Mana-Ko

Mana Ko were legendary crab Rahi believed to be Teridax's ultimate guardians. Mana Ko tracked their prey by movement and could fire energy blasts. For all their power, they weren't very bright, when the Piraka encountered two in Teridax's lair, their repeated attacks kept blasting open escape routes for the thieves.

The Mana Ko were in fact secretly loyal to the Order of Mata Nui. The Order tolerated the Brotherhood of Makuta's use of them, as the Mana Ko sent vital info back to them, as well as guard Brotherhood weapons that the Order didn't want falling into the wrong hands.

Set Information
The Mana-Ko can be created by combining the two Manas in the Manas 2001 Titan set.
