Although Jem ranks among the top generals in the Men In Black, there are no legal records of him ever being an Imperial Knight. It is rumored that he instead worked as an independent on Mars during the rebellion before joining up with the MIB. Owning a Dreadlock, he made a living through the salavaging and selling of HERC components that had been strewn across the battlefield. It was easy for him as he possessed knowledge on the stealth capabilities of cloaking systems and jammers, which helped him avoid conflict as he scraped up the destroyed bases.

How Jem became part of the Men In Black in the first place is a story disputed by many of the recruits, however only the top generals know the truth about his backstory. Of the stories, the most popular involves another MIB official known as Victor, whom is believed to have been close friends with Jem before he was introduced to the Men In Black. Apparently, just before the cybrids launched their assault on Mars in 2830, they were reunited in a Martian tavern during an undercover reconnaissance mission. Information about the MIB had been leaked, but Victor helped him get into the MIB. As the evacuation took place, the two were directly spirited away to the MIB headquarters on Titan. Since then, Jem, under the callsign "Powio", quickly climbed the ranks of the squadron through his expertise in R&D and military tactics. Somewhere along the line, Victor mysteriously vanished, leaving only Jem to take his place.
