|This article is about a/an villain in Seijuu Sentai Gingaman and Denji Sentai Megaranger.|
Captain Gregory (グレゴリ艦長, Guregori-kanchō, Gingaman vs. Megaranger) is an old friend of Captain Zahab's who came to Earth to revive the Space Pirates Balban, with the aid of Hizumina, Dr. Hinelar's second "daughter". He controlled a second Daitanix, who later became his personal Majuu, as Demon Beast Fortress Ghelmadix. He could make himself grow without the aid of an enchanted liquid. Eventually revived almost every Balban member along with almost every Majin. Was sealed long before Captain Zahab, by the Star Beasts, believed to be as strong, on his own, as the entire team of Space Pirates Balban combined. Amazingly, he was able to grow at will without consuming Baruba-X but was killed by & Super Armor Shine GingaiOh's Great Beast King Slash.
- Captain Gregory was designed by character designer Akira Nozaki.
- The reason he was not adapted into Power Rangers Lost Galaxy was because Power Rangers wished to use the Psycho Rangers (counterparts to the Nezirangers) in order to kill Kendrix and usher in Karone as Galaxy Pink.
