E-103 Delta

E-103 Delta (δ) (デルタ) is the fourth of the E-100 Series robots constructed by Doctor Eggman. He appeared in Sonic Adventure, in which he plays a minor role in E-102 Gamma's story as a boss. He resembles the other E-100 Series robots, except that he is silver and blue in color. Delta stands 7'1" (2.15900 cm) and weighs 1819 lbs (825.084521 kg). He has the dual rocket launchers like Beta, but in addition it has a jetpack built into itself for short range flight. Delta also appears in Sonic X.

Along with his brother E-100 Series robots (E-102 Gamma, E-104 Epsilon, and E-105 Zeta), Delta was sent by Doctor Eggman to retrieve Froggy, who had swallowed a Chaos Emerald. When Delta failed to locate the correct frog, Eggman banished him from the Egg Carrier along with Epsilon. He stares at Gamma as he is teleported away, but it is unknown whether any feelings were stirred in the robots.

It is later revealed that he was abandoned at the Windy Valley. Gamma later tracked Delta down, intending to "rescue" Delta by destroying him, thus releasing the animal trapped inside him. The two brothers battled, and Gamma emerged victorious. Delta was destroyed and the animal inside him was freed.

At first, Delta is a clone of Gamma (except for the color), with just one cannon arm and a hand. After being discarded by Eggman, he inherits E-101 Beta's twin missile launchers and jet booster.

In the original Sonic Adventure, Delta's animal was a green Flicky, but in Sonic Adventure DX the animal was changed to a parrot.

Life after Eggman
After he was banished to the Windy Valley by Eggman, Delta lived the remainder of his life there until being killed by his brother E-102 Gamma.

Equipment
Delta has a jet booster, Twin missile launchers and a target locater.

Trivia

 * After Delta fails his mission and is banished to Windy Valley, he takes on the same design as E-101 Beta mk1, just colored blue and with 103 on his side.
 * It can be assumed that Beta's discarded rocket arms were used on Delta.
