Fiction

Ask Vector Prime

After Galvatron used Decepto-Packs to conquer and enslave humanity, he directed their efforts towards building armies of Zod drones. These were used to conquer a sizable portion of the galaxy, until the Quintesson Pan Galactic Co-Prosperity Sphere was forced to intercede. Ask Vector Prime

Notes

Zods were, of course, first introduced in the Challenge of the GoBots cartoon. Cy-Kill's plan in the five part pilot was essentially identical to Galvatron's plan in Primax 185.0 Beta; humanity was enslaved and used to build an army of Zods, which were then to be used to conquer Gobotron.
