One of the largest discrepancies between masterforce and the series that came before it (Specifically S3/2010 and Headmasters) is that the level of technology seemed to have travelled back in time to 'modern' technology. Very little is futuristic, when the prvious shows were firmly in the sci fi camp. the question is why? (in an in-fiction way) I believe that it ties into the fact that the Cybertronians essentially left Earth at the end of Headmasters, and that they took the means to power the futuristic technology with them. For society and tech to have made such a massive leap between the mid 80s and 2005 alternative energy would have been a major influence along with the 'alien' help from the autobots. That energy would have been Energon. However, I believe the means to create energon would have been retained by the Autobots: while they would happily supply the means to produce it they wouldn't give up the secret, and took it with them into space, forcing Humanity to revert to the old ways in the years to come, which is why we see a very present day level of technology in Masterforce.
