Numbuh 4 (Wallabee "Wally" Beatles) is a handsome 10 year old slender boy. He is also a Hand 2 hand combat expert at Sector V.
Wally is easily noticeable by his blonde hair with its bowl-shaped cut. He wears an orange hoodie sweater and blue jeans. His eyes, like almost the entire Sector V, are not always visible. He is also the shortest Sector V member, for which he is picked on a lot (for example, Numbuh 5 called him "sport" in [[Operation: M.A.T.A.D.O.R.]]). Another identifiable trait is his Australian accent. He is much larger than his brother Joey Beatles.
He also harbors a most obvious crush on his team mate, Numbuh 3.
Numbuh 4 is described as the team's bravest, toughest, strongest, fiercest, wildest, most adventurous, dangerous, courageous, and possibly the best fighter in Sector V. He is also the most impulsive, brash, hot-headed, arrogant, ignorant, and harshest of the team. As a result, it is stated in Operation: F.U.T.U.R.E. that his parents would send him to military schools, but he would always bust out. In Star Wars, He dressed as a Luke Skywalker (Jedi Knight) because both have blonde hair.
Season 7 Edit
