Praised as a Valve creation, the new Special Infected known as the "Charger" actually comes from the mind of a Steam forum user by the name of ms255, in a thread he created back in December 2008. Fast forwarding to half a year later, videos and press coverage of the sequel are released, and lo and behold, in comes the monster to L4D2 with a name even proposed by the original creator: The Charger. However, his reaction is not what you would expect from someone who had their idea put into a video game, as he is in fact, very dismayed.
