Arcee serves as a dedicated Autobot warrior within the *Transformers: The Headmasters* continuity. Stationed at the Autobots' secondary command post on Athenia during 2011, her primary duties involve defensive operations and critical missions. When Vector Sigma destabilizes, threatening Cybertron and enabling Decepticon attacks augmented by new Headmaster warriors, Arcee holds position on Athenia alongside Hot Rod, Kup, Blurr, and the humans Spike Witwicky and Carly. This team secures the command post while other Autobots engage directly on Cybertron. Her responsibilities extend beyond base security. Arcee actively joins the conflict against Unicron as the planet-eater attempts self-reformation using his disciples' bodies. She fights alongside both Autobot and Decepticon forces in this unified effort to halt Unicron's rebirth. During this event, she witnesses Optimus Prime utilizing the power of the Oracle to ultimately defeat Unicron and imprison him at Triple Z Point. This continuity diverges significantly from other portrayals regarding her relationship with Daniel Witwicky. Unlike the U.S. cartoon conclusion (*The Rebirth*), Arcee does not undergo binary bonding to become a Headmaster with Daniel within the Japanese timeline. Consequently, her combat abilities rely solely on her inherent skills as a Cybertronian warrior. She transforms into a Cybertronian hover car, leveraging superior speed and agility for tactical advantages. Her proficiency encompasses both ranged combat with twin blaster pistols and formidable hand-to-hand engagements. Arcee demonstrates consistent compassion, particularly towards organic allies like humans. This protective instinct manifests during missions, aligning with her established role as a guardian figure in other continuities, though without the specific maternal bond with Daniel seen elsewhere. Her combat effectiveness remains undiminished, showcasing her capability as a frontline fighter. Her background as a close associate of Hot Rod carries over; she maintains her position among Rodimus Prime's key soldiers following his ascension after the Unicron War. While specific personal story arcs or deep character development within *The Headmasters* series are not detailed in available sources, Arcee fulfills a steadfast role within the Autobot ranks. She contributes to major battles and strategic operations from the series' inception ("Four Warriors Come out of The Sky") through its concluding episodes ("The Final Showdown On Earth").
