As a small Heartless with little HP, the Deserter has white claws that it only uses when pressed in a tight situation. It is similar to the Stealth Soldier, yet is less offensive and lacks invisibility powers.
The Deserter bears the Heartless emblem on its chest, dangerous yellow eyes gleaming underneath its silver helmet.
Its name, "Deserter", is a military term given to those who run away from the military, an appropriate name for this Heartless as it runs away from the fight unless pressed into battle.
While Deserters are not particularly offensive, they are quite the annoyance. Appearing in large groups, they run around the battlefield at high speeds, making attacks hard to land. Once you corner one, brace for a small attack, and hammer it with the Keyblade until its short HP bar is depleted.
Furthermore, when you defeat one Deserter, its companions will swarm you and will attack all at once. However, blocking their attack gives you the advantage, as it knocks them off their feet. Use that opportunity to deplete them.
Blizzaga is also helpful, since it has a wide range. It is best to use a weapon that works well in midair as it can trap them in a combo without them escaping.
