Fiverobo is formed from Sky Alpha, piloted by Five Red; Carrier Beta, piloted by Five Black and Five Yellow; Land Gamma, piloted by Five Blue and Five Pink; and the Five Trailer support unit.

Together, these machines combine into the team's primary giant robot.

Fiverobo is the primary giant robot of the Fivemen. Its arsenal includes the Super Dimension Sword, Twin Cannons, and the Sure Kill Kick.

The Super Dimension Sword can be used for both single-sword and double-sword finishing attacks.

Star Carrier is a powerful support machine built by Dr. Hoshikawa and brought to Earth by the mysterious alien warrior Gunther.

It transforms into Starfive, giving the team a second major robot form.

Starfive is the robot mode of the Star Carrier. Its weapons include the Star Gun and the Star Hang Beam.

Super Fiverobo is formed when Fiverobo combines with Starfive. This upgraded formation significantly increases the team's power and utilizes attacks such as the Jet Knuckles and the Super Vector Punch.

Max Magma is the massive final formation created when the Magmabase combines with Super Fiverobo. Its strongest attack is the Diamond Max, which fires all of the weapons mounted across its body simultaneously.
