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. He was killed by Galaxy Mega & Super Armor Shine Gingaioh.
- Captain Gregory was designed by character designer Akira Nozaki.
- The reason he was unadapted to Power Rangers Lost Galaxy, either movie footage costed extra or the In Space and Lost Galaxy team-up had a different motive.
