Is there any way to get Darkrai in Platinum with out network?

Question

I have 2 Nintendo 3DS systems, if that even could be a way to get it.

Answer 1

Nope. The only way to get darkrai is the event which has passed long ago
or you can get it in a trade. Darkrai cannot be found in Pokemon platinum.
Darkrai can be found in the Pokemon dream radar though.
Hope this helps.
