- "I'm Lasso Lass, the rootin' tootin'-est shoot-em-up hootin'-est ain't that fat cowgirl this side of the Mississippi."
– Lasso Lass introducing herself to Sector V
Lasso Lass was the leader of The Cowboy Kids Club, a group of kids that fought against adult tyranny. She continued the fight well into her adult years and helped Sector V attack Mr. Wink and Mr. Fibb, after which she disbanded her group.
Personality[]
Lasso Lass was a kid at heart, even though her hair turned gray and she was growing old. When she met Sector V, she was still using an old radio and tin cans instead of a phone. She refused to accept her old age, even when Numbuh 1 pulled her false teeth out her mouth as evidence, insisting she could do anything they could do.
Biography[]
Early life[]

Lasso Lass in her youth
Lasso Lass formed the Cowboy Kids Club with John and Six-Shootin' Timmy, and their trusted horse, Clip Clop. From their secret treehouse, they fought adults on behalf of the kids in their town without any knowledge of the Kids Next Door.
But in their teens, the group split up after Lasso Lass went to prom with Texas Tommy instead of Timmy, due to Timmy starting to lose his hair at fourteen. But while John and Timmy left, Lasso Lass and Clip Clop kept the club active and blamed their departure on them growing up.
Meeting the Kids Next Door[]
Lasso Lass pulled Sector V up into a tree while they were being chased by Mr. Wink and Mr. Fibb, from whom they hade stolen a dome owned by Mr. Fibb. She then dropped the group of kids when Mr. Wink and Mr. Fibb launched rockets at them, resulting in them passing out and dropping the dome. She brought them back to her secret treehouse where she introduced herself and the Cowboy Kids Club. Lasso Lass demonstrated her old equipment for the kids and told of her continuous fight against adults, but Numbuh 1 still insisted that she could not fight adults when she was an adult. Unwilling to see herself as a grownup, she and Clip Clop forcibly joined Sector V on their mission to retrieve the dome from Mr. Wink and Mr. Fibb, but they both got captured by the villainous duo. She called to the treehouse for help and Sector V responded by modifying the treehouse into the B.A.R.N.S.T.O.R.M.E.R. and attacked Mr. Wink and Mr. Fibb. Their attack failed as well and they got tied up to hang over a small pool of lava next to Lasso Lass. While hanging upside down, Mr. Fibb opened the dome and put on his tupé, which made Lasso Lass recognize them as her old teammates, John and Six-Shootin' Timmy. She quickly fell in love with Timmy again, much to his dismay, and chased after them into the sunset (Operation: C.O.W.G.I.R.L.).
Trivia[]
