|This article is about a/an villain in Kidou Keiji Jiban.|
Doctor Giba (ドクター・ギバ Dokutā Giba) is the brown-haired, bearded human-looking leader and founder of Bioron. His real identity is Gibanoid (ギバノイド Gibanoido), a bio-monster born by accident from the chemical waste of Doctor Igarashi's National Science Academy Bio Laboratory. As a result, Giba is filled with malice for humans. He assumed his true form in the series finale, using Mayumi as a shield to escape in his ship. He died while fighting Jiban on his ship as it crashed into the mountainside.
In the Philippine Version of the series, he is renamed as Professor Stevie.
