Each guardian Bakugan that is buyable by the player has something missing. Drago and Delta Dragonoid II are missing their horns, Delta Dragonoid II is also missing the blades on his tail, Tigrerra is missing her blades and the diamond on her forehead, Skyress is missing her horns, Gorem and Hammer Gorem are missing their shield and horns respectively, Preyas and Preyas II Diablo are missing their collar, Preyas II Angelo has differently shaped eyes and missing half of his hair, and Hydranoid is missing his horn. These edits were probably made so these Bakugan would not look like the owners' guardian Bakugan from the Anime.
