Ok. So here's an idea I'm going to try and flesh out.

Vector Sigma - Multiversal Super Computer with the ability to imbibe life or a spark into a Transformer.

Key to Vector Sigma - The activation key for Vector Sigma. Also has the ability to use a strange energy to transform matter into lifeless metal. (One would then postulate that Vector Sigma would then bring that lifeless metal to life, if that was the idea behind the duo of pieces)

Transmetal Driver - Datasphere for collection of information. True purpose unknown but also a holder of strange power, shows signs of a conciousness of its own. Reinstilled life into Blackarachnia after her spark was extinguished by Tarantulas's shell program counter-measures.

What if the Transmetal Driver, which I like to think Megatron stole from the Metal Hunter base when he was in command of it in Season 2 (which gives him plenty of time to test and alter it before its appearance in Feral Scream Parts 1 in season 3) was a Vok version of Vector Sigma.

We know the Vok seeded worlds with both energon and life, what if this little device, and others like it, is how they did it?

Instead of turning matter into metal, it takes it one step further and turns metal into Transmetal, the Vok's prefered medium of construction.

Thoughts?

(I don't profess to be a G1 expert, my research into Vector Sigma and its key is whatever I can read online.)
