Though based on E-102 Gamma's core design, the E-1000s are noticeably more streamlined and simplified due to mass-production. Their limbs only feature half the joints used by the original model, and their design lacks a targeting scope, waist-mounted flashlight, cannon-grip and ankle-mounted wheels, implying they lack the original version's ability to change modes. The machine is otherwise identical to E-102 Gamma minus upgrades such as the Jet Booster.
In gameplay, E-1000s act as relatively stationary sentries that will track the player's movements with their cannons. However, the E-1000s' weaponry, with low-velocity projectiles and no homing feature, is generally far less effective than E-102 Gamma's. They obviously lack the intelligence, agility, durability and skill of the original E-102, with their battle strategy limited to simply standing still and continuously firing at the player in an attempt to kill them.
There is another version of the E-1000s which is capable of hovering around instead of just staying on the ground. When destroying any version of the E-1000s, the player is awarded 200 points and an Animal will be released from the robot.
Sonic Rivals 2
In Sonic Rivals 2, the E-1000 makes a cameo appearance as collectible card nr. 80. It is unlocked by achieving the high score in the fight against the Egg Phantom. On their card, they have "1000" written on their side, in the same fashion as the E-100 series.
Powers and abilities
Certain E-1000s have the ability to hover for short distance using small engines attached on their backs. All units also come equipped with a laser cannon without homing features on each arm. These cannons are capable of firing large yellow lasers at low velocities, travelling in tandem as they approach a target, and lacking any sort of guidance system.
In the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics, the E-1000s are mass-produced Badniks and a part of Dr. Eggman's Badnik Horde. The robots, in more recent comics, appear to be more like the E-100 series than their Sonic Adventure 2 counterparts, possessing the same amount of limb joints as standard E-100 units.
