Hostile Program

The Hostile Program is an attack virus created by the MCP, and is found in Kingdom Hearts II. It is one of the bosses at Space Paranoids. It appears to be based on the local Heartless, though it is not a Heartless, and its basic body is a grey, robotic creature.

Kingdom Hearts II
Upon realizing the threat of Tron and Sora, the Master Control Program had Commander Sark deploy a special program virus called the Hostile Program. It caused chaos for the computer world as well as the real world in Hollow Bastion. After defeating the Hostile Program, Tron gives Sora the Photon Debugger keyblade.

Strategy
The Hostile Program is quite simple. Collect the clusters which drop until you have maxed out the gauge, then cast the "Freeze" Reaction command. The Hostile Program will then stop momentarily.

Switch into your Drive Form and begin unleashing your strongest attacks. A simple strategy would be to use your "Setup" Limit command, as the Hostile Program is quite weak against this attack.

Keep an eye on the large clusters that the Hostile Program towards you. It will either collide into you, or rapidly fire several lasers at you. These can easily be avoided, but may outnumber you. Once the Hostile Program has taken enough damage, it will begin to charge around the room several times, so quickly run to the center.

It's second attack is similar to a laser pointer, emitting from it's hands. This attack is slow, but you will need to avoid them. A second occasion is when the Hostile Program sends these beams swarming all over the place. It can be tricky to avoid, so watch the pattern carefully. Try dodging and jumping, although I can't guarantee you won't get hit at least once.

If they begin spinning around the room, you need to jump. If they begin to move in a vertical motion, wait until you are able to pass underneath them and get out of it's path. When they start spinning around the room quickly, you might see it as a nightmare to avoid it, but watch the pattern, as you will eventually get the hang of it.

Because this battle requires to collect orbs, equip Explosion. This easily increases the amount of orbs that drop.

Trivia

 * The Hostile Program, The Experiment, Hayner, Riku, and the Lingering Sentiment are the only five boss characters in the game who are not originally Disney or Final Fantasy characters, Heartless, or Nobodies, though the Hostile Program and The Experiment are based on Disney characters. These characters are located in the journal entries as antagonists, with red squares.


 * Hostile Program could not be defeated on early copies of PlayStation 3. Instead of firing lasers, it became invincible. This bug can now be fixed by downloading an update from PlayStation Network.
