this is pretty complicated so I'll keep it short and sweet.
When you migrate a Pokemon, whatever level it was when it evolved, (Metagross LV. 45)
It will become that level, this is because, if you just migrated lots of high level Pokemon, you would easily beat the game and it would be a waste of money because you would have done it in 1 or 2 days.
...shiny Pokemon are always shiny... ._.
No matter what Pokemon it is and if it is shiny it will stay shiny if you trade it or migrate it, trust me i know i traded my shiny banette to Pokemon xd and its still shiny.
Luck.
You cant get a shiny eevee on Pokemon platinum unless you have some sort of cheets. NOT TRUE... get a shiny eevee if its the swarm of the day and then just chain them..
Yes. Apparently it is easier to hatch shiny Pokemon from an egg in Platinum if it's parents are from another country.
the chance of getting a shiny Pokemon is 1/8496.
On Action Replay press disable Shiny Pokemon.
Shiny encounter action replay code for platinum: 12075E52 000046C0.
get Pokemon platinum and fill the pokedex and then get the Pokemon radar, a tool which lets you get shiny Pokemon faster
in action replay ds select wild pokemons are shiny.
The only way to get a shiny Pokemon is by a random encounter or by trading with another player.
Only the togepi egg has 50% of being shiny
