Ah. The First mega on site was Riako's
Mega Manectric
The First Retro: on site was (pretty sure) Riako's
Retro Pikachu
And for Arceus, I'm pretty sure I own the strongest one (Which is
also a shiny)
First shiny Cubone
First shiny Marowak
First shiny Magnezone(I believe it was also the first Shiny
Magnemite and and Magneton as well. If not then Magnemite and Magneton...I don't quite remember but I do know I was
the first to hatch these three shinies.
First shiny Delphox (similar to Magnezone, I believe this
shiny Delphox is also the first shiny Fennekin and Braixen. If not
then this Fennekin and this Braixen are)
It isn't listed in the main post because we had other things to
deal with. We are doing our best to add everything to the list as
soon as possible, so don't worry, it will be added soon too. As you
can see your Pokémon isn't the only one that hasn't been added to
the list yet. Thank you for understanding and have a nice day.
^^
Edit: We have updated both posts, thank you for the help. :)
@MonsterTruck, please read the first 2 posts carefully again. "To
be considered for the Strongest Pokémon, it needs to be level 750+
or that you are 99% sure it's the strongest in game." Thank you. ^^
