Energon Volant Accumulator

The Energon Volant Accumulator is a human airship from the Energon portion of the Unicron Trilogy continuity family.

The Energon Volant Accumulator, often shortened to E.V.A or Eva, is a plane created by Alterenergy. Its function is to collect the Energon vapour that would otherwise be lost to the atmosphere in special capacitor cells. While not designed for combat, it is equipped with various pieces of weaponry to get through hostile areas if needed.

Rad and Alexis were rescued from a large Terrorcon attack on Los Angeles by the arrival of the Autobots, but Rad realized this was only a temporary reprieve, as the Autobots were expending their Energon resources rapidly. Knowing of a way to help them, Rad contacted Carlos at Alterenergy and instructed him to prepare Eva for immediate takeoff. Multiplicity, Pt. 3

Rad left a few minutes later in E.V.A., taking out two Terrorcons with it to start, while his friends worriedly monitored his progress from the Alterenergy facility. Multiplicity, Pt. 4
