Kingdom Hearts 358/2 Days
This icy knight Heartless's skillful defense makes it tough to finish off.

Though its focused slash can be stopped with a block, blasting the knight with Firaga while it is storing up energy will 

stagger it, opening it up to extra damage, especially from magic.

Appearance
The Chill Ripper is in the same family of Heartless as the Zip Slasher and Dualblade, larger, its twin blades are incased in thick layers of ice. This Heartless' armor is a dull gray in coloration.

Strategy
The battle with the Chill Ripper is no easy feat. While you don't have to take care of Xigbar, who will heal and perform attacks himself, it is important to watch Roxas' HP, or the player may very well end up dying. In battle, this Heartless utilizes two attacks. One is a lunging spin attack which deals heavy ice damage, the other, similar to a sleight utilized by Vexen in Kingdom Hearts: Chain of Memories and Re:Chain of Memories, causes pillars of ice to erupt from the ground. Both of these attacks are easily avoidable, should you choose to keep your distance. While you should attack whenever possible, the Chill Ripper is agile, and will jump around the field to avoid you.

It is important that the player heal regularly, and utilize the Limit Break, should their HP hit the "alarm zone." If this strategy is followed, then they should have no trouble dealing with this boss. It should be noted that should the player utilize the Guard Ability and successfully parry the Chill Ripper's attacks, it will fall to the ground for a short time, dazed, allowing you to deplete a good portion of its great amounts of HP before standing again.

Trivia

 * The battle theme in the Chill Ripper battle is a currently unnamed song from 358/2 Days, an apparent mixture of "Struggle Away" and "The Fight for my Friends" from Kingdom Hearts: Chain of Memories.
 * When fighting Chill Ripper in Mission Mode as King Mickey, there is a slight chance of going into an underground glitch. the glitch is treated like open air and it is possible to glide and air dash. After a while you will hit the bottom and your HP depletes immediately.
