Venom: You come in here again, in fact, you go anywhere in this city preying on innocent people and we will find you and eat both your arms and then both of your legs and then we will eat your face right off your head. Do you understand?
Robber: Please.
Venom: Yes. So, you will be this armless, legless, faceless thing, won't you? Rolling down the street, like a turd in the wind. Do you feel me?
Robber: What the hell are you?
[Venom's face partially opens to reveal Eddie's face]
Eddie/Venom: We...are Venom.
[Venom's face fully reforms]
Venom: On second thought.
Robber: Please.
[Venom kills the robber].
Continuity mistake: In the car chase scene when Brock is on the motorcycle going through the city, you can see him pass by the same movie theater at least 3 different times in the chase showing they used the same street over and over while filming.
Answer: Venom was using Eddie, much like Riot, to invade Earth. Venom was damaging Eddie's body until he grew to like him, which is why he said he could fix it while Dan was telling Eddie all of this.
