(Update: 11/12 I filled in some spots on him and added a couple of parts and changed out blue axel pins for black ones.) Leweru Toa Of Air: A hero of the Toa Dark hunter war. Thought to be dead by his brothers and sisters and the reason for Onebua donning similar armor in homage to the fallen hero, was found by Matoran miners in a tunnel to the south alive! His left arm and legs were amputated by dark hunters when in battle with the enemy. Though he put up a good fight, he was hopelessly outnumbered and lost his limbs in the conflict.
Thought dead by his foes, he soon crawled his way with one arm to the closest cover in a cave, there he stayed surviving any way he could until the day he was found. The Matoran he was brought to knew he was a veteran Toa of the war and thought no ordinary limb replacements would suffice. So they fitted him with the most advanced legs and arm available. He is now ready to get back out there and be the hero once more!
