He gave the Rescue Bots their mission and mainly appeared via a view-screen, appearing physically in the first episode and then in the first-season finale, where his truck mode was seen for the first time on screen. He then returned, with or without Bumblebee, many times throughout the second and third seasons as a recurring character. In the episode "Land Before Prime", Optimus Prime arrived on Wayward Island to help the Rescue Bots. He scanned Trex as a secondary form where gained a Tyrannosaurus form, making him a Triple Changer, though he stated that scanning anything techno-organic might have unpredictable results. While he lost control of this "Primal Mode" at first, the Rescue Bots determined that his loss of control was due to low Energon reserves, and were able to replenish his energies and restore him to normal using an Energon patch. At the conclusion of the third season, Optimus helped his old friend, High Tide, along with the new recruits, Blurr and Salvage, save Griffin Rock and subsequently sent Heatwave and his team on a new mission to use the island as "testing place" to reveal their true identities as aliens.
