The leader of the Combatrons, Dolrailer transforms into a combat trailer. Cool and composed, he is a cruel and unfair evil general. He uses his four subordinates as if they were his own limbs, and hid demolition engineering can destroy anything on land. Dolrailer can also transform into a combat station and perform maintenance on his team mates. His large gun, the Dual-Laser Rifle, is a weapon no one but he knows how to handle, while the twin Dualbusters on his back can instantly turn everything in a 1km radius into a scorched wasteland. He isn't satisfied until he gets the bath first. Dolrailer can combine with the other four Combatrons to form Baldigus.
