The way they are advertising it, it would seems its a new Pokemon altogether and not a form. "a Pokémon that is strangely familiar to Legendary Pokémon Mewtwo!" This tells me that the Pokemon will be new because they would have said it would be a new form. "This new Pokémon shares many traits with Mewtwo and it’s suspected that the newly discovered Pokémon has a connection with Mewtwo". Note the keywords new and newly discovered. This tells me this Pokemon has its own number in the Pokedex, which makes it a completely new Pokemon.
If the way they advertised the new Pokemon by only saying that it was similar and that's it, I wouldn't be making this argument. Check on the Pokemon X & Y section of the Pokemon site, then go down to the slide underneath the images of the new Pokemon. Here is what each page on the slide says:
1: The Legendary Pokemon Mewtwo
It is suspected that the newly discovered Pokemon has some sort of connection with the Legendary
Mewtwo-a powerful Pokemon that first appeared in Pokemon Red and Blue Versions.
2: Discovering Mewtwo
To find this powerful and mysterious Pokemon in Pokemon Red and Blue Versions, you must first enter the Hall of Fame, then travel deep into Cerulean Cave. At the time of it's discovery, Mewtwo reigned as he most powerful Pokemon that could be found!
3: A Pokemon Engineered for Battle
Mewtwo was created by engineering the genes of another powerful Pokemon, the Mythical Mew. The aim was to create a Pokemon that would be mightier in battle than any other Pokemon!
4: The Legend of Mewtwo Endures
As recently as Pokemon HeartGold and SoulSilver Versions, you could capture Mewtwo in Cerulean Cave, just as you could in Pokemon Red and Blue Versions. The power of Mewtwo stands the test of time-it is still considered one of the strongest Pokemon ever discovered!
5: A New Chapter
Now, a newly discovered Pokemon appears in Pokemon X and Y-a Pokemon that bears a curious resemblance to the Legendary Pokemon Mewtwo.
I'm arguing that Pokemon is giving us hints that this new Pokemon is Mewtwo's new forme. Here are the clues I've found:
1: It looks like Mewtwo
2: If this was a whole new Pokemon then why would they show the history of Mewtwo?
3: Why would they show the new Pokemon battling Genesect? For fun?
4: On the movie poster why would Mewtwo be missing and the new Pokemon standing behind Ash and the crew? If the new Pokemon is an evil clone like everybody seems to think is, the Pokemon has nothing to do with Ash and his friends.
5: Before they revealed the names of Xerneas, Yveltal and Sylveon, they had the same number of question marks as the letters in they names and now the new Pokemon has 6 question marks instead of 7 meaning it's name has 6 letters in it so names like Mewthree won't fit but the name Mewtwo fits perfectly.
This all looks logical to me that this is proof that the new Pokemon is Mewtwo's new forme. I know people are going to whinge and whine about me being wrong and this information being illogical but before they call me wrong, I would like to see some proof they've found that would promote the idea of a clone instead of a new Mewtwo forme. So if someone wants to prove me wrong, they have to find some proof first. On the 18th, there will be a new Genesect movie trailer, that'll prove if the Pokemon is a clone or a new Mewtwo forme. Before end this comment, I want to ask, why do people want a whole new Pokemon instead of a new forme? I personally love forms if they can be added to Pokemon because then there's so much more variety for that Pokemon, while if the new Pokemon is a whole new Pokemon, then Mewtwo will slowly be forgotten.
And vaporeon, what would be the point in them saying the new Pokemon is similar if it's not a new forme? That's just messed up. Also, remember they said the same things for other Pokemon forms before they revealed them like the new forms of Tornadus, Thundurus and Landorus.
