Bloaters (walkers)

"I think I need a bath"

- Marcus to Jacob about dealing with a Bloater

A Bloater, a.k.a Rotter, is a Freak-type walkers encountered in The Walking Dead: Decay. Unlike any other walker types, however, Rotters still pose a threat even after elimination, thanks to the ability to release a toxic gas that can get survivors sick and kill them over time.

Information
Rotters can be difficult to spot when among other walkers. They are somewhat taller, grey and slimy, with spindly, wasted limbs and a grossly distended abdomen. They are clad only in a loincloth-type garment which is often hidden under their swollen bulk, and move in an unsteady, tottering shamble.

In a mix of other "normal" walkers, they can blend in with other overweight walkers at a distance simply by being hidden by the bulk of its fellows. In this case, only their greater height is a distinguishing characteristic, although by the time a survivor is close enough to make this assessment, it may be too late.

Trivia

 * It may have been a bloater that got Pastor William sick and indirectly killed him.
 * Alan killed Pastor William for being sick and being a "threat"
