Shadow Android

Shadow Androids (シャドウ・アンドロイド) are robots created by Doctor Eggman that resemble Shadow the Hedgehog. They first appear in Sonic Heroes seen in tubes and again in Shadow the Hedgehog as enemies. They rival Shadow's abilities almost completely and they never attack alone. They shoot with missiles from their hands as to hone all of Sonic and Shadow's physical combat skills, but are incomplete, and are very buggy in close combat, but can still make up for it in high speed battles. Eggman apparently discontinued the production of these robots, and the reason for this is unknown. Presumably, E-123 Omega could have destroyed so many of them that he had none left after the events of Shadow the Hedgehog, or he couldn't make anymore because he himself had ordered Team Chaotix to destroy as many of the tubes they were stored in as they could find. Shadow Androids could be analogous to Shadow as Metal Sonic is analogous to Sonic except Shadow Androids look exactly like Shadow. They appear to have no ability of speech. However, the Multiplayer Androids of Shadow the Hedgehog were able to speak. The ones that can speak all similarly mimic the real Shadow by calling other "fakers."

Sonic Heroes
The Shadow Androids made their debut in Sonic Heroes at the ending of Team Dark's story. After the trio had defeated Dr. Eggman and his Egg Emperor (really Metal Sonic pretending to be Eggman), Rouge the Bat went in search of the Doctor's rumored treasure trove on the flagship of the Egg Fleet. What she found was actually a room packed with row after row of Shadow Androids suspended in tubes just like the one she'd discovered the real Shadow in. E-123 Omega then walked in and stated his intention to destroy the entire place, but before then, he revealed to a distraught Rouge that the Shadow Androids were part of a cloning project by Eggman, and that the original must exist somewhere. With this new information, Rouge left Omega to his work. Whether Omega successfully destroyed the room and its Shadow Androids or got side-tracked after the Metal Overlord appeared is unknown.

Shadow the Hedgehog
The Shadow Androids reappeared serving Eggman as part of his army in Shadow the Hedgehog. They first appeared in the Iron Jungle stage, and Shadow came face-to-face with a troop of them while they were receiving their orders from Eggman about how to take care of the Black Arms. The Shadow Androids mainly appeared within rooms of the Iron Jungle base and attacked the real Shadow in groups of three and later tried to assist Eggman when he battled Shadow and Omega in his Egg Breaker. They then tried to keep out Shadow when he infiltrated Eggman's Lava Shelter in his new quest to destroy Eggman.

Multiplayer
In the multiplayer mode of Shadow the Hedgehog's self-titled game, five robotic versions of Shadow, along with the real Shadow the Hedgehog, were allowed to be played. They all claimed to be the real Shadow, and that the others were fake. One was simply a Shadow Android with yellow stripes, gloves, and shoes. The others were silver, resembling Metal Sonic, but with different stripe colors ranging from blue, orange, pink, and green. Two of them had a modified grenade launcher and the other two had rapid-fire machine-guns, and the weapons were non-removable, while they had infinite ammunition. However, it is debatable if the yellow android was really a robot, if the red one was really Shadow and if they were created by Eggman or not.

Abilities
Shadow Androids seem to have all the physical capability of Shadow and can take more damage than the average Egg Pawn. They fire tracer missiles from their hands and can defend themselves from physical attack by jumping and mimicking the homing attack, so the only way to defeat them is with a weapon or the spin dash. The Shadow Androids seem to be the only enemies that Shadow encounters that are resistant to punches or kicks.

The multiplayer Shadow Androids can move at great speed just like Shadow. The ones that look more organic can use a variety of weapons, while the metal ones have unlimited ammunition in the form of bullets and explosive shells. The colors of the Androids can be red like Shadow, or tan. The robotic Shadow Androids can range from a color such as pink, blue, green, and orange. However, the robotic Androids cannot pick up any weapons, as the weapon they use is merged into their arm, disabling the use to pick up another weapon. Also the Shadow Androids appear to talk identically to the real Shadow Unlike many other of Eggman machines like Metal Sonic, Omega And E-123.
