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 teammate, Numbuh 3.
Personality[1]Edit[]
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. He is close friends with Hoagie and has a crush on his teammate, Kuki, who is his close friend and teammate who returns his feelings. He ends up marrying Kuki in the future. There are few amongst the KND that can match him in hand-to-hand combat, and even fewer who can compete with his bravery. Numbuh 4 is also known for his apparent lack of intelligence, preferring to simply beat up any and all obstacles in his way.
