Something that confused me about G2 of BIONICLE was their villain lineup. There always seemed to be for the main lineup (at least in G1) 6 heroes, and 6 villains, there were smaller supporting characters that could be heroes or villains (Bohrok Va, or Rahaga for example), and there might be more heroes and villains in the form of large titan/warrior sets as well, but for the most part, there were 6 heroes and 6 villains. (the exception to this was 2009 when with the glatorain, the heroes and villains were really mixed up, with the Skrall being the main baddies, and then minor villains in the story as well, e.g. Malum, Strakk, Vorox etc.)
Come G2, you get the 6 toa and their smaller helpers, but you only get the LoSS, and little spiders mixed in with the Toa/protectors. Later in the year the skull villains are introduced and you have 4 sold individually. the fifth one is Skull Basher and he is sold with Ekimu so he's more of a titan set than stand alone.
Fast forward to the 2nd year of G2 and you have the 6 toa and their critters, you have Umarak as the villain, but you only get 3 elemental creatures for the second wave.
So what happened? Was it a marketing ploy? Were they winding stuff down that last year and decided "we only need 3 villains to fight the Toa."? What do you all think/know?
