The Bionicle Stars are the line of small sets of 2010. BIONICLE author Greg Farshtey has confirmed that the Stars will be a part of the storyline, although their size is like Titan Mata Nui's: simply a different representation. In every set of this line, an extra golden piece was put. This was meant so if you collected them all you could add the golden armour to Tahu. The sets are:
Tahu
Nektann
The yellow Rahkshi
Gresh
Takanuva
Skrall
Back of the Rahkshi Box
