Megatron is a central figure in the conflict on Elementros, arriving alongside Optimus Prime. He commands dinosaur-type Energy Beasts, such as Captain Volca, a Tyrannosaurus-type Transformer possessing Flame Energy (fire attribute). Utilizing "Wildocking" (also referred to as "Wildcoking" or "Wildooking"), Megatron combines with these beasts, merging their elemental powers with his own capabilities. This gimmick enables the combined entity to wield the specific elemental energy of the docked beast. He transforms between a robot form, where he wields a fusion cannon as his primary weapon, and a vehicle mode. His design facilitates combination with the Energy Beasts during Wildocking, typically forming the core component while they attach as limbs or armor. Megatron's relationship with Optimus Prime is defined by rivalry and conflict. Upon arrival on Elementros, he quickly becomes antagonistic towards Optimus, initiating attacks. He leads the faction commanding the dinosaurs, opposing Optimus's faction allied with the animal-type Energy Beasts, driving the narrative's core conflict. The character's background prior to arriving on Elementros is not elaborated upon. His development across the media focuses on his role in the ongoing battles utilizing the Wildocking gimmick with his Energy Beast partners.
