>>48687732This was a thing ever since the original gen 4 games, in fact it's even a plot point. Trying to capture one of them with a Pokeball just gives you a weakened "avatar" of them they leave behind for you, one with limited power. Cyrus was aware of this, so he sought out another method to harness their power, that being the Red Chain.
This game looks like absolute garbage, but I will admit, having a secret boss fight with an uncatchable level 100 Giratina that evokes the image of their distorted version from platinum IS a really cool idea. It helps to sell the fact that at the end of the day, the creation trio's "fights" are just them testing you.
