Abigail "Abby" (Gilligan) Lincoln a.k.a. Numbuh 5 is the intelligent, relaxed girl second-in-command/spy in Sector V.

She became a KND operative three years. She was trained by her older sister, Cree (Numbuh 11), and joined her sister, Numbuhs 8a and 8b, and Numbuh 9 in Sector.

Numbuh 5 has been very close with you since the beginning of your initiation of becoming a KND member, because when you arrive at the treehouse she hugs you.
