Quoted By:
-Non coomer design (no skin shown, no huge boobs)
-not a big role in the game in DP, only somewhat expanded in Platinum
-role in the DP anime bigger than Lance/Steven had in OS/AG, but still not very big
being female isnt an answer - see Diantha and also other less popular pokegirls (often with more coomer designs)
she wasnt being pushed/shilled during gen 4, that happened after when they saw she was already popular
So what was it ?
The battle ?
The Garchomp ?
The piano theme ?
