Kakamu's lab was... Kakamu's lab. It once belonged to the Nynrah Ghosts but was taken over. Kakamu used it as a laboratory, a storage space, and a testing area. Here he created the Kordaz Sabersword, the Nirak Laser-Drill, and the Nui-Kiru. He also conducted various experiments with Makuta Viruses, DNA, and even Hydrax energy here. There was clips and hooks to hold tubes and weapons. It was guarded by a number of Shadow Matoran, including Mocax. After Kakamu left the ranks of the Brotherhood of Makuta, Blackout had the contents of the lab and its entire database transferred to Destral, and left it empty. It was then destroyed by a T-4 missile fired from Destral.
