Big Looker Storybooks

Not long after the eruption of a nearby volcano, the Decepticons attacked Kimball's nuclear plant. They drained all of the power from the plant, plunging the city into darkness. Luckily this was witnessed by Sparkplug and Spike, who were heading back to the city in Hound, and it allowed them to warn Optimus Prime of an impending Decepticon attack on the Ark.

Notes

• In "Decepticon Hijack", the Autobot Base is said to be located in Oregon, so we can assume that Kimball is most likely also located there.
