Ultraman Wiki

Shinryoku (深緑シンリョクlit. "Depth Green") is the final Nature Control Machine in the series Ultraman Gaia in episode 46. Shinryoku's purpose was to replant the Earth's forests, the final step to repopulate the Earth.

As Catherine Ryan of Alchemy Stars found out, Shinryoku was built using human technology, with its inner workings being a carbon copy of the energy plant Ent that she proposed on Canada. This was later confirmed by Yabuki Shirogai, who stated that Shinryoku was created by mankind from the future after they submitted to the Radical Destruction Bringer.
