you can get seals with the unknows
The Solaceon Ruins.
no, these Pokemon are unknown in Pokemon platinum
They are the alphabet :)
That is unknown.
In Diamond it is in the ruins with the Unknown, I am not sure about Platinum though.
You can either get it by capturing it in Pokemon Silver in the Safari Zone. Or by trading it on the Global Trade Station in Pokemon Diamond, Pearl, or Platinum.
It's currently unknown which countries Pokemon Platinum is gonna be launched anywhere else, other than Japan.
lightening bolt
At the Solaceon Ruins in Solaceon Town, different rooms has specific Unknown in them. . . so its kind of HARD to get a specific Unknown. . .
After capturing Giratina, go talk to prof. Rowan in Sand Gem Town.
You can find the M form of Unown in the Solaceon Ruins of Pokemon Platinum. This form of Unown appears in the dead-end rooms of the Ruins.
Yes you can at the Solaceon Ruins. Battle/Catch 99 Unknown and the 100th Pokemon you see will be Celebi.
