Nova-X3J was an advanced prototype computer that was being developed by Pogo Computer Systems. It enabled users to access the internet without wifi and also had unlimited processing. With the advanced computer, this greatly enhanced the damage and influence of the sourceror's hacks.
The sourceror tasked Megabyte to create a distraction at the Pogo Computer Systems with the ultimate goal of stealing the protytpe while the staff were too busy with the situation in cyberspace.
After Adam Carter sacrificed himself and his villainous persona, the DIS found the truck that the sourceror used, but the Nova-X3J was nowhere to be found.
