When Ohranger Robo is damaged by an evolving Machine Beast, Gorou learns of an earlier U.A.O.H. mecha that could even the odds. However, the robot is consider too dangerous as it previously killed its former pilot.
Tropes:
- Big Damn Heroes: As Gorou is about to die, Shunpei's ghost appears in a vision to tell him how to properly control the robot.
- Bittersweet Ending: Earth is safe, but Ohranger Robo is crippled and needs to be repaired before returning to field.
- Finishing Move: Red Puncher's is a series of energy blasts from wrist-mounted barrels.
- Godzilla Threshold: Red Puncher is uncontrollable, but the crippling of Ohranger Robo requires need for it.
- How Do I Shot Web?: Gorou struggles with Red Puncher. His state of mind is key to controlling it to protect humans before Shunpei's ghost tells him that he must protect all forms of life so Red Puncher would comply.
- I Surrender, Suckers / O.O.C. Is Serious Business / Wounded Gazelle Gambit: Bacchusfund pleads with the Ohrangers not to destroy his Machine Beast while waving a white flag that they surrender. But it turns out to be a distraction for Bara Build to launch a sneak attack that cripples their robot.
- Near-Villain Victory: Ohranger Robo is badly damaged and Gorou barely masters piloting Red Puncher in time.
- No-Holds-Barred Beatdown: Once Gorou masters piloting Red Puncher, he punches the hell out of Bara Build before finishing him. It's an especially satisfying bit of payback for what he did to Ohranger Robo.
- The Reveal: Red Puncher was created before Ohranger Robo, but was deemed too dangerous to control.
