Transformers Universe Voyager Decepticon Heavy Load
Back on CYBERTRON, before the war, DECEPTICON HEAVY LOAD was a brilliant chemist and 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 As his brain module rotted, he grew more withdrawn, and began to focus more on his failed experiments - the ones that had poisoned his test subjects. Now, he develops poisons and corrosive bombs for whichever DECEPTICON gangs can pay his fees, and continues his experiments on helpless AUTOBOT captives.
