Transformers 1984 Episode 57 - The Key to Vector Sigma, Part 2 Episode Title:The Key to Vector Sigma, Part 2.Episode Description:With the Stunticons operational and the Key in hand, the situation is definitely in the Decepticons' favor. Most severe of all, the Key will allow Megatron to eliminate all organic life on Earth replacing it with technology. The Autobots need new allies the Aerialbots (Silverbolt, Air Raid, Fireflight, Skydive, and Slingshot) and quickly. Being unable to use Vector Sigma, though, complicates that idea. It will take sacrificing one life to give the Aerialbots' theirs. This episode reveals the Aerialbots and Stunticons combined modes: Superion and Menasor. On top of that, despite his status, Silverbolt has acrophobia.
