For stars? Where do I even start? I'd have it be a bunch of sets. Each set of the 6 would be large, containing multiple figures. Like said in a podcast, I would have pieces for a Mata nui, and a Makuta robot
Set 1: the last stand
Tahu, Takuanuva, and Gahli have collected the 6 pieces of golden armor, but are surrounded by an army of rahkshi. Tahu must destroy them all. 3 other figures would depict the same 3 types of enemies in the final year, but in actual sized like before
Set 2: A team up
Pohatu, Kopaka, and Onua meet Gresh, Kina, and Ackar. The 6 decide to fight together.
Set 3: Fly alone
Lewa fights alone, against unexpected enemies, the piraka, except for Vezok.
Set 4: The Rahaga reformed into Toa. Brought back from old, these warriors fight to make up for the time they've lost hy fighting for justice, they face 3 rahkshi.
Set 5: Behind the scenes
The turaga escaped from the Makuta robot, meeting the leaders of the agori, together they face one gigantic Skrall.
Set 6: (Build able if all 5 others are collected) The final battle. The Mata nui robot vs. Makuta. Bonus moons added into the set as well, along with both a crisp black mask of Shadows, and a solid gold mask of life (2007 version)
