Notes

• An abandoned OTFCC 2004-exclusive redeco of 2001 Robots in Disguise Rail Racer would have been named "Dominus Trannis". Since one of his components would have been Astrotrain, the combined form likely wouldn't have resulted in being the same character as the original Trannis, but his name was indeed the inspiration. The other components would have been named "Steamhammer" and either "Loco" or "Cowcatcher." Both Steamhammer and Cowcatcher went on to inspire names for later official toy releases.
