I'm not a denialfag but can't help but feel that the leaks were scraped, it's clearly official and I thought that they were real ever since the mallow incident. But these second stages seem a little too different from the leaks.

While brionne does look like it would totally turn Into popplio3 as it has a very similar theme however torracat losing its theme to become a wrestler and dartrix completely losing its dapper knife thrower theme to become a sniper with a bow and arrow just seems a bit to much

I know starter can change they're appearance drastically when they evolve(chesnaught, sammorot) but only one has ever lose its theme. I could still see the leaks being real but I just have my doubts
