The Shield Hunter (シールドハンター,Shīrudo Hantā?) is an enemy that appears in Sonic Adventure 2 and Sonic Adventure 2: Battle. It is a mass-produced robot model deployed by the military organization Guardian Units of Nations, and a part of the Hunter series. Unlike other models in its series, the Shield Hunters put emphasis on both defense and offense.
Nearly identical to the Laser Hunters, the Shield Hunters are blue, white, yellow, red and black humanoid robots with a top-heavy upper torso. They have a flat head with no neck, a single red eye, and a drop-shaped blue cap covering it. On their torso they have red and blue chest plating with the number "02" on the left side and GUN's symbol on the right. They also have thin legs with large kneecaps, thick forearms, a hand on the left arm, and a rifle identical to the Laser Hunters' on their right arm. What distinguish them are the tall red shields emblazoned with the number "02" they each wield.
Certain Shield Hunters have different designs depending on the Stage. Those in Crazy Gadget have red shields and the number "01" emblazoned on both their chest and shield (in the GameCube version, the number "02" is emblazoned on both their chest and shield instead), and those in Security Hall have black shields with the number "02" emblazoned on both their chest and shield.
In the Dreamcast version, the protruding part of their shields is wide and the steel frames around the edges are narrow. In the GameCube version and later re-releases, the shields are are made more rectangular and their steel frames are clearer.
By comparison, the Shield Hunters are not as frequently encountered as the Gun Hunters. They can be found in the following Stages:
Unlike other Hunters series units, the Shield Hunters never drop down from above or appear in standby mode. Insteade, they remain in one spot from where they take aim at the player. When destroyed, each Shield Hunter awards the player with two hundred points.
In gameplay, the Shield Hunters' shields can deflect any frontal attack without taking damage. Like the Laser Hunters, when engaging the player, the Shield Hunters lock onto the playable character when they are within range and charge their rifle briefly before firing a laser. As they charge their laser however, the Shield Hunters cannot change their shots' trajectory, giving the player the opportunity to evade them. Also, charging lasers make them put their shields down, leaving them vulnerable.
In the anime series Sonic X, the Laser Hunters appeared during the Sonic Adventure 2 adaptation saga. In this media, they were constructed after the Perfect Chaos incident to combat Dr. Eggman's forces. However, they were never actually seen deployed or in use.
