Smoker

The Smoker is a type of infected in Left 4 Dead and its sequel, being a smoke emitting zombie that strangles survivors with its long tongue.

Features
The Smoker's main form of attack, other than clawing, is shooting its tongue out of its mouth, wrapping it around a survivor's throat, and reeling them in until either the Smoker is killed/damaged or the survivor is strangled to death. Also, when killed, a large puff of smoke excretes from the Smoker that causes nearby survivors to go in a coughing fit.

Appearance
In the first game, the Smoker is depicted of having an open olive vest revealing a white undershirt and blue jeans. With messy black hair and converses, the Smoker also has dark grey skin with bubbly tumors littering his body, especially its face, which is just a cluster of huge tumors. It also has its famous long tongue dangling out of its neck.

In Left 4 Dead 2, it looks completely different, having a navy T-shirt, dark blue jeans, and brown boots. Now, its skin is very brown with extremely huge tumors that takes up most of its face and sags down to its chest. It also has firm brown hair with several tongues cluttering its body, the locations being in its mouth (of course), two out of its shoulder, one out of its neck, and two out of its collarbone.
