There is a reason I'm just calling them Units.
Its kinda been established that each of Nexus' 5 Units changes after he separates each time.
Think about it, neither Clocker nor Mainspring have flight modes due to being Velocitronian. Also it doesn't make sense for Pinion or Cannonspring to have flight modes due to being Junkions. Chaindrive is questionable. This results in Nexus' not having flight Units.
However Fan Publications version has flight Units. (But this could be the result of just wanting to reuse only Supirion Maximus and Bruticus Maximus parts).
While I am trying to paint them close to the pictures of him, not everything works out. I should have grabbed 2 Universe Topspins so I could have 2 jets. However one can think of my version of Nexus Prime as either his first or next forms.
But for names of individuals one can say:
Impactor = Core Unit = Heat Wave
Topspin = Jet Unit = Skyfall
Whirl = Helicopter Unit = Breakaway (to many Topspins)
Twintwist = Tank Unit = either Landquake or Cannonspring
Roadbuster = Car Unit = either Chaindrive or Mainspring
Immaturity is shown by not trying to understand others, but by judging others.
