"After the DECEPTICONS fail to steal the superfuel that has been given to the AUTOBOTS, their leader decides that they need their own land-based forces. After some choice thefts and modifications with Cybertronian technology, the STUNTICONS are born. But as powerful as they are, they lack the spark of life. And the only place to obtain it is Vector Sigma.

The AUTOBOTS learn of the DECEPTICONS’ plan, and realize that the newly created STUNTICONS will need to be taken to Cybertron to be given true life. In order to counter this, a group of AUTOBOTS returns to their home world to create their own sky-worthy forces.

Both groups arrive at Vector Sigma nearly simultaneously, and the AUTOBOTS and the DECEPTICONS bring life to their new allies in time for a major showdown. On one side, MOTORMASTER and the other STUNTICONS rise to life, while on the other, FIREFLIGHT, ALPHA BRAVO, and the AERIALBOTS stand tall, fighting for control of the key to Vector Sigma!

The battle starts to go badly for the DECEPTICONS, but as things look grim for them, the STUNTICONS join together to become the colossal MENASOR! With the increased firepower of their gigantic foe, the tide begins to turn against the AUTOBOTS.

Will the AERIALBOTS be able to defeat the vicious STUNTICONS? Or will MENASOR and the DECEPTICONS drive the AUTOBOTS out of Vector Sigma? Find out in TRANSFORMERS Legends - “The Key to Vector Sigma, Part 1”!"


Despite the impressive power of MENASOR, the DECEPTICON forces are routed by the AERIALBOTS, though they are still able to retain the key to Vector Sigma. Cursing their foes, the DECEPTICONS retreat to Earth, content in thinking they have a new weapon that is unmatched by the AUTOBOTS.
