I don't want to seem rude here, so just know that I mean this message with the highest of respect.
It's true that those two pages may have been faked, I'll give you that. But if you go to Serebii and look at the page with Aloe, you'll see that Pokabu's evo is right next to her. Now if you counter saying that that page is fake, then go to Pokebeach and look at the two pages with both Aloe and the Dento leaders and the Monkey Trio. If you look at the crease, you'll notice that; 1. The bottom left part of Mokoma's skirt is continued on the next page, and matches perfectly. 2. Poddo(I think that's his name)'s cuff and his right leg both continue onto the next page, and also match up perfectly. Now personally, this is enough evidence to prove that the page with Pokabu's evo is true, and thus, Chaobuu exists, and leads me to assume that so do Janobii and Futachimaru.
Once again, I make this statement what the utmost respect towards everyone. I'm just throwing my beliefs in the mosh pit.
