On the Onslaught map, "Tricky," you'll notice that the stadium's grandstands are completely empty...not quite. Get any wheeled vehicle and drive up the massive tower at the north of the map. Using a sniper rifle, search the stands behind the tower and you'll find one dedicated fan. He's the same character whose in the Unreal Tournament 2003 opening video and gets assaulting by Gorge when he jumps the fence. He also appears in another egg at the bottom of the Gael pit behind a panel of bloody glass.
