Wallabee Beatles a.k.a. Numbuh 4 is one of the four deuteragonists of the 2002 animated series, Codename: Kids Next Door. He is an Australian-American Kids Next Door Operative in Sector V.

Why He Rocks

 * 1) He’s short-tempered and fighting-prone one of Sector V, with his attitude and fighting skills.
 * 2) He’s an incredibly skilled fighter, along with Numbuh 1, one of the greatest examples of his strength is defeating Numbuh 274, the greatest KND operative of his time.
 * 3) Despite his tough attitude, he deeply cares for his teammates, as seen in Operation: P.O.O.L.
 * 4) The same episode mentioned above shows that he has some intelligence, such as sensing imposters, like when looking into Negative Numbuh 3’s eyes.
 * 5) Numbuh 4 has a passion for sports, as shown in Operation: F.O.U.N.T.A.I.N.
 * 6) Despite getting annoyed by his younger baby brother, Joey, he cares about him and tries his best to be a good big brother, such as looking for him and making sure he’s ok in Operation S.A.F.E.T.Y.
 * 7) He has a great friendship with Numbuh 9, and even shed tears when Numbuh 9 was being decommissioned in Operation: M.A.U.R.I.C.E.
 * 8) He is shown to care for and respect Numbuh 1, as in Operation I.N.T.E.R.V.I.E.W.S., he was the most devastated when Numbuh 1 joined the Galactic KND.

Bad Qualities

 * 1) His rude attitude and stupidity set a bad example and encourage toxic masculinity.
 * 2) It’s revealed that sports is the only thing he’s good at besides fighting, which is sad.
 * 3) He has little concern sometimes for people he barely knows, like Leaky Leona in Operation F.O.U.N.T.A.I.N. But he does have a change of heart after knowing the Delightful Children from Down the Lane caused Numbuh 1’s baldness, and saved her from facing the same fate.
 * 4) Because of his stupidity, he follows Numbuh 1's nonsense theories without question. He even took advantage of it just to destroy a piano his mom ordered for him.
