Tbh I don't think it's legit. I'm not saying it's not possible, it still kind of is and I'm still open to it. But sense that Pokedex list and numerous other leaks/rumors that also mentioned the split evos can be proven fake just from these Corocoro leaks alone. Or at least take the credibility away. I'm just more skeptical than I was before.

If anything, I think this pic is closest thing we have to what starters evo's are going to possibly look like. Either exact or little bit different.

I guess we just have to see what Corocoro has to say about Rockruff evolution next month. Which could be tied to the starters evolution.
