Varia

Varia is the weapon of Umber Russett. It is otherwise known as the Kinetic Flow Attack Drone and acts as a long-range assault rifle robot.

Description
Varia is an orb-shaped droid about the size of Umber's head. It also has three-pointed wings on its side that help the streamlined shape, along with having four protruding spikes on the sides, bottom, and back. The front of the drone has a transparent screen that displays Umber's emblem. This screen, along with the four spikes and the middle section of the wings, glow turquoise/green as an effect of using Wind Dust as fuel. Using this particular type of dust allows it to use air displacement to hover in place. The drone is also equipped with two semi-automatic guns that shoot converted Dust energy as bullets. In terms of energy use, it uses 50% for this weaponry (40% as ammo, 10% for mechanics) and 50% for fuel or other processes.

Despite being a disconnected weapon, Umber still has complete control over it through the use of the motion controller in her glove. These are activated with her semblance, that converts kinetic energy from movements (in this case, gestures) into potential energy to channel into a target. In this case, she channels it into electrical energy to send to the transmitters in her glove, which then relay the gesture to Varia near-instantly. The following is a list of hand signals and their reactions.
 * Hand spreads out and sweeps to a side -- Activates Varia from Idle Mode or Deactivation. Umber commonly throws Varia upward before doing this, but makes sure she is ready to catch it in case it doesn't work.
 * Hand swings in one direction -- Varia will dodge/move to the corresponding direction, depending on the speed of the swing. A slower swing is a slower movement.
 * Hand spread open and thrust forward -- Varia will shoot ahead of itself for 1 second. If she keeps the position up for longer than this time, it will shoot for as long as she maintains the pose. When stopped, Varia returns to following Umber.
 * Clenches fist and bends arm at elbow -- Varia will enter Idle Mode and return to Umber's side. It remains floating and tracks the movement of the glove to find Umber's location to follow. Actions other than that of 'Reactivate' will be ignored.
 * Clenches fist, bends at elbow, then opens hand -- Only works from Idle Mode, but Varia will deactivate. The open hand is done so it will place down into her hand and avoid dropping it.
 * Places a fist over heart, then quickly swipes to her left hip -- activates Sabotage Mode. This is a trap mode created in case Varia is ever stolen and she is required to tell how it works. When activated, Varia will track the glove and shoot at the sensors on the lower hand.

Trivia

 * The drone was named Varia as Umber considers the whole machine as one big variable after all the mistakes she made making it.
 * When testing Activation Mode, there was more than one occasion when she forgot to catch Varia when it didn't work. This lead to a lot of time spent repairing it. Similar things happened when she failed balancing it when Deactivating it.
