All three Steel Starbeasts were then sold to the Balban in an attempt to destroy the Starbeasts of the Gingamen. When the Gingamen were able to reach the hearts that still lived inside them on the night of the Star Festival, the Steel Starbeasts broke free and joined the Gingamen as allies.
GigaRhinos is armed with the double barreled Gigantis Buster cannon which can fire either single blasts or a rapid fire barrage. In battle, it possesses great strength which it uses to ram through opponents along with great mental focus, which enabled it to resist the illusory powers of the Iliess Majin Merudameruda. When deployed alongside GigaPhoenix, the two are able to combine for an energy cyclone attack. It and GigaPhoenix were both destroyed after fighting Demon Beast Daitanix II in Gingaman vs. Megaranger.
GigaWheels
When not battling, GigaRhinos exists as the five GigaWheels that are stored in the rear bay of GigaBitus. When needed, the GigaWheels are deployed from GigaBitus' Scramble Mode and combine into GigaRhinos through "Beast-Land Fusion". They and the GigaWings are both controlled by the spirits of their respective Starbeasts and don't require pilots to function.
