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.

Kingdom Hearts 358/2 Days
''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/Xion encounter an Orcus in Day 352 in Halloween Town, it was really Xion/Roxas with his/her appearance changed, because it was a trap devised by the superior Organization members for one of them to eliminate the other.
