Galaxy Soldiers (銀河戦士, Ginga senshi in Japan) are characters in Kirby: Right Back at Ya!. They are members of the Galaxy Soldier Army, which fought against Nightmare and his monster army in the great war. Anyone who takes up arms and joins the Army are considered a Galaxy Soldier. Star Warriors (星の戦士) fought alongside Galaxy Soldiers, but remain a largely separate association. Sir Arthur is a Galaxy Soldier and leader of the Galaxy Soldier Army, and is one of the few survivors of the war.
The English dub of the anime does not refer to the Galaxy Soldier Army or the Galaxy Soldiers at all, but rather refers to all members of the resistance against Nightmare as Star Warriors. In the actual Japanese version, very few characters are ever called Star Warriors - only Kirby, Meta Knight, and Knuckle Joe's father.
