These creations are by Lady Bluestreak (BLM)

I remember using Slizer torsos and T-shaped liftarms to make psuedo-Mata bodies in dark gray, yellow, and purple. Here you can see ProtoToa, Rahmuran, and an earlier version of Voriki.

Lady Bluestreak (BLM)

I love how Lady Bluestreak built toa mata style bodies in colors The LEGO Group never manufactured, using throwbot parts from their earlier experiments with action figures. Some colors like purple were just hard to manufacture, while other were likely avoided in later generations due to the popularity of the original 6 toa.

If you want to check out more of Lady Bluestreak’s creations, you can find her twitter account here! She does have other interests like classic gaming, mecha, transformers and etc. to check out while your scrolling through to find her BIONICLE content. More recently her LEGO content has been brick based, although you can find plenty of revamps, set/combiner modifications as well as CCBS focused MOCs if you dig deeper.
