Many older fans might remember some of the older Bionicle sets that came with Interactive Demo CD's that were intended to help the story, but have you looked closely at them recently. If you looked at them recently you may notice the similarity to many Bionicle 2015 sets including;
- The Lord Of Skull Spiders designed as an Earth Spider that the toa would fight.
This is not the only thing that the 2001 Interactive Demo CD's seem to predict - as their is also several elemental based enemies that were possibly inspiration for the Elemental Lords based off Fire, Water, Air, Stone, Mud and Ice.
