History
Battle Fever Robo was prepared by the National Defense Ministry as Team Battle Fever's secret weapon against the Secret Society Egos. It was still under construction as Team Battle Fever was assembled and fought their first battle against Egos' Umbrella Monster. After the defeat of the Fang Lion Monster, Satan Egos, aware that a secret weapon was being developed but not knowing what it was, sent Commander Hedder and his Cutmen to acquire information on it by force but was foiled by Battle Fever. Following this, General Kurama Tetsuzan had Masao Den "steal" fake blueprints for the weapon, delivering them to an undercover Egos Monster while exposing a mole who revealed before being slain by the monster that Egos was developing their own giant robot.

In another attempt to uncover the secret weapon, Egos captured the researcher Segawa. Finding that their devices were not able to unlock the information from Segawa's mind, Satan Egos recruited the psychic Bengal Tiger to read his mind only to find nothing, proceeding to execute Segawa as he was of no use. Bengal Tiger would find, however, a connection in Keiko Nakahara. Sensing that she was a member of Battle Fever who held knowledge of the secret weapon, Bengal Tiger kidnapped her in order to gain the information but was defeated by Team Battle Fever whom rescued Nakahara.

Ultimately, Egos kidnapped the children of the Information Supervisor Sakaguchi, blackmailing him into stealing the Battle Fever Robo's blueprints. By this point, however, the Battle Fever Robo had already been finished though Sakaguchi told Hedder that it was being rushed to completion. Egos likewise had completed their first 'Little Brother', the giant Buffalo Robot, and, though Sakaguchi gave his life to destroy the secret factory in which it was constructed, it was nevertheless launched and sent to attack. After defeating the Buffalo Monster, Team Battle Fever were summoned back to their Big Baser where they boarded the Battle Shark to face Egos' robot. Finally, finding themselves under attack from the Buffalo Robot after destroying a squad of Egos Fighters, Team Battle Fever, having been instructed in controlling the machine by Tetsuzan, boarded the Battle Fever Robo which was launched from Battle Shark. Engaging the Buffalo Robot, Battle Fever Robo prevailed in its first battle by utilizing a selection of several weapons, destroying the Buffalo Robot with the Cross Fever.

Faced with the obstacle of Battle Shark and Battle Fever Robo, Satan Egos devised a plan to lure and eliminate them. Having the Doguu Monster dropped off in the guise of a statue by the Okomisaki Radar Base, this Trojan Horse allowed them to capture the radar base. Using the base's facilities to give false headings to the Battle Shark which had arrived in response to the appearance of the Doguu Robot, sending it into an ambush in which the Battle Shark's hull was breached, forcing it to return to base. However, having discovered a secret entrance to the radar base via a cave thanks to a junior explorer, Team Battle Fever was able to reclaim the base. After the Doguu Monster was defeated by Battle Fever, the Battle Fever Robo was launched to engage the Doguu Robot, which it destroyed with the Cross Fever after employing further weapons in battle.

Battle Fever Robo used the Battle Shield for the first time against the flame of the Fireball Robot before enduring its finger missiles, proceeding to destroy it with the Cross Fever.

Engaging the Sports Robot, Battle Fever Robo wielded the Attack Lancer to counter the opponent's hockey stick followed by using the Chain Crushers to trip it up before destroying the Robot with the Cross Fever.

Meeting Icicle Robot's ice spear with the Lightning Sword, Battle Fever Robo endured the Robot's cold before using the Attack Lancer with the Chain Crusher followed by the Fever Axe to provide an opening to destroy it with the Cross Fever.

In its fight with the Naumann Robot, Battle Fever Robo was quickly disarmed of its Lightning Sword, using the Battle Shield to protect from the assault before throwing the Fever Axe to disable the Robot which allowed Battle Fever to destroy it with the Cross Fever.

Wielding the Attack Lancer against the Cobra Robot, Battle Fever Robo fought off its attempt to constrict it before destroying it with the Cross Fever.

Facing the Robot Roselinka, Battle Fever Robo met her rapier with the Attack Lancer, using the Battle Shield to defend against a flame which she spewed from her blade before using the Chain Crusher to disarm her, allowing Battle Fever to destroy her with the Cross Fever.

Sun Vulcan
Battle Fever Robo appeared as blueprints for an experimental weapon that the Guardians of World Peace were working on to assist Sun Vulcan's own robo in battle against Black Magma, complete with the BF symbol on the chest. Ultimately, however, the weapon was evidently not completed in time as Sun Vulcan was able to destroy Black Magma without summoning it.

Gokaiger
When GokaiOh and Gosei Great faced the Black Cross Colossus, the mecha of the first 33 Super Sentai, including Battle Fever Robo which possibly manifested from a toy version like DaiDenzin and the Variblune, appeared to back them up. Variblune and Sky Ace proceeded to assault the Black Cross Colossus, followed by Battle Fever Robo using its Chinese Bamboo Slice on him. When the Black Cross Colossus summoned several giant villains to oppose them, Battle Fever Robo fought alongside Dyna Robo, Flash King, and DaiBouken to destroy Hades God Ifrit. After all the giant villains were destroyed, all 35 mecha weakened Black Cross Colossus with a combined attack before GokaiOh combined with the Variblune to become Goren GokaiOh which destroyed the Black Cross Colossus with the Gokai Hurricane: Cassiopeia finisher. With the battle won, the 33 past Super Sentai mecha vanished.
