Since Security is the final boss in Normal Mode (second to last in Hard Mode), his attacks are high enough in power to kill an entire group of characters in a matter of minutes, or do lots of damage on Normal. His main attack is the Alarm, although it can use the 'Basic Attack' that most enemies use in battles.
Can be blocked by Neon Wall, the chip 'Auto Shield' or Neon Wall 2. Sends out five flashing balls that deals 9999 damage to independent party members.
