List of the Sidians that appear as Intruders. Intruders are stronger than Irregulars and you might need a stronger team or the use of your Company to defeat them. If you lose the battle, it doesn't disapear like any other Irregular battles. It stays in your Feed until you defeat it. But unlike Exceptionals (where your friends can come and help you defeat them), Intruders can only be defeated by you, you're friends can't help.
