While the majority of Prime's forces have moved to the front lines on Earth, several have remained on Cybertron to continue the fight there. Aside from certain exceptions (such as Elita One), the following Autobots are usually assigned to Cybertron except for special missions (ie, have players):
- Autobot Clones (Cloudraker and Fastlane)
- Deluxe Autobots (Roadbuster and Whirl)
- Female Autobots (including Arcee)
- Jumpstarters (Topspin and Twin Twist)
- Most movie Autobots, aside from Ultra Magnus (Blurr, Hot Rod, Kup, Wheelie, etc)
Basically, if the Autobot doesn't have an Earth-based altmode, they're probably on Cybertron if they don't have a player
Since most roleplay takes place on Earth, most Cybertronian characters with active players are assumed to be transfered to Earth for the length of time they have players. This list is for background characters and those that need to be temped for TPs.
