So, is there any way to get a Dream World starter, like Speed Boost Blaziken whiteout hacks? Is there any starter that has been realesed with their DW ability? Has there been any event to get them?
Yes there was an event for the DW starters of Hoenn. There is an event for the Sinnoh starters right now. You have to purchase a special Pokemon B/W2 game and enter the code in the DW. The rest of the DW starters are unreleased. Only native to Japan.
