The Gun Hunter is a character that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. It is a line of robots produced by the Guardian Units of the Nation in their ongoing conflict against Dr. Eggman and the Eggman Empire.
G.U.N. employed these robots in several locations during their efforts against both Dr. Eggman, Sonic the Hedgehog and his allies prior to the averted cataclysm involving Space Colony ARK. Several Gun Hunters were later stationed aboard a G.U.N. aircraft carrier that moved in off the coast of Avalon to assault the Eurish Egg Army, but proved unable to contend with the unexpected arrival of Dr. Eggman.
