Ok so we have twins like Sunstreaker and Sideswipe. and clones lets say Pounce and Wingspan, and Cloudraker and Fastlane. So what is the difference between the clones and the twins? Is the clone made after the one robot was created, therefore not really being twins? Then are they brothers? Also would you consider Eject and Rewind or Frenzy and Rumble twins? brothers? What about Runabout and Runamuck?
