Genki Sanban

Genki Sanban is Kuki (Numbuh 3) and Mushi Sanban's mother, married to Kani Sanban. She has a stern demeanor but cares for her daughters. Genki is sharp and observant, helps solve mysteries, and is head of accounting. Voiced by Lauren Tom, she is the only Sanban family member with four kanji characters in her name. Genki becomes Numbuh 4's mother-in-law in the series finale. She works at Werk Co. with Sydney and Betty, and her absence is noted in "Operation: H.O.T.S.T.U.F.F." due to a business trip.
