The game character however was done by different party or parties who take took the concept and adapted to the game usually with little actual communication with the original designers or concept artists. Every game after diverges a little more form the concept, best example Pikachu look at his concept Gen 1 to Gen 7 its changed quite a bit from what was originally conceived.
That is why if we are looking at the intent of the design, you go back to the original art and concepts not the game. QED
