You want leaks? Fucking fine. I'll tell some info about the new forms of the legendaries.

I've not seen much about the name of the legendary forms thrown around, but I want to mention they are called Prism form. The only thing that really changes is a few moves and their ability, which is they get Prism Armor. They do get Prismatic Laser as well. Their stats change very lightly, at least it seems (Very complicated to tell what exactly is happening, since the playtesting is weird.)

No, the Prism form isn't some Kyurem Fusion bullcrap. This is essentially a Gracidea Flower type deal, or the Mirror for the 'nadus line. No, Ultra Beasts do not get this, at least from what I know.

This is all I know since I'm play testing this stuff. This will be my only post about this.
