Frequently asked questions

What was the Ga-Koro Defense Force?
The Ga-Koro Defense Force was a small Ga-Matoran unit of the Mata Nui Military tasked with patrolling Ga-Wahi and protecting the lily-pad village from infected Rahi, Bohrok incursions, and other regional threats. Its members operated from green motorized boats armed with bamboo poles, and the village was ringed with bamboo to deter approaching wildlife.
Who led the Ga-Koro Defense Force?
The unit was led by two Ga-Matoran of equal rank, each designated Co-Chief. Hahli and Macku held this office, and the dual-command arrangement let one Co-Chief deploy on the water while the other remained at the village.
Who were the members of the Ga-Koro Defense Force?
Six members are recorded by name: Hahli, Macku, Amaya, Shasa, Kotu, and an unnamed guard who wore a Kanohi Pakari and was charged with tending a captive Tarakava during Kotu's absences. Most other Ga-Matoran likely served part time given the village's size, but only those six are documented.
How did the Ga-Koro Defense Force defend the village during the Battle of Ga-Koro?
When the Pahrak advanced during the Bohrok War, the Force used Kolhii sticks to demolish the Ga-Koro Bridge, severing the most direct route into the village. Because the stone-element Pahrak were not buoyant, the Ga-Matoran worked with Po-Matoran Hewkii to force the remaining bridges upward, plunging Pahrak into the water and rescuing Macku, and the village survived.
What auxiliary forces did the Ga-Koro Defense Force use?
The Defense Force fielded several Keras crabs during the war, originally tamed by the Onu-Koro Ussalry. After the conflict the Keras were released into the wild and rewarded with Ruki Fish to preserve a working relationship in case of future need, with the understanding they would be recalled if a Rahkshi assault or second large-scale invasion struck Ga-Koro.
