Binky is Death's steed, named so by Death because it is "a nice name". He is a living horse; Death tried a skeletal steed, but kept having to "stop and wire bits back on". Death also tried a fiery steed, but it repeatedly set his barn and his robe on fire.

Binky is rather more intelligent than most horses and is pure, milky and white (it is noted in some novels that Binky is an exception to the biological rule of "grey" equines). He can fly by just creating his own ground-level, as well as travel through time and across dimensions, sometimes leaving glowing hoofprints in his wake, but is in all other respects a perfectly ordinary horse. He is well-treated, and loyal to his master and Susan. His shoeing is done by Jason Ogg, the Lancrastian blacksmith of mythical skill. Binky is not immortal, but while in Death's service does not age. Binky gains part of his powers by sharing one of Death's qualities: he's so much "realer" than ordinary things such as walls, great distances, or time that he can simply ignore them.
