Fasttrack is a semi-autonomous armored interceptor under the control of the Decepticon Scorponok.
Marvel Comics Continuity
Fasttrack was among the Decepticons under Scorponok's command. They were ambushed while leading captured Autobots on a death-march to Template:Tooltip smelting pool. Fasttrack seemed caught off-balance balance by the attack, and was among the first to flee the scene once the retreat was sounded.
The comic's mistake-riddled coloring seems to indicate Fasttrack was the fleeing Decepticon Scorponok called a coward after pointing out they were badly outgunned. The robot mode was shown was Blot's however- a mistake also not uncommon in the Headmasters comic...
Fasstrack had a character model prepared for The Rebirth, the mini-series which ended Generation 1, but never actually appeared.
Fasttrack may have been slated to appear before Rebirth was cut from 5 parts to 3
An army of Fasttracks (called the Guardminders) appeared in a battle in space.
Alsomt all of the Guardminders that appeared had the color scheme of the Fasttrack that came with Scoropnok. The one exception, who appeared to be the leader of the army, was colored like the Fasttrack that came with Black Zarak.
