Roboko

Roboko is an AI robot constructed by the assassin Marin to stand in for the kidnapped Satoko. Despite her distinctly metallic appearance, she won Konoha's affection through her exceptional housekeeping skills and her ability to dispose of evidence without a trace. Equipped with powerful weaponry including eye-beam attacks, her remarkable work efficiency even posed a threat to the real Satoko's standing. She serves as both a source of comedy and a genuinely formidable presence throughout the series.
