Hostile Program

The Hostile Program is a boss from Kingdom Hearts II. Upon realizing the threat of Tron and Sora, the MCP 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. It somewhat combined the attributes of the Strafer, the Magnum Loader, and the Devastator, though it itself is not a Heartless. The Hostile Program was the first boss of Space Paranoids. When the Hostile Program is hit a certain number of times, the outer shell will fall off. It battles largely using lasers. It has three eyes, each similar to the ones Heartless have.

During battle, the Hostile Program moves only in a circle around the room and fires many lasers at the party. 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 palce. It can be tricky to avoid, so watch the pattern carefully. Try dodging and jumping, although I can't guarentee 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, along with the Experiment in Halloween Town, Hayner, and Riku, are the only four boss characters in the game who are not Disney or Final Fantasy characters or connected to the Heartless or Nobodies in some way. 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.
 * As you fight it, pieces of its armor and body are destroyed, and the final part is its gray central body and claw.
 * The apprearance of Hostile Program may be formed from data stored of the Heartless that only the MCP may have had access to.
