The R-SUEZ 104X is the helicopter on Super Villain Island. It is owned by the oil company manager. You have to parachute out of it when the pilot can't land due to weather conditions, and it picks you up at the end of the Island.
The letters "SUEZ" is "ZEUS" spelled backwards, which foreshadows Zeus's role as the main antagonist in the island.
The pilot (name is unknown) is probably affliated with the team of oil rig workers you meet when you first drop on Super Villain Island.
