Created by YouTube user J16FOX, the Vagineer, one of the first and most famous "TF2 monsters", is the Engineer with a heavily distorted facial expression, making his mouth look like a vagina (created by using the Face Poser in Garry's Mod and setting different values to higher/lower levels than the TF2 faces are used to). Vagineer usually appears as a villainous character in Garry's Mod videos.

Vagineer's sounds are reversed Engineer voice lines, and it is usually seeing grunting at other characters. Vagineer has a large arsenal of attacks, including launching his arms to grab distant enemies or objects, propelling its legs like rockets and becoming invincible. Vagineer is also capable of regenerating body parts and turning other people into "Vagi" versions of their characters.

Vagineer is viewed as a demigod-like monster, rarely being defeated by anyone, and when that happens, Vagineer usually regenerates and strikes again. Because of his popularity, many other creatures were created and are usually portrayed as Vagineer's enemies, but none of them are as famous as him.
