Icon-bioman.png This article is about a/an mecha and its components in Choudenshi Bioman.

Bio Robo (バイオロボ Baio Robo): Coming from the Bio Star 500 years ago, it is the BioRobo that showers five youths with Bio Particles. It is the BioRobo that also gathers our five protagonists together, literally picking them up like action figures. It is also semi-sentient, showing fear at the arrival of Silva. It is formed from the two Bio Jets when the command "Fusion! Hyper Cross!" (合体!ハイパークロス! Gattai! Haipā Kurosu!) is given. It is armed with the Super-Maser (スーパーメーザー Sūpā Mēzā) sword and it destroys monsters with a variety of finishing attacks including, but not limited to, Concentration (コンセントレーション Konsentorēshon), Comet Cutter (コメットカッター Kometto Kattā), Chainsaw Cutter (チェーンソーカッター Chēnsō Kattā), Straight Flush (ストレートフラッシュ Sutorēto Furasshu), Pinball Sting (ピンボールスティング Pinbōru Sutingu), and Dashing Beam (ダッシングビーム Dasshingu Bīmu). It uses a powered up attack, the Bio Particle Cut (バイオ粒子斬り Baio Ryūshi Kiri) against later monsters. In the Philippine Dub, the fusion of the Bio Robo had renamed as Bio Integrate!. The Super-Maser sword becomes as Super Laser sword and four of it's techniques have renamed as Straight Thrust, Triple Slash, Destructo Slash, and Giant Top Spin but maintains Concentration and Bio Particle Cut. The toy version refers it as Electronic Fusion Bio Robo (電子合体 Denshi Gattai Baio Robo).

Later history

Gaoranger vs. Super Sentai

Bio Robo, as one of the past Sentai Giant Robos, imbued Hyakujuu Gattai GaoKing with its power to defeat the giant Lost Highness Rakushaasa. Tvicon.png TV STORY-Hyakujuu Sentai Gaoranger vs. Super Sentai


When GokaiOh and Gosei Great faced the Black Cross Colossus, the mecha of the first 33 Super Sentai, including Bio Robo which possibly manifested from a toy version like DaiDenzin and the Variblune, appeared to back them up. When the Black Cross Colossus summoned several giant villains to oppose them, Bio Robo fought alongside GekiTohja and Great Five to destroy Buredoran of the Comet. 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. Tvicon.png TV STORY-Gokaiger Goseiger Super Sentai 199 Hero Great Battle

Zyuohger vs. Ninninger

Zyuoh Ninnin Super Sentai Burst.

Representing Bioman, Bio Robo appeared among manifestations of the first 38 Super Sentai's mecha that granted Wild Tousai Shuriken King the power to perform the Zyuoh Ninnin Super Sentai Burst which destroyed the titanic Gillmarda.

Behind the scenes


Bio Robo is featured as #85 in the 1986 archive compilation video Toei 100 Great Heroes Super FightIcon-crosswiki.png.


Bio Robo as depicted in the post-break Bioman eyecatch.

  • Bio Robo is unique in being the only time where the Red does not pilot his own mecha alone but without his entire team, due to Bio Jet 1 being shared with Pink5. In all other mecha the Reds control with multiple members, it is a combined cockpit (such as with Battle Fever Robo, DaiDenzin or Galaxy Mega)
  • Bio Robo is the first sentient mecha in Super Sentai.
  • In episode 10, Bio Robo's Eyes glowed to trigger the deceased Yellow Four1's Bio Hologram to show a footage of Mika which is her shot in the Closing Sequence.
  • Bio Robo has the most sword finishers out of any primary Sentai Robo.
  • The suit's legs would be repurposed as Grand NascaIcon-crosswiki.png's legs in Jikuu Senshi SpielbanIcon-crosswiki.png
