Numbuh Five (real name Abigail Lincoln) is one of the five main characters from Codename: Kids Next Door. She is the spy and espionage tactics expert of Sector V, as well as the second in command (since she's easily the most level-headed of the group), and keeps guard over their candy stash. She talks in third person about herself, due to her calm, cool personality. Her sister, Cree (formerly Numbuh 11), is her arch-nemesis. Numbuh Five is also the one who convinced Numbuh One to join the KND. As an adult, she married Numbuh 2.
FusionFallEditIn FusionFall, she is the first to greet the player in the future, alongside Ben and fills them in on the details concerning Planet Fusion and Fuse's plan of absorbing the planet. She is located at the Pokey Oaks North Mall in the future. In the past, she can be found at Genius Grove, with Professor Utonium and Dee Dee. Her Fusion is first fought aboard the Sweet Revenge, the gooey remains of Captain Stickybeard's ship at Candy Cove's infected zone. Her hidden lair is within the maze at Foster's Home, with Frankie mentioning that she wanted an imaginary friend of her own. She gets her wish, even though this is the player disguised and ultimately defeats her. She is also at Mt. Neverest when the player graduates.
- Numbuh Five is the one of the only two from Codename: Kids Next Door to appear in both the past and future, the other is Numbuh Two (and Numbuh One if you count his cameo appearence fighting alongside Dexter.).
- Numbuh Five is one of only two people who refer to themselves in the third person (saying their own name instead of "I" or "Me"). The other is Dracula.
- She and Numbuh Three are the only one from the KND whose nano type isn't the same color as their sweater.
- Her archenemy is Sticky Beard, so her fusion being found on his ship, Sweet Revenge, is probably a reference to this.
- On the show, it is mentioned that kids are decommisioned from the KND at age 13. However, in FusionFall, all of the KND members are at least that old. It is assumed by most that the age of decommisioning was changed to about 18. The more likely explanation is that they haven't actually reached 13, and are closer to twelve.
