You know what it reminds me of? Diancie.
Like, look at this:
It could be a little far-fetched sure. But the resemblance is there.
Well there could be two reasons for this:
Ken sugormi expressed how in future, they wanted to simplify pokemon designs. So maybe that meant basing them on other designs and simply the look?
or...
This pokemon was made by an ancient tribe who saw diancie and what to create something like it. Which leads me into my new type theory...
its...
GAME THEORY TIME!
Pokemon Z will be announced within the next few days( or by the end of the month), alongside this pokemon.
Pokemon Z will be the literal other half version of XY.
There will be two regions. This is slightly alluded to with XY's ties to other regions.
70 more pokemon will be added( to double XY's amount.)
The game will be two versions with a core as the focus of each one. The plots will overlap though.
There will be a new type to coincide with fairy.
This type ( my name prediction, not entirely accurate) will be magic.
It will focus on pokemon that are man made/ ancient( think claydol), and have magical qualities to them.
This pokemon will be metal and magic. My prediction is that it is a man made pokemon, but by an ancient tribe. Using some type of dark magic, they bring to life a pokeball like object and it becomes magianna.
Also it's definitely Gen 6.5, hence why it's such big news that a new pokemon is in the movie. If it was for a new gen they wouldn't bat an eye.
Ahem.
Dragonite: 463.0 lbs.
Capable of flying at speeds which go up to going around the globe in 16 hours.
Jessie stops it mid flight with just a frying pan.
Edit: To put that speed in perspective, its about 1,553.5 mph. About TWICE THE SPEED OF SOUND.
Don't your remember, they are the ultimate weapon!
