Chapter 1: A Ancient Artifact

Amidst their battle against enemy warlord Mega Tron shortly after they are found by their planet's life source, the All Spark, kind robot Optimus Prime and his crew, Ratchet, Bumblebee, Bulkhead, Prowl, Sideswipe, Sun Streaker, Mirage & Hound, fall towards Earth, where he steers their spaceship away from civilians before joining them in stasis. Half a century later, they wake up after a piece of a creature enters their spaceship and give themselves new vehicle modes. While Ratchet analyzes the piece, the rest of the crew goes to fight the creature. During the battle, Bumblebee earns the full trust of twin girls Sari & Slate Sumdac and their older sister Saga, who is four years older than the twin girls. They later get two more friends in Luxury and Meadow James, teen sisters who are four years apart in age and live with their parents, bakery owners Adelina and Ryle James, and paternal grandmother, retired restaurant waitress Talulah James, all three of who had recently told both the seventeen year old and thirteen year old they aren't humans, but sisterly robotic beings.
