Transformers Generation 1 Season 2 Part 2 Guide
The following is my personal opinion.

In the second part of season 2, we have a few 2-part episodes, and we see the introduction of more Autobots, many of them out of nowhere.
There has been a long debate in the Transformers community over where they came from. Were they all this time unconscious in the ark and, for unknown reasons, reactivated? Were they active, but we did not see them? Or did they just arrive on earth? For me, the answer has always been simple: they just arrived on earth, and I will explain why below in spoiler in case someone has not seen the episodes. I know it is an old kids show from the 80s, but younger people might not have seen it.

!So I believe the new Autobots arrive on Earth from Cybertron sometime during the events of the second season. Most likely Omega Supreme brought them to Earth. The problem most people have with this theory is that the new Autobots in the episodes Desertion of Dinobots suffer the same side effects from Cybertonium depletion as the season one Autobots. Who have been on earth for millions of years. And since the new Autobots were suffering as the old Autobots at the same time, they couldn't have been on Cybertron.
This logic is, in my opinion, wrong because just because they were on Cybetron is not enough to have enough Cybertonium. The episode clearly shows that it is something that has to be mined and consumed the same way as Energon. And the Decepticons are in control of the Cybertonium mines, so the Autobots have no access to Cybertonium. Which would explain why they suffered.
So for me it all makes sense unless I am missing something.
