Seeing the genius of the Rigelians and wishing to use it for their own, General Giluke chose to place a plan in motion to manipulate one of these genius children to assist their forces. His forces end up taking a young girl named Nana without telling her she has left the world, creating the illusion that she was still on her homeworld while killing her father and replacing him with Dr. Kumazawa, an Earthling lookalike who wished to betray Earth to gain intergalactic power. Without telling her the truth, Nana assisted them in a project to empower Gyodai with energy to grow creatures on a massive scale without tiring as typical whenever the Gyodaian used his growth beam. However, the intervention of Hiryuu Tsurugi made Nana realize she was no longer on her homeworld, yet with her staying on Earth instead even after the betrayal to find further information about this backward world.Ep. 13: Papa Sells the EarthEp. 14: Attack!

The beings of Rigel possess great power which they exhibit generally at one point in their life. The girls of the planet release a special "Rigel Aura" from their bodies at the end of their short childhood, with the energy flying out of their bodies as they transform into adult forms. Nana likewise mutates into a young adult, with her Rigel Aura bathing Queen Ahames giving her powers herself. Similar energy also is emitted from the lifeforms including dragons who live on the planet, such as Kukku as it sacrificed its life to save the Changeman.Ep. 32: Nana!
