Decoy Queen

The 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 chip and secretly starts studying other alien chips found by The Plumbers. However he is caught removing them from the Vault & is accused of stealing them by Max. Validus tries to warn Max about the Nanomechians/The Hive, but Max doesn't believe him & 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 & 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(thats what Ben said). She puts 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.

Powers
The Queen is, like all of her kind, capable of controling humans but being the Queen she's much more powerful than the Hive's normal drones and is capable of reproducing drones at a rapid speed. She can also sprout wires she can use to fire powerful electrical blasts. She's also capable on controling the normal drones telepathically and like other members of the Hive can adapt if needed.

Weakness
The Queen is extremely small, though larger than the normal drones, making her easily crushed by human sized beings. She is also incapable of controling half drones like Nanomech. Also, if the Queen is destroyed, the Hive will die as a result.
