E-102 Gamma

E-102 Gamma is the second robot of the E-100 series line was created by Dr. Eggman. Gamma is powered by a captured pink Flicky held inside the robot. Although Gamma was created by and made to work under Dr. Eggman, assisting in empowering the Chaos creature, he turns against his maker's will

History
His first task given to him by the doctor, involved capturing a frog who had absorbed Chaos' tail (namely Big the Cat's pet "Froggy") in a contest against his younger brothers, E-103 Delta, E-104 Epsilon and E-105 Zeta, with Gamma being the victor. (StH: #80, #82)

Eggman then tells Gamma, now his favourite robot, to acquire a bird from a girl held captive in a prison cell on the Egg Carrier. (StH: #82)

After finding Amy, Gamma demands the bird only for Amy to bluntly refuse, her affection toward the animal confusing him. The bird then flies up close to Gamma. Somehow affected by this, Gamma suddenly experiences an unbearable pain, before suddenly freeing both Amy and the bird from their cell, urging them to leave.(StH: #82)

Surprised and touched by this, Amy exclaims that Gamma must be different from the other robots.(StH: #82)

Gamma has little time to deduce what he has just done before he is called up to the deck to dispose of the trespassing Sonic and Tails. (SSS: #13)

A grueling battle ensues, but Amy stands in between them, begging them to stop and explaining to Sonic that Gamma is her friend. Both reluctantly submit to Amy's pleas and back down. As the Egg Carrier begins to lose altitude and slowly fall to the earth below, Amy encourages Gamma to free himself, explaining the virtues of friendship before they evacuate. (SSS: #13)

Personality
Like most of Eggman's robots, Gamma has a free will and personality, though unlike over-ambitious models such as Metal Sonic, Gamma's leave of duty is usually out of a compassion or remorse for his actions against Sonic and his friends.

Gamma is renowned for gaining his sentience and more or less being the first to portray the thoughts of an average Eggman robot. However, given his mindless actions as Eggman's slave, it is unknown if he gained sentience or had it all along but simply disregarded it at first. Even under evil alignment however, he holds a sensible and rational manner towards his enemies. However he becomes somewhat uncomfortable to vivid human emotions, to the point that the emotional conflict of his loyalty pains him, leading to his eventual leave of duty.

It should be noted that even when gaining a free will, Gamma still holds a rather regemented attitude and devotion to his mission. He considers his life less important than his friends' and is shown to fight selflessly for them to the brink of sacrificing himself, much like other heroes in the series, the only difference being that Gamma was actually given such an opportunity.

Abilities
As one of Eggman's destructive gunner robots, E-102 is built for battle. His main weapon is a machine gun that cam lock-on with help form a laser targeting device on his head.

Due to the targeting device, Gamma's shots are always accurate and allows the pinpoint accuracy to find an enemy's weakspot.

Gamma is also equipped with a jet booster that allow him to hover for some time and cross longer distances in the air.

Background information
According to current head-writer Ian Flynn, Gamma remains alive but unseen and has hinted at him reappering in Sonic Universe.
