What is so great with this pokémon, that it got an animated film, with its name in its title!?
And to say that a Gardevoir's scene was scrapped in Detective Pikachu... *Sighs*
Porygon is not that bad! You just have to waste lots of money to get enough casino coins so you can acquire it, then you do a trade for it to evolve (with a special item!), you get it back (with another special item!) to evolve it again, you trade it again so your fellow trainer can get its entry too, then trade it back again to get it back! Easy!
Deoxys ?
