Mistika was the name of the Toa Nuva and Makuta in the Swamp of Secrets. It means "Spirits of the Mist" in the Matoran language. The six Mistika were Tahu, Gali, Onua, Krika, Bitil and Gorast. Both sides carried tools known as the Nynrah Ghostblasters, and they all had a place on their backs to put the Matoran like the Phantoka did. Takanuva was also known as one of the Mistika warriors.
- The lids of the canisters were designed to look like the Kanohi Ignika.
- All of the Mistika sets other than Takanuva included Nynrah Ghostblasters.
- This was the first canister series to include two female sets (Gorast and Gali).
- The lid of the canisters had different designs on each side, scarred and non-scarred. The Makuta canisters had the Ignika lid facing left, showing the scarred side. The Toa canisters had the Ignika lid facing to the right, showing the smooth side.
Despite being female, a typo in the Bionicle Mistika Game says "Gorast uses his stinger" instead of her.
