Upon receiving the signal that the Bohrok have fulfilled their destiny, their body begins a metamorphosis. Upon receiving the energy pulse of the Ignika’s life energies on Spherus Magna, their krana fuses into them. This returns organic tissue into their bodies. These former Bohrok are given new life for completing their duty to the Great Spirit and are allowed to live a new life on the new world.
Also some alternate designs I made. I feel like the first looks more like an evolution of the Bohrok body but these designs just look nicer in my opinion.
