Soldier

Soldiers are enemies from all Kingdom Hearts games.

Kingdom Hearts
"Heartless that emerge from various places. They are brisk in their movements, and rush into their opponents. However, they are not that tenacious. They often appear in numbers, though they lack teamwork."

Kingdom Hearts: Chain of Memories
"A swift-moving Heartless that attacks its prey with a spin kick. Its whimsical nature makes the Soldier a less than tenacious foe."

Kingdom Hearts II
"It unleashes decent attacks from every angle. Stay alert when fighting it! It counterattacks with a kick, so retaliate with Cyclone to float in midair and unleash combo attacks!"
