Drones

Vilgax's drones are drones created by Vilgax to serve him and get the Omnitrix. Drones are robotic rather than organic and are red. These drones can be merged with an organic matter as shown in The Alliance also Vilgax can control the merged signal. There are also gigantic robots which serve him as well. It is mentioned that Vilgax created robots because no one else dared to be around him.

Types of Drone

 * Basic Drone - These small, weak, UFO-shaped drones were the most commonly seen drones in the series. They were capable of flight and had several small limbs armed with lasers and blades. They can also fuse with organic creatures (e.g. Rojo). They first appear in And Then There Were 10).
 * Gigantic Robot Drone - Roughly 30ft tall with more humanoid features and 3 insectoid legs. They possess great strength and large claws, can spawn Basic Drones from their shoulders, can create laser blasts, and spin their legs to become a mini tornado. They first appeared in And Then There Were 10.
 * Bioid - Small humanoid drones that are barely used for combat, and usually seen on Vilgax's ship. They are capable of speech, unlike other drones, and possess laser guns, grenades, and jet packs (They first appear in And Then There Were 10)
 * Mechadroid - Slightly larger than the Basic Drone, and barely any different in appearance, though Mechadroids have recognizable faces and spider-like legs rather than the Basic Drone's limbs. They are able to merge with machines in order to gain more abilities, such as attaching a tank to itself to use its cannon, and for each machine merged with, they grow larger and stronger. First appeared in The Visitor.
 * Bioid Army - An army of hundreds upon thousands of tall, white, synthetic drones with no faces or weapons. They have blank DNA, and can be synced to the Omnitrix in order to transform all of them into any form selected(basically making an army out of one alien form), giving them any and all of that alien's powers. They communicate by chanting the name of the alien form they are currently in. First seen in the Alien Force series two-part finale,The Final Battle Part 1 and The Final Battle Part 2.
 * Flying Drones: They are Biods that can fly and change into a jet.
