Peebo (ピーボ Pībo): An android who is the guardian of the Bio Particles, Bio Robo and Bio Dragon, built as an experimental robot when the Bio Particles were in development. He came to Earth 500 years ago and showered five courageous people with Bio Particles. Now that Gear has made its move, Peebo and Bio Robo gather the descendants of the original five. He shows a great fear for Silva. He cried at the death of Mika Koizumi. In the last two episodes, he used himself to energize Bio Robo.
Behind the scenes
Peebo is the source of what would become Alpha 5 in Mighty Morphin Power Rangers to Power Rangers Turbo. In Haim Saban's original pitch to adapt Choudenshi Bioman as Bio-Man, Peebo's costume was to be used for an equivalent character named "Alpha-5". Ultimately, however, the first Power Rangers series would be adapted from Kyoryu Sentai Zyuranger; while the robotic assistant character was retained, an original design would be created for Alpha 5—a design that featured red, blue and black as the primary colors for his body, his golden feet now much larger, and a head in the shape of the classic "flying saucer" with a flashing red bar for his eyes.
- Peebo's voice is that of a woman in the Philippines as English dubbing; the dub also changes his gender to female.
- Peebo's appearance and mannerisms are similar to that of C-3PO, the humanoid droid of the Star Wars franchise.
