Universe Autobot Blaster Classic Series:

Working alongside his friend Perceptor, Autobot Blaster has organized a series of resistance cells to fight against even more organized Decepticon attack squads. He is the communications & data expert, maintaining detailed internal records of all personnel & mission reports. In vehicle mode, he can travel faster than light speed to hand-deliver orders of information, or emit high-speed encoded radio-bursts up to 20,000 miles. Together with Flashback, he is also a powerful warrior. Both partners are always more than ready for a fight.

Note: On the box, his partner is Blockrock not Flashback. Nice going Hasbro.

Universe Decepticon Heavy Load Classic Series:

Back on Cybertron, before the war, Decepticon Heavy Load was a brilliant chemist & engineer, specializing in Optimizing fuel mixtures to increase the energy efficiency of all mechanoid life. Repeated exposure to toxic chemicals over hundreds of years slowly degraded his cognitive systems, turning him into someone none of his friends recognized. As his brain module rotted, he grew more withdrawn, & began to focus more on his failed experiments - the ones that poisoned his test subjects. Now, he develops poisons & corrosive bombs for whichever Decepticon gangs can pay his fees, & continues his experiments on helpless Autobot captives.
