Ogre

The Orcus (オーガ) is a Heartless Boss that appears in Kingdom Hearts 358/2 Days. It is very similar to the Invisible Heartless from Kingdom Hearts, but is red and larger. The Orcus is fought on Days 352 and 353.

''Though faster and more powerful, these Heartless are otherwise the same as the Invisible. They attack with a fearsome shockwave.'' ''Time your combo finisher so it connects right after they catch their sword. This will cancel the shockwave and leave them open.''

Trivia

 * The first time Roxas and Xion encounter an Orcus is on Day 352 in Halloween Town. It was revealed that the Orcus was actually Xion to Roxas and Roxas to Xion. This was a trap devised by the more superior Organization members to test who is the stronger member.
