It was hard to believe, Unicron, the Chaos Bringer himself, had fallen in love with one of the humans he accidentally created, Sparkplug Witwicky....and it didn't feel bad. Disguised as a man named Arther Urosas, Unicron managed to seduce Sparkplug, and get close to Sparkplug's son, Spike, and adopted child, Chris. They were happy with their new second father, especially Chris, who was actually Unicron's creation, but he wouldn’t mention that.
