In his first appearance in the series, Optimus looks similar to the original Optimus Prime until he copies himself with a semi-truck and his design in robot mode changes. Soon after, he retrieves his Mini-Con partner, Sparkplug. The cab of his truck mode detaches to form Optimus himself, while the trailer transforms into a battle station mode operable by Optimus and several Mini-Cons. Optimus can also combine with his trailer to form a "Super Mode" robot that, when combined with Sparkplug, can fire a series of powerful lasers. Additionally, Optimus can combine with Jetfire and/or Overload in his Super Mode for additional power.
