Theme of E-102 Gamma [Sonic Adventure]

Personality & More

Gamma is a serious and rational robot, coldly striving to accomplish his mission. This may seem so at first glance, but in fact Gamma is a self-conscious and noble robot, ready to die for the sake of his friends and family.

At first, Gamma mindlessly served Eggman like all other robots, but thanks to Amy Rose and her help with emotion awareness, as well as an encounter with a bird who was previously part of Gamma’s family, the robot realizes his real mission – to find the other E-series robots and free the animals within them.

In the end, having accomplished his mission, Gamma accepts his own demise in order to allow the bird inside him to be reunited with his own family.

The second model in the E-100 series of shooting robots built by Eggman.

Originally, Eggman’s mech used small animals as their core to extract biological energy, and E-102 also has a small bird inside.

After an encounter with Amy, he begins to question his current form and eventually sets out to save his fellow robots. He and the last remaining robot, E-101, go toe-to-toe, and both regain their original forms in the end.

Incidentally, the reason why the first machine is called “Beta” and the second “Gamma” is because the prototype “Alpha” exists, and “Zero”, who was in charge of capturing Amy at the same time, is the same.

Special Skills

Built-in Machine gun, Roller mode, Flight, Hover.


Gamma is sensitive to water, so he can counter that using his alternate moving mode. Also, Gamma was destroyed because he lost attention in the fight, which shows that his sensors are not perfect.

Biography & Details

Sonic Adventure (1998)
Gamma was created third in the E-100 series and Eggman did not have high hopes for him. Gamma proved his strength by defeating the stronger robot of the series, E-101 Beta in a duel. Soon, E-102 Gamma, E-103 Delta, E-104 Epsilon and E-105 Zeta were given the mission of finding the tailed frog. Gamma excelled, but the other E-series robots disappointed Eggman and were expelled. Gamma was given a new mission to enter the prison compartment of Eggman’s ship and retrieve the blue bird. While carrying out the mission, Gamma got the wrong door and ended up in a room where E-101 Beta was being remodeled into a new form.

After that. Gamma arrived in the prison compartment, but the bird was being held by Amy Rose. She refused to give the bird and accused Gamma of having no feelings. A bewildered Gamma was confused and at that moment, the bird escaped Amy’s hands and flew directly to Gamma. The sight of the bird reminded Gamma of something from his past life and suddenly he decided to free Amy from the cage. A grateful Amy calls Gamma her friend and escapes.

Soon, Eggman calls Gamma to the bridge. Once there, Gamma meets Sonic the Hedgehog and Miles “Tails” Prower, who have arrived to rescue Amy. At Eggman’s command, Gamma attacks the heroes, but Amy stops the robot and appeals to his senses. Gamma realizes that what he is doing is wrong and puts the weapon down. Eggman’s ship crashes and Gamma is forced to flee. Having escaped from the Egg Carrier, Gamma reconsiders his program and decides to save the animals inside the E-series robots, thus betraying Eggman.

After destroying E-103 Delta, E-104 Epsilon, and E-105 Zeta, Gamma arrives on Eggman’s fallen ship and meets in combat with an upgraded version of Beta, E-101 Mark II. Gamma wins the battle, but misses a fatal shot and takes monstrous damage. A bird flying out of Beta’s defeated hull flies up to Gamma and the robot recalls his own family from when he was still free of the metal shell. Gamma decides not to repair himself and simply falls, allowing his own bird to break free.
