Invader Queen

The Venusian Queen is the leader of the Venusians and the primary antagonist of Metal Slug 6.

Story Behind The Venusians
When the second boss in Metal Slug 6 is defeated, Morden and the Mars People can be seen hiding so they can attack the players' characters. Right after they trap them, the flying Venusians come in and feast on the Mars People, and one attacks Morden. Then, Morden tells the players about trying to retrieve Rootmars at their base; Rootmars levels down and the Venusians attack the base, demolishing it. After this, Morden just fades out.

Later on, in the game's final mission, the Rebel Infantry will help the players get to the place where the Venusian Queen is being held. In the first part of this boss fight, the Rebels come to help again. When the first part is destroyed, the platform where the battle is taking place snaps, and all the Rebels that were there at the time (shielded Rebels) are killed, leaving the players' characters in a one-on-one battle with the Queen.

The War is Over
The Venusian Queen falls and implodes, making a huge, massive light. It blinds the players' characters, making them fall to their doom, only to be miraculously saved by either Morden or Rootmars. Then, the mission is all over. Together with the Rebel Infantry, they have defeated the Venusians and their queen.
