Negative Numbuh 1 is the counterpart of Nigel Uno a.k.a. Numbuh 1 of the Kids Next Door. As Nigel's opposite, Legin is shy, weak-willed, and easily manipulated, unlike the bold, strong-willed leader that Nigel is. Most of the time, Legin lets himself be bossed around by his ex-girlfriend Eizzil Enived; it was she who convinced him to help her capture Nigel after she already captured Lizzie. However, Positive Nigel saw through their deception after looking Eizzil in the eye and guessed they were in a reflective world. Legin claimed that their world was perfect. However, Nigel correctly suspected that his counterpart was not in charge.

After Ynnaf freed the KND from the Broccoli Mines, Legin got to watch as his ex-girlfriend kicked Eeballaw, his former leader through the portal back to the negative world. With Eeballaw no longer leader of Negative Sector V, Legin has likely taken on that position after overcoming his fear. His name may be Legin Onu, though this is unknown. He and Nigel in Operation: C.A.R.A.M.E.L. are slightly similar.


  • His name might be Legin Onu, though this is unknown.
  • Negative Numbuh 1 shares similarities with XL off of Disney's Buzz Lightyear of Star Command, being that they are both evil dopplegangers of Nigel and XR.
  • His tooth is knocked out when Nigel and Lizzie escape the DNK treehouse.
  • Although unconfirmed, after the events of Operation: G.I.R.L.F.R.I.E.N.D., he may have gotten back with Eizzil after Lizzie left Positive Nigel.
