese 3DS, and you got PokeBank in the few minutes it was online, then you can't have gotten your starters from your previous games.
If you are referring to Bulbasaur, Charmander and Squirtle you got from Sycamore then they are native to Kals since you got them in Kalos.
So of course they'll have the pentagon, because you obtained them in Kalos.
