I was thinking about this last night driving home from work, The transformers have two distinct tag lines, 'More than meets the eye' and 'robots in disguise' The difference is that for the first these are vehicles or robots that are more than what they appear to be. They can use the ability to change forms to become more powerful, fly or whatever and really separate as being transformers. The second has a more espionage feel to it. The Transformers can blend in with the vehicles or animals on the host planet. This would really serve no purpose on Cybertron, where every one has an alt mode, or if they have been accepted as transformers on the particular plant as being able to change forms. (re: speed planet) Throughout the 26 years, different series have had different focuses. Gen 1 Was a lot about the disguise, but after the movie, it become apparent that they were not trying to hide anymore. BW was a little of both for the first season then again reverted to more powerful alt modes over stealth RID was really based on the autobots living on earth undetected. Armada- little of both Energon - No mention of blending in with earth. Cybertron- Blending in on earth, no where else. Which do you prefer?
