So this is it then, huh? You're leaving us. (Numbuh 1: Wally, it's not like that.) Yeah, I know, I know. You gotta go save space kids up in Canada and stuff, but what about us here on Earth?! We need you, too, you know! (Numbuh 1: I guess the Kids Next Door think they need me more out there.) Yeah, well, if you need any help, you'll call, right? 'Cause you know we'll come running, right?! (Numbuh 1: Of course I know. You take care, okay?) Yeah. See you.
~ Wally's goodbye words to Nigel.

Wallabee "Wally" Beetles a.k.a. Numbuh 4 is one of the four deuteragonists of 2002 animated series, Codename: Kids Next Door. He is the brash and impulsive hand-to-hand combatant 10-year old Australian boy of Kids Next Door Sector V. He is best friends with Numbuh 2 and his crush, Numbuh 3, whom he would finally acknowledged their feelings and marry in the future.

Wally is arguably one of the two most popular characters of the show (alongside Kuki Sanban), often topping the polls of fans choosing who their favorite KND character is.

He was voiced by Dee Bradley Baker, who also voices Klaus Heisler in American Dad!, Perry the Platypus in Phineas and Ferb, and the Clone Troopers in the animated Star Wars franchise.

Physical Appearance[]

Wallabee has blond hair, with a bowl-shaped cut. He wears an orange hooded sweater, blue jeans and white sneakers. His eyes are not always visible, although it is revealed in Operation A.F.L.O.AT. that his eye color is green.

Abilities & Skills[]

His most noteworthy trait is his immense bravery, indomitable willpower & impressive strength, being able to not fear virtually anything or any foe.

Despite his slightly lowered intelligence, his natural strength, resilience & mobility is far much more developed than normal children or most adults. This combined with his immense martial arts skills, makes him capable of defeating five trained operates from the negative universe, who are far more ruthless than him. These physical attributes make up for his slightly low IQ. However, he was shown to have intelligence occasionally, while also being cunning as he has common sense.


Numbuh 4 is a unique and complex character from the popular Cartoon Network show 'Codename: Kids Next Door'. With his orange hoodie and blonde hair, Numbuh 4, or Wallabee Beatles, is instantly recognizable. He might come off as someone who is brash and impulsive but he has a good heart and is willing to do whatever it takes to protect those he cares about.

Numbuh 4 may be short-tempered and egotistical at times but he is also incredibly brave, showing no fear in the face of danger and never backing down from a challenge. His loyalty to his friends is unshakable and even though he isn't the sharpest tool in the shed, he is willing to take risks and face his fears in his fight against the evil adults.

At his core, Numbuh 4 is incredibly caring and kind-hearted, willing to put himself in danger to protect those in need or save the day and always looking out for his friends. He truly believes in justice and is always looking for ways to make the world a better place.

Overall, Numbuh 4 is an endearing and wonderfully complex character who shows his true colors when it really matters. He may be impulsive and egotistical but his bravery and loyalty shines brightly and makes him an irresistible hero.



  • Just like the rest of Sector V, Number 4's real name is a number pun. The Beatles were a 1960s British boy band that consisted of four members - John Lennon, Paul McCartney, George Harrison and Ringo Starr.
  • In the episode of Operation: M.I.S.S.I.O.N, Numbuh 4 serves as the main antagonist, and he releases the villains like, Stickybeard, Count Spankulot, Soccer Mom, Mr. Boss, and Toiletnator from the Arctic Prison, so they went to the Pinhead Lanes Bowling Alley to beat Sydney in bowling.
