The Key to Vector Sigma, Part 1 | Transformers: Generation 1 | Season 2 | E39 |

With the Stunticons (Motormaster, Dead End, Breakdown, Drag Strip, and Wildrider) at their disposal, the Decepticons hope to crush the Autobots once and for all. Problem is, the Stunticons will always be lifeless pieces of metal without the Cybertron-located Vector Sigma. Finding Vector Sigma isn't really the challenge. Finding the Key is. Upon learning that something is up, the Autobots quickly jump into action and search. It is practically a race to see who will be the first to find the Key and use it to access Vector Sigma.
