The Phoenix Armor was listed as one of the four elements of the Hyribead by Amber Man. Save Amber Man, Blazer Cannon! There were rumours that it was buried by the Dragon Waterfall; as a result Heli Transer, posing as a traitor, was able to trick Diondra into doing much of the searching for the shield. His plan was complicated when suspicions of treachery fell on him - though the actual source of the leak was Grujios, who had made a clone body of Battle Gyror. A confrontation near the Waterfall saw the Shield found by Baikanfu and Double Jet during a battle with the Gyandlar captain Asura, but it was captured by Diondra and successfully delivered to Gadess. Raise Your Gun, Heli Transer! After Gadess stole the Phoenix Armor, Dragon Helmet and Wolf Sword from the Machine Robo, Gadess had complete access to the Hyribead. Mighty Fortress, Heavenly Sword - Jet Don't Die! However, Rom was able to vanquish Gadess by combining his Wolf Sword with the Star Sword of his brother Guardi, taking back the four Hyribead elements - which he then used to restore Cronos.
