EDIT: I'm so surprisedAfter being adviced by the reaction of the downvoters.
I thoughtmore experienced users, I was doing a favornow change this to everyone by saving you the time of googling the images and offering linksa community wiki answer. Feel free to use the pokemons. It seems that I just wasted my time for nothing but downvotes.
I'll keep this postinformation here to warn myself not to do that again - at least on this site.!
Not sure if this counts as spoiler.
For those who are not familar with newer generations (like me), here are the pokemons in the picture.
Finding them already took me some time, so I hope this could help others.
