Dual Blade

The Dual Blade is an Emblem Heartless that is found in Kingdom Hearts 358/2 Days. It is one of the bosses in Halloween Town.

Design
A Dual Blade is a large, humanoid Heartless covered from head to toe in silver and grey armor. The armor on its legs sport white spikes and steel blue highlights. Its helmet sports two short, white spikes and a long, twisted, black antenna. A small opening in the front just barely exposes the Dual Blade's black face and glowing yellow eyes. Its most notable features are the blue interweaving blades in place of each of its hands. It has two Heartless emblems, one on each of its shoulder pauldrons.

The Dual Blade's name is a clear reference to the two blades on its arms that it uses to attack.

Strategy
When facing a Dual Blade, it is best the player keep in constant motion to avoid the Heartless's attacks. Block its spinning thrust attack, and jump to avoid the Aerora spells it launches. When the Heartless jumps high into the air, be sure to jump and Glide out of the way, or suffer damage when it comes down and causes a short-ranged shockwave to erupt. A well-timed Dodge Roll can also prevent damage. When the Dual Blade charges power, immediately Block to avoid the powerful long-range slash attack that follows, as it may inflict the Air-Toss status effect. Blocking this attack successfully will cause the Heartless to collapse, increasing damage that can be done with magic or attacks. As the Dual Blade's journal entry suggests, Thundaga will have the same effect on this Heartless. Once it recovers, the Dual Blade will use the attacks in its arsenal at random. So long as one heals regularly and uses their Limit Break or magic as needed, the Dual Blade should not be much of a challenge.

On Mission 54, the pumpkin bombs on the floor is pretty useful. After hitting one of them, lure the Dual Blade to get near it, and the explosion should take out 1 bar of the Heartless's HP.
