|“||I bet this guy wouldn't be such a big shot without his sword!”|
|— Sword Soldier's Cast Description • Kirby's Epic Yarn|
Soldiers look identical to Mariners; the only difference between the two is their colors. Mariners have blue heads and eyes with light gray bodies, while soldiers have red heads and eyes with black bodies. There are four different types of soldier: Sword Soldier, Spear Soldier, Cannon Soldier, and Whistle Soldier.
Like Mariners, Soldiers are controlled by Yin-Yarn.
Soldiers will attack Kirby and Prince Fluff if they get close. Soldiers attack differently based on the weapons they hold. Sword Soldiers run toward their target, recklessly swinging their swords. Spear Soldiers rush toward their target, thrusting their spears at him. Cannon Soldiers will tilt their heads sideways and fire a spiky cannonball at their target. Whistle Soldiers don't attack at all, but instead blow their whistles, which summon other soldiers to the area. The Whistle Soldiers then pulls out two flags and dances, possibly trying to cheer on the others.
- Like with a Mariner, a Soldier will look confused if Kirby or Prince Fluff jumps on his head.
