I know many people don’t like the idea of Ash-Greninja but I personally love him and want him on my team. Sadly I can only get the one greninja in sun and moon because nintendo is a butt and wont allow me to breed or find my own. So I was just wondering if he was going go be in the game or not?
Oh god no.
Nope, nothing from gen 7 will be added
But Ash-Greninja is from gen 6 ;-;.
They mean gen 6 games. Though it was in the XYZ show, at the time we had no clue how its ability worked, it’s stats, etc. So there was no way for them to implement it as there was no information
I understand cow cult leader.
As I said in a previous post, as an alternative you can use these sprites: Ash Greninja Sprites
You just have to change some sprite files in the graphics folders.
