The Scourge Splitters appear after you've retrieved the Time Crystal on almost every level in TimeSplitters 2, sporting guns from the Time Period that you are currently fighting in. These Splitters are believed to be the leaders of all the TimeSplitters. They are the most human-looking ones and stand on two legs. Their chest cavity is open and blue flames spew out. Their head is a floating featureless face with white eyes. If when playing as Scourge Splitter you pick up the Invisibility Powerup, the blue flames are still visible.
