Spoilers ahead! If you have not watched the 5 parter, then click the back button now. Do not read on. So part 5 showed Megatron being caught in an energon explosion as big as ( if not bigger ) than the one that we saw when we last saw Cliffjumper. Most speculation has been that Cliffjumper is dead for good since there is no way to survive a blast like that. Problem is, that means Megatron is dead too. Since they are not gonna kill Megatron off in the opening of the show, we can safely assume he survived. Also, the Autobots believe he is dead, which means there is no known means by which Megatron could survive the blast. The only variable is the Dark Energon. So that has to be the element that allows him to survive. I think it's safe to assume that Cliffjumper ( zombified at the least ) is still kicking. So what do you think?
