Zip Slasher

The Zip Slasher (ロールスラッシャー) is an Emblem Heartless exclusive to Kingdom Hearts 358/2 Days. It appears as an incredibly powerful Heartless with great amounts of HP and high damaging potential in several missions. Throughout the game, the Zip Slasher appears as an enemy with incredible strength compared to Roxas's expected strength during the mission it appears in, usually at lease twenty levels higher and capable of completely draining Roxas's HP with one combo. The Zip Slasher is most likely expected to be defeated by the player when they revisit the mission once they are strong enough to hold their ground against the powerful Heartless. It first appeared before Roxas and Marluxia as an optional boss in Twilight Town.

Kingdom Hearts 358/2 Days
This sword-wielding Heartless's skillful defense makes it tough to finish off. ''Its spinning slash has the added effect of damage-draining HP from victims. Watch for it, then evade or deflect it with a block.''

Appearance
This Heartless is rather small, about as tall as Roxas. Its armor light blue in coloration, it is basically a smaller version of the Dual Blade Heartless. This would suggest that the Zip Slasher and its larger cousin are connected in some way.

Strategy
The Zip Slasher is indeed powerful. It imunne to all forms of magic, so physcial attacks with your weapon are your only way to damage the Zip Slasher. Also only use limit breaks when it is low on HP or on it's last HP bar, as it can still attack with its deadly combo. You can sometimes freeze it with upgraded blizzard spells but it doesn't stay frozen for long so be prepared. It does not hesitate to attack, immediately lunging at Roxas. This tactic is easily predicted, as the Heartless's blades glow green, and can be avoided with careful timing of the Guard or Dodge Roll abilities. The Zip Slasher's technique is to do a powerful spinning attack, then lunge toward Roxas with its powerful sword-like arms. It should also be noted that the best time to attack this Heartless is when it pauses after each attack, which is about enough time for two combos. Despite its great amounts of health (a grand total of 11 HP Bars), the Zip Slasher can be defeated easily when the player revisits the mission. Also, the Zip Slasher will heal whenever it lands its powerful combo, which can make this a tiresome battle. A well timed blizzard spell has the potential to freeze him, leaving a few seconds to deal huge damage. You can usually eliminate 2 or 3 bars if you have a decent weapon equipped. The best time to blizzard him is right before the second part of his attack, where he lunges both blades at you.
