Go-Buster Beet is BC-04 Beetle's Megazord mode. It is armed with the twin Beet Cannons, which can also become the dual-wielded Beet Swords. Its cannon-based finisher is the Beet Cannon Burst, while its sword-based finisher is the Beet Two Sword Cross. Go-Buster Beet's right arm can extend to unleash long ranged punching attacks or convert into a launcher for the SJ-05 Stag Beetle to dock in order to perform the Beet Catapult Attack finisher, which launches the SJ-05 through at its target. Go-Buster Beet can also use Go-Buster Lioh to attach onto his right hand to boost Go-Buster Lioh's attacks, such as the Lion Catapult Attack finisher. After Tategami Lioh appears, Go-Buster Beet also gets an update, where Go-Buster Beet can ride Tategami Lioh in Buddy Vehicle mode.
