Blot is a minor antagonist in the Transformers franchise, especially Generation One. The original version of the character was a member of the Terrorcons, a group of the Decepticons. He is considered the most disgusting Transformer, who leaks a foul-smelling lubricant. He is also brutish and dim-witted.
Blot made his first appearance in the late third season episode "Grimlock's New Brain", where he and the other Terrorcons assisted Galvatron in his scheme to raid Unicron's head for anti-electrons. They were initially successful but were beaten back by the arrival of the new Technobots. Blot and the others were given a featured role in "Money is Everything", employed by the Quintessons to recover a matter disassembler/reassembler which had been stolen by Dirk Morgan, which saw them again go up against the Technobots.
Blot was among the raiding party on Gregory Swofford's laboratory in "The Return of Optimus Prime". He was last seen in the concluding three-part miniseries "The Rebirth" as part of Galvatron's assault team against the Autobots on Cybertron.
He was voiced by the late Tony St James, who also voiced Brawl.
Blot was first seen in the Headmasters miniseries as one of the Decepticons who accompanied Scorponok to Nebulos. He was involved in the first battle with the Autobot Headmasters, joined the other Terrorcons in attacking a Nebulon resort and battling the Technobots, and was also present for the first battle with the Autobot Targetmasters.
He appeared in the regular comic during the Underbase Saga, by which point Scorponok's faction had traveled to Earth and ended up clashing with the locals Decepticons led by Ratbat. Blot was among the Transformers deactivated by the Underbase-powered Starscream.
The post-movie version of the character appeared in "Headhunt" where he was sent by Shockwave to make contact with the bounty hunter Death's Head. His attempt to convince Death's Head to go after Rodimus Prime out of pride fell on deaf ears, but offering him money was more successful. In "Time Wars", Blot and the other Terrorcons acted as Soundwave's back-up when he set up an energy-draining machine on Earth, only to have it wrecked by Kup, Arcee and Red Alert. They pursued the Autobots into the past and ended up becoming part of an alliance against Galvatron. However, they ended up fleeing the battle without engaging and returning to their own time.
