His life between his creation by Unicron and the story is not known, like the other Horsemen. He was sent by Unicron to find the shards, since Cybertron wasn't dying fast enough. With the aid of the other 3 Horsemen, he collected(stole)12 shards, and was prepared to get the last from Thunderwing (TNBW), who put up enough of a fight to knock him unconsious. He was killed later on Alpha V when Zero and Thunderwing removed his planet shards and powered up. They then beat him to death(how ironic).
Death is equipped with a weapon aptly called the 'Death-ray.' On full power, it can shoot through a planet. Even on its lowest active power setting, it can easily kill another Transformer. It fortunately fires very slowly, and he can only use it on full power under a planet shard's power. He is equipped with a rapid-firing blaster built in to one arm for anti-personnel combat. He is equipped with a scythe on one arm that emits an energy field for enhanced cutting power. In beast mode, he can make use of a variety of missiles and bombs. He has no known physical weaknesses, but is not designed with personal combat in mind. He is, as such, not as skilled in it as the others.
Desth is black with purple accents, and red eyes. His head looks like Galvatron's
Behind the Scenes
Death doesn't ride a horse. The original idea for him was for him to be a dark clone of Vector Prime.
