Numbuh Four (real name Wallabee "Wally" Beetles) is a character from Codename: Kids Next Door. He is the hand-to-hand combat expert of Sector V and comes from Australia. He has two parents that always look at the bright side, and has a baby brother in his family. His personality and slightly dimwitted mind often gets him tricked or suckered. But despite this, he's got a strong sense of determination and never gives up in a fight. He hates all girly things and fears swimming. Despite this, he has a hidden crush on fellow KND operative Numbuh Three (or, at least, hidden to her). The Toiletnator is also his long lost uncle.

Numbuh Four
In the Past, he's at Mount Blackhead with Numbuh Three. He helps the player find and take on Fusion Toiletnator and also hands out missions. During the mission for the Mac Nano, he was much needed help when the player tries to recover Mac's bag from Fuse's monsters only to realize a Gooby Trap was set inside. His Fusion lies within the Dinosaur Pass Infected Zone found within the Darklands. The Fusion Numbuh Four secret lair is outside the Infected Zone near the Really Twisted Forest.
