- Main article: E-100 Series
Unlike many of Eggman's robots in previous games, the E-100 series were important characters in their own right. The most prominent was E-102 Gamma, who was a playable character during the game. The others served as bosses, with the exception of the mass produced Egg Keeper, which is a standard enemy robot.
The E-100 Series robots from Sonic Adventure include:
- E-100 Alpha, "ZERO"
- E-101 Beta (Later remodeled as E-101mkII)
- E-102 Gamma
- E-103 Delta
- E-104 Epsilon
- E-105 Zeta
- Egg Keeper A mass produced robot that captures the player with energy rings. Said to be an E-100 Series robot in the instruction manual.
