They appeared as only crystals that store all the data of a specific Legendz. Most of them that are on sales, distributed to children as toys aren't real souldolls. Ken's Shiron, Leo's Greedo, Kaoruko's Bjork the Golem are all real Legendz reborn from the souldolls.
Again, all the souldolls on sales along with the toy talispods, are fake souldolls that only created the images of the Legendz. For the other souldolls they are all real.
