You will become a pokemon trainer in the pokemon world, (Yay!)
BUT
All the legendaries will begin fighting and it is YOU (along with 5
or so people) who has to deal with them all! (I think that
it is a Yay!)
You can go to the Pokémon Anime and start your journey as a
Trainer. BUT
When you throw your Pokéball to call ANY Pokémon, a Magikarp
(holding everstone, non-shiny) will always come out and use Splash
at YOU and EVERY egg will hatch into a karp....
All Pokémon will come alive (including ones which you have
caught even those caught in the games and Browser games like PH or
UnovaRPG) BUT
Feebas and Magikarp will lose their Evolutions, Mega Evolutions ,
Shiny Versions and mega stones. And the Gyrados and Milotic which
you have caught(and are supposed to be alive) will revert to The
Non-shiny, non-mega Feebas and Magikarp.
Any Boy/Girl you desire will fall in love with you
But
Every time a Girl/Boy you desire is near you, their face will
become an exact replica of your own
" All it costs is your love!! " Welcome! I am quite friendly and I love chatting as well as
meeting new friends. [she/he/they]
You will get 1 of each Kalos Legendary and Mythical (Xerneas,
Yveltal, Zygarde, Diancie, Hoopa, and Volcanion. Not including the
new Magina) 's shiny form, but you can no longer encounter rare or
legendary Pokémon or get them from B2W2, PokéBank or the GTS
(includes Wonder Trade) anymore.
(And yes, this is in X/Y/OR/AS and all the future games)
