Numbuh 5

"Numbuh 5 says that Roll is right. She may be my friend but Numbuh 5 says that we can fight for peace and freedom."

--Numbuh 5

Abigail "(Abby)" Lincoln a.k.a. Numbuh 5 is the intelligent, relaxed African American/French girl second-in-command/spy in Sector V. She became a KND operative three years before the show started as shown in Operation: M.A.U.R.I.C.E.. She was trained by her older sister, Cree (Numbuh 11), and joined her sister, Numbuhs 8a and 8b, and Numbuh 9 in Sector V. She sings just like Numbuh 3 but her lullaby puts the babies to sleep.
