Rieko's true form.

Rieko is a mysterious woman from Professor Gill's past. Akira's guardian. Usually appears in disguise. Although she has no alternate name, Rieko is an android. In the live action and manga, Rieko knew she was an android, but in the anime she believed she was human due to Professor Gill installing her memories of another child with the same name. Her android form is similar to Bijinder's form but with two shades of gold with her 'hair' modeled into a sort of swept up bun. She has a green jewel in the center of her forehead with which to shoot a laser at her enemies. Rieko did not change her appearance in the live action.
