The Battle of Onu-Koro was a battle between the Onu-Matoran and Gahlok.

Gahlok first flooded Onu-Koro, prompting the Matoran to be evacuated. However, Onepu, Taipu and Nuparu got trapped. Inside, they discovered a disabled Gahlok and used it to build a Boxor. They then fought the Gahlok and won, gaining back Onu-Koro.
