These little guys were Bohrok-va that were modified by a Makuta from the southern parts of the Matoran univers. They are used by their creator as enforcers.
The calm leader of the group,who always plans things, even while resting. He is as intelligent as he is merciless.
The zealous warrior, who sees the Makuta as gods. She enforces Makutas rule with merciless brutally.
Honestly I made them for fun.
