Here are 5 main reasons why this Pokedex is fake:
1.
Mokurou, Ashimari and Nyabii are confirmed trademarks and have been suggested to be the Grass, Water, and Fire starters.
Mokurou is likely Moku (Tree) + Fukurou (Owl)
Nyabii is likely Nya (Meow) + Hi/Bi (Fire)
Ashimari is likely Ashika (Sea Lion) + Marine
Every upcoming generation of Pokemon, fans always have a badly poorly drawings of starter Pokemon unconfirmed by gamefreak. Guess what? Most people are always fooled by them. Remember fake starters from the previous regions?

2.
Too much ice. Alola is a very tropical region, there is only one area that contains frost. If we have approxmently 100 new Pokemon, don't expect more then 5 ice types. Back in D/P, there was only one area containing magma. Sinnioh only had 5 new fire types.
3.
The guardian Pokemon are not in order. Pokedex goes in order of where you find said Pokemon so the "Psychic Tapu" should be before the "Fire Tapu" as we already know you got to Akala island second. Besides, I doubt they all have "Tapu," in their name. Seems quite lazy if you ask me.
4.
Marshadow is trademarked. If the name were meant to be Malshadow, it would be written マルシャドー (Marushadō). マーシャドー is clearly meant to be Marshadow and is even trademarked as such.
5.
Gigareki is trademarked. My favorite one to talk about. Gigare means Giant in Latin. The "ki" at the end comes from "tiki." Since Zygarde arleady the order Pokemon based on the protector of earth. Gigareki is said to be large or small wooden or stone carving humanoid containing the power of earth.
The other legendary Alola Pokemon names are based in Latin as well.
Solgaleo’ suggested a lion-based appearance (with ‘leo’ being Latin for lion). Naturally ‘sol’ is Latin for sun, giving the Pokémon a clear relation to the solar object.
About Lunala, "Luna’ was the obvious word to pull out, as it is the Latin word for moon. "ala" Latin for winglike anatomical process or part, especially of bone.
Why is everyone keep getting fooled by this nonsense? Remember the first fake Alola Pokedex leak back in February? "Gen 6.5":
To 100% confirmed the fully evolved starters and Pokedex to be a counterfeit, I"ll see you all this Friday.
