Mark Morgan is a minor villain from the original G1 Transformers. He is Jessica's father & a scientist who hates Transformers regardless of faction & serves as one of the (former) secondary antagonists of the 2-part season finale of Season 3 "The Return of Optimus Prime". 

G1 Transformers

Mark Morgan was in charge of sending his daughter Jessica & his colleague Gregory Swofford across the universe to conduct tests on experimental heat-resistant alloy near a star. The mission was a success, but however, Jessica & Swofford home two other rediscoveries: Optimus Prime's body & a sample of red spore.

In the laboratory, he & Swofford tested the red spore on two lab rats, discovering its hate inducing properties. He was about to dismiss his daughter's warning of the spores getting loose when their lab lab was suddenly attacked by the Decepticon dragon combiners, the Terrorcons, who came for the heat-resistant alloy. Morgan was about get crushed by falling debris, only to be saved by his own daughter, who was crushed instead thus crippling her. The Technobots soon arrived, fought off the mechanical dragons & saved Jessica. Despite the Autobots' best efforts, he blamed the attack on every Transformers. Morgan then conspired with his colleague Swofford into using Optimus Prime's body & the Hate Plague to destroy every Transformers regardless of faction.

As the doctors tried to save Jessica's life, Morgan worked hard to revive Optimus, only to fail as well. He soon visited his daughter, only to his horror as she is surrounded by Protectobots, who gave her mechanical prosthetics. Morgan paranoidly claimed they have turned his daughter into a cyborg & took her home immediately. Unable to revive Optimus, Morgan & Swofford tried to melt the Autobot leader's body, only to be stopped by his own daughter, who tearfully pleaded. Instead, he decided to use his own daughter, who is an Autobot ally, to lure the Autobots into their lab. 

After Jessica alerted Rodimus, the Autobots soon rushed into her father's lab with caution. Ultra Magnus & the Aerialbots, however, fell into Morgan's trap & ended up being the first infected victims of the Hate Plague. This soon started to infect other Autobots in the area as well. Morgan himself threw a canister of Hate Plague spore on Rodimus but missed. The Hate Plague soon spread on the entire universe as it infects not only Transformers but as well as humans & various lifeforms across the universe, presumingly including Morgan & Swofford as well offscreen.

After the Hate Plague was wiped out by a revived Optimus Prime, Morgan was soon freed of the infection. He apologizes to Optimus, who in turn pardons him on behalf of his daughter.


  • Alongside his colleague Swofford, they are both similar to James Savoy as they both hated Transformers regardless of faction due to being the cause of their loved ones' demise. Unlike Morgan & Swofford however, Savoy never redeems himself and has Yangire-like qualities that both Morgan and Swofford lacks.
  • Morgan is very similar to Hiroshi Sato as they are both important figures who racially despise a certain powerful race for being the cause of their loved ones' demise & are both fathers with a daughter.
