|E-104 Epsilon (Archie)|
215 cm (7ft 1in)
Flight via Jet Booster, retractable legs, missile launcher on right arm
Tasked with locating a frog that had absorbed Chaos' tail, E-104 brought back a random frog, as had two of the other robots. He was transported away with E-101 Beta and E-103 Delta for his failure. After this, E-102 Gamma, who turned against Dr. Eggman, tracked down and destroyed E-104 Epsilon along with the other three E-100 series robots.
- In Sonic Adventure, E-104 Epsilon had two arm cannons like E-103 Delta after he was rebuilt, whereas in the comics he was only shown with one arm cannon.
- Epsilon's name was never specified in the comics, though his number was present.
