Yeah it's another baseless rumor from 4chan but it does seem realistic and makes sense, plus yeah I obviously really want this to be true with how amazing this list is! We'll know if it's fake or not in just 5 days so I definitely think it's worth looking at.

I read this. I hope its fake, I want another octopus Pokemon ;~; or maybe an Alolan form of Octillery >:3

Fire/Water is real already 

I'd say 100 is plenty, and that's not even including Alola forms.

Ice-type Vulpix and no Gyms also sound fake. Plus Volcanion exist already. Grass/Fire is inevitable and really needed since it's one of the best Grass dual-types.

Atleast you already have your Octopus Pokemon, I've been waiting 10 years for a Dolphin Pokemon, just let me have this man!

That's true v.v I hope we get the dolphin!

Various? As in, more than two types? Wut?

104 new pokemon is perfectly plausible considering there will be Alola forms to old pokemon, which basically will work as new pokemon as well.
There was a rumor that the final evo for the starters could have more than 1 type combo, which seems to be the case if this Pokedex is real. And that works great for Rowlett,

So there IS a dolphin pokemon. :) 

There are multiple options for the secondary type. We can see this with Rockruffs final evolution Weruff who can be Rock/Steel, Rock/Flying, Rock/Dark, or Rock/Fighting. That would explain the connection Gamefreak said it has with the Starters.

Well that's IF this leak is true, which is the main reason why I want it to be! Not only would we be getting a Dolphin Pokemon but it'll also have options for it's secondary type. That's just awesome and would exceed my expectations considering I thought for sure it'd be Water/Psychic, but if this is true it can be that or more, making it easier to fit on any of my teams! 

Shoulda actually read through the thread first, as the leaker list the specific secondary typings for the Pokemon with multiple options.

"OP here to clear up some questions...

Robinroot: Grass/Flying, Grass, Grass/Ground, Grass/Electric

Beltigre: Fire/Dark, Fire, Fire/Ghost, Fire/Poison

Sirene: Water/Fairy, Water, Water/Fighting, Water/Psychic

Weruff: Rock/Dark, Rock/Fighting, Rock/Steel, Rock/Fairy

Porprise: Water/Ice, Water/Steel, Water/Fairy, Water/Dragon

Darline/Darwisker: the fabled breed cats. Normal/Anything.

Snohom/Snorror, Rugrilla, Delfin/Porprise, Fungkie/Hallucid, Cumbersum/Anenemie all got mentions in previous leaks as well.

Malshadow has some kind of type-shifting ability, but i don't know any more on that at this time."

Really, really, REALLY hope this is true! Those are amazing and also rare type combos for the Dolphin!

I would definitely be satisfied with 104 new Pokemon after XY gave us only 72. I still kind of doubt this to be true at this point since 4chan generally isn't too reliable with rumors.
