Epsilon is a hyper-smart computer in Dom's head that acts like his second conscience. Dom has no idea why epsilon is in his head or where he came from, he just knows that he appeared when Dom was reborn a multi. Since then, epsilon has been Dom's strategist and free WiFi provider.
If Epsilon chooses to appear in his physical form he is a tiny robot (about 10 inches tall) that either stands on Dom's shoulder or sits in his afro. Epsilon is white with turquoise eyes, and has a core above his waist. He has a round face that forms almost a cone in the back, he has thick stubby legs and proportionate arms.
Epsilon is very analytic and doesn't really understand human emotions, but is very sarcastic. Epsilon is Dom's A.I. and gives Dom advice and strategy
-Expert battle strategist
-If Dom loses consciousness (i.e. in his multi rage state) Epsilon will take over his body
