Shadow Leech

"What slipped past Tanma was a slime-covered leech about two feet long, faintly glowing with a pale, sickly light."

- Shadows in the Sky

Shadow Leeches were mutated kraata that had the abillity to suck light out of Matoran and Toa. The Matoran would then become a Shadow Matoran gaining the element of Shadow and losing their abillity (for example if a Shadow Leech sucked all the light out of a Ko-Matoran, he would have lost the resistance to cold upon becoming a Shadow Matoran).
