RS Hopper

RS Hopper are four drone-like support weapons that appears in the Rebuild of Evangelion movie series.

Profile
RS Hopper are used by Evangelion 13 for protection. Because Evangelion 13 doesn't generate it own A.T. Field, NERV created these support units in order to further defend itself. When not activated, those are stored in two compartments that are attached into the shoulder pylons that are expurged when activated. These support units are capable of generating an A.T. Field, defensive or offensive, and appear to act autonomously in order to defend Evangelion 13. Their movements seem automatized but also respond to the actions of the pilot or his emotions. They also have a special defense system that makes them self-destruct in an explosion, when they are eliminated.

All four of the RS Hopper have the same appearance: that of a vaguely elliptical object. Their bodies are composed of an unidentified semi-translucent material forming tendrils leaving a blue trail when they move in the air. These tendrils swell and contract to allow the RS Hopper to move, much like a jellyfish. In the center of each drone, there is a circular metallic object.

Evangelion: 3.0 You Can (Not) Redo
After Evangelion 13 is activated, NERV sends it to Terminal Dogma to retrieve the Spears that were located in the bodies of the Second Angel Lilith and Evangelion Mark.06. Shinji Ikari and Kaworu Nagisa are the pilots of Evangelion 13. As the two boys arrive in front of their objective, Evangelion Unit-02'γ, piloted by Asuka Shikinami Langley, attacks by surprise. Fortunately, the RS Hopper deploys from 13's shoulder pylons and generates an A.T. Field to protect it.

For several minutes, Unit-02γ attempts to hit 13 with melee without success. Each hit landed by Asuka is blocked by an A.T. Field from a Hopper. Finally, she manages to pierce the four drones which results in an explosion.
