After clearing Leaf Storm Act 2[]
[Leaf Storm, day. Sonic is standing in the treetops and faces Eggman in his Egg Hammer Mega.]
- Sonic: Eggman! What are you up to now?

[Blaze jumps away; Sonic looks at her.]
- Sonic: Who's that?
Before entering Water Palace[]
[Zone Map. Sonic meets with Tails.]
- Sonic: Hey, what's up? Eggman's got another crazy scheme, and we saw some mysterious girl... Things are starting to get interesting, eh Tails?
- Tails: Idle hands can be a dangerous thing, Sonic! The ultimate power that Eggman spoke of... I wonder what kind of power he was talking about.
- Sonic: No need to worry! Whatever he decides to do, we'll stop him! Let's go Tails! I know I can always count on you! [Runs off]
- Tails: Uh... Hey, Sonic! Wait for me! [Follows Sonic]
After clearing Water Palace Act 2[]
[Water Palace, day. Sonic is standing in a coliseum and faces Eggman Nega in his Egg Turtle.]

- Sonic: Hey, what's so funny?
- Eggman Nega: I'm sorry, I shouldn't have laughed, but you... You're so cruel... You taunt me by not using my full title. Ha ha ha.

Before arriving at Tails' Workshop[]
[Zone Map. Sonic talks with Tails.]
- Sonic: Wh-what? Did he say his name was Eggman Nega?
- Tails: He looks just like Eggman!
- Sonic: Maybe Eggman just got some new disguise.
- Tails: Even so, Eggman wouldn't change without a reason. Eggman's speech about "ultimate power"... It's really bugging me. Sonic, let's go to my workshop! There's something I want to check out.
- Sonic: Okay, let's go Tails!
After arriving at Tails' Workshop[]
[Tails' workshop. Sonic is waiting for Tails.]
- Sonic: So, have you discovered anything interesting Tails?
- Tails: I-I don't believe it! Sonic! Something's wrong with the space-time continuum!
- Sonic: What?
- Tails: There's a tear in the space-time continuum... and it's expanding! If it continues to expand... the fabric of reality will become altered!
- Sonic: Is this Eggman's work!?
- Tails: I don't know... It might have something to do with Eggman Nega.

- Sonic: Sounds like a good idea. Let's go look around!
After arriving at Cream's house[]
[Zone Map. Sonic and Tails arrive at Cream's house.]

- Vanilla: She's out with a new friend. I don't recall her name, but she had an interesting purple outfit.
- Tails: !
- Sonic: It's gotta be her!
- Tails: Ma'am, do you remember which way they were headed?

- Tails: Knuckles, how'd you wind up getting stuck here?
- Knuckles: (Oh my head!) Wha-? It was because of her!
- Tails: Who?
- Knuckles: That feline with an attitude! I didn't recognize her, but she was with Cream when I spoke to her.
- Sonic: !
- Tails: Where did she go?
- Knuckles: Man, this makes me so angry. I want to punch something! Arrrgh!
[Knuckles punches the rocks blocking the road then leaves in a huff]
- Sonic: K-Knuckles?
- Tails: He's gone, Sonic...

- Sonic: Who are you? Do you know anything about Eggman Nega?
- Blaze: It's none of your business. This is my responsibility, so I'll deal with it.
- Sonic: Hey, that's not how it works around here.

- Blaze: um...
- Sonic: So, there is a relationship.
- Blaze: I said this is MY problem. Don't bother me! [Runs away]

- Sonic: Well... Um, er...
- Amy: What are you trying to say Sonic?
- Sonic: Nothing.
- Tails: Sonic, why don't we ask Amy about Eggman and Blaze?
- Sonic: S-Sure. Amy, have you seen Eggman, or a cat girl called Blaze?
- Amy: A girl? [Clenches fists and makes a horrid face] Please tell me what Sonic needs from this cat girl!

- Blaze: But come to think of it, I can just take your time.
- Sonic: Blaze?
- Blaze: Long time no see, Eggman Nega!
- Eggman Nega: Oh Blaze, my dear. I didn't expect to see you in this world. It seems Eggman has made a mistake.
- Blaze: ... So you guided Eggman to our world.
- Eggman Nega: Ha ha ha. It's best to get someone else to do the dirty work. I've been waiting for him to return with the gems. I couldn't care less what happens to our world.
- Blaze: ... I'll destroy you!
- Sonic: That's pretty harsh.
- Blaze: He's my opponent, Go away!
- Sonic: No can do. There's a few things I owe him as well.

- Sonic: Hey, chill for a second. You're way too tense.

- Cream: Blaze!
- Blaze: ... ... ... Perhaps... Perhaps you're right. I can rely on friends, if I let myself...

- Blaze: I-I'm Blaze. It's nice to meet you too.

- Cream: What will happen to our two worlds?
- Tails: ... I don't know. But I don't think our worlds can co-exist like this. Eventually, everything will disappear.
- Cream: [Crying] No, that can't be!
- Sonic: We've got to come up with a solution fast!
- Blaze: Eggman and Eggman Nega!
- Cream: The two eggheads, right?
