...any of the various seconds-in-command were to take control, following the death of their Megatron or Galvatron? Starscream - The Decepticons still engage in ludicrous plans to obtain energy, but they are foiled much more quickly due to Starscream's rashness and cowardice. Eventually Starscream abandons the Decepticons, as he did the Combaticons, and does something stupid in a solo venture that gets himself killed. Cyclonus - The Decepticons conquer Cybertron. No really. Scorponok - The Predacons don't really do ANYTHING, as Scorponok seems to lack the not only the intelligence or competance to lead, but also the ambition to do anything that he isn't told to do. Leadership most likely seized by Blackarachnia or Tarantulus. Tarantulus - BW Megatron's second SIC. Would most likely divert all his newly acquired resources to killing all Cybertronians and the Vok Sky-Byte - Poetry jam. As I am unfamiliar with the Unicron Trilogy, and Animated Megs lacks a second due to the ousting of Starscream, I'll end my own speculations here.
