Power and abilities
The Giga Trooper has the same abilities as that of GUN Trooper, except it has stronger armor, as it takes six hits from the Homing Attack and one shot from the Shadow Rifle to destroy. They usually hold the RPG to attack their enemies and they charge at an enemy when spotting it. They are the second most powerful GUN Robots in the game, only behind the Big Foot Type B.
In other media
In the Sonic the Hedgehog comic series and its spin-offs, the Giga Trooper is a mech used by the Guardian Units of the Nations. One was used during the organization's mission to destroy the New Black Comet.
