Within the Time Bokan franchise, Noriko Ohara is most well known for her roles playing the various female bosses of the trios through the shows: Marjo (Time Bokan), Doronjo (Yatterman), Muujo (Zenderman), Atasha (Otasukeman), Mirenjo (Yattodetaman), Mun-Mun (Ippatsuman), Yanyan (Itadakiman), and Rouge (Kiramekiman). She would return to voice the character/s in any role after, including the 2008 Yatterman series, and providing the final line in the last episode of Yoru no Yatterman, where her voice as Doronjo can be heard wishing her descendant Leopard, "Good night, sweet dreams".
Her iconic line of "Sukapontan!", used when yelling at her bumbling two lackeys was an ab-lib that combined Sukatan (stupid) and Anpontan (fool) because she felt the original choice of insult in the script was a little too harsh for a kid's show like Time Bokan.
