X-Car, identified as Crosswise in select international adaptations, serves as the science officer of the Autobots’ specialized Spychangers unit. Specializing in gravitational field manipulation, he wields a gravity-beam gun to levitate objects and adjust localized gravity, tactics applied in high-stakes operations like redirecting volcanic eruptions to protect populated areas. Activating his Super Mode, he modifies his own gravitational pull to achieve flight for rapid response or tactical repositioning.

As lead technician, he manages equipment maintenance and performance upgrades for fellow Spychangers, alongside pioneering research into Spark Engines—core components amplifying their operational capacities. His analytical skills extend to countering enemy tech, including devising strategies to dismantle Megatron’s Mega-Laser Cannon via the Global Space Bridge infrastructure.

Expanded Japanese lore positions him within a Dimensional Patrol unit defending multiversal stability. During clashes against Scourge’s Combatrons and the transdimensional entity Devil Gigatron, he participates in direct combat operations aboard the Neo Brave Maximus warship, disrupting hostile advances. Additional missions involve countering occult incursions, such as dismantling shamanic interference during the 2002 World Cup engineered by the Mutant Gangrene.

Post-conflict, X-Car continues refining Spark Engine efficiency despite their deactivation after the Mutants’ defeat, with archival logs noting preserved aesthetic upgrades in his depleted state.

Toyline iterations feature translucent variants and limited-edition Super Mode designs with advanced aerial maneuverability, all retaining integration with Hot Wheels track systems to accentuate vehicular speed dynamics.
