>>8740382The bionicle designs themselves are based on lego pieces that are probably litigiously guarded.. What would you want from 3P Bionicle? The basic designs but with more articulation? Or more elaborate designs not limited by being a children's building toy? If you redesign it, you run the risk of alienating people who have their own vision of what the designs "should" be. Various fanarts and MOCs seem to show that a lot of fans have their own mind's eye interpretation of the sets.
