Gakarl is a Matoran from the Tren Krom Peninsula. He went to the realm of Karzahni to be repaired some 100,000 years ago. He was kept there for over 50,000 years. The being Karzahni was very bad at repairing Gakarl, and so gave him some weapons to compensate. But one of the Matoran rebels betrayed the rest. Karzahni immediately set the Manas on them. The Builder of the Canisters escaped the massacre. Gakarl thought about helping his friends, but another side of him emerged. He ran to the sky-speeder and flew off. The vehicle took him out of Karzahni, and into lands unknown.
