Decoy Queen

The Decoy Queen is the main villain in the live action movie Ben 10: Alien Swarm. She takes the body of former Plumber Victor Validus as her host body. Validus discovers he had been infected by the alien chips and secretly starts studying other alien chips found by The Plumbers. However he is caught removing them from the Vault and is accused of stealing them by Max. Validus tries to warn Max about the Nanochips/The Hive, but Max doesn't believe him and expels Validus from The Plumbers.

Validus keeps on studying the nanochips (which are actually members of the Hive), until he is completely taken over by the Queen. The Queen uses the Hive Chips to infect human hosts and plans to take over the entire planet.

However her plan is thwarted by Elena, Gwen, Kevin, and Ben (in the form of his new alien hero, Nanomech). Even though she tries to control Ben as Nanomech, she is unable to do so as Nanomech is still half-human (because the chips can adapt and humans never give up, at least according to Ben, since that's what Ben said just before he killed her). She put up a brutal fight but in the end, the Queen is killed by Nanomech's bio-electric blast. With their Queen destroyed, the Hive quickly dies, freeing their victims and ending their threat.

In Ben 10 Ultimate Alien episode Revenge of the Swarm, it was revealed sixteen-year-old Elena Valadis is the real queen of the Hive all along( the Queen in Alien Swarm was just a decoy produced so that Ben wouldn't suspect her) in which she tried to keep Ben away from Julie in order to keep Ben all to herself. Ultimately, when she made Ben to go into mouth of death,she was convinced by Julie to stop all this if she really loved Ben, and that moment Elena took control and sacrificed herself. Though she still might be alive sense the Nanobots are still opperational.

Powers/Abilities/Capabilities
The Decoy Queen is, like all of her kind, capable of controlling and manipulating humans but being the Queen(Decoy) she is much, much stronger and much more powerful than the Hive's normal drones and is capable of reproducing mass numerous drones at a rapid speed. She can also sprout wires that she can use to fire extremely strong and powerful electric energy blasts. She is also capable of manipulating and controlling the normal drones telepathically and like other members of the Hive can easily adapt if needed.

Weaknesses
The Decoy Queen is extremely small, though larger than the normal drones, making her easily crushed by human sized beings. She is incapable of controlling half drones like Nanomech, but she can partially influence them. Also, if the Queen is destroyed, the Hive will die as a result, however this was not the real queen and just a decoy, thus it would meen that Elena would have to die.

Trivia

 * The Decoy Queen is the smallest villain Ben has fought.
 * The Decoy Queen originally was thought to control The Hive, when she dies The Hive dies. However with Elena being the true queen all along the decoy is just a drone.
