|Captain of the Guard|
|Purpose||Lead the Ta-Koro|
It appears that the Captain of the Guard was the leader of the Mata Nui Military, as he directed his forces along with the other military groups of Mata Nui. However, these groups remained independent of the Guard and did not have to obey Jaller's orders.
If something were to happen to Jaller, Kapura would become the Captain of the Guard.
