Denshi Gattai Bio Robo (電子合体 バイオロボ,Denshi Gattai Baio Robo): Coming from the Bio Star 500 years ago, it is the Bio Robo that showers five youths with Bio Particles.
It is the Bio Robo 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 BioJets 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-English dub, The Super-Maser sword becomes a Super Laser sword and four of its 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 バイオロボ,Denshi Gattai Baio Robo).

TV STORY-Ep. 3: Our Friend, Bio Robo
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 GekiTouja 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. MOVIE STORY-Gokaiger Goseiger Super Sentai 199 Hero Great Battle
