This is the script of Super Sonic's story in Sonic Adventure: Chaos Unleashed.
Tornado 2 and the Chaos Emerald
[The cutscene begins with the Chaos Emerald in the Tornado 2 as the wrecked aircraft sits in the water next to Big's house in the Mystic Ruins and ends here.]
[Eggman, Orbot, and Cubot are at the jungle.]
Eggman: Ooooh... I hate that Sonic! He always seems to get in my way! But I bet he can't foil my master plan.
[The trio sees Chaos in his puddle form.]
Orbot: Is that Chaos?
Eggman: He has returned! Only in his normal form.
Cubot: Looks like we'll have to find all the Chaos Emeralds all over again.
Eggman: And we are! Alright, Chaos, let's begin searching--
[Chaos attacks the three.]
Angel Island Falling Again
[Angel Island is suddenly falling down.]
Knuckles: The Master Emerald is where it belongs. But Angel Island is still falling! This doesn't make any sense. Maybe... [Looks at the 6 Chaos Emeralds lying against the Master Emerald.] Those Chaos Emeralds... that I brought back with me... have something to do with what's happening. I'll take them to Sonic for his advice. [Sees Eggman, Orbot, and Cubot far ahead] Eggman! [Comes to see the three] Why are you guys lying here? Are you trying to pull another one of your tricks!
Eggman: No, Knuckles... This is terrible! Ch-Chaos is...
Knuckles: Is what?
[Chaos appears and attacks Knuckles.]
Rush to Angel Island
[Sonic is resting at a tree.]
Sonic: *Yawning* Guess Eggman's learned his lesson... yep! And maybe I'll take another vacation somewhere.
Sonic: Hey there, Tails! Did you find the Tornado 2?
Tails: Never mind that. Get up and follow me. Angel Island is falling again!
Sonic: Hey, no way! Who blew it this time?
Tails: I don't know, but we'd better hurry!
To the Past Again
[Sonic and Tails rush to find Knuckles, Eggman, Orbot, and Cubot]
Sonic: Knuckles! And Eggman? What happened here?
Knuckles: Sonic... uhhh, sorry! We were all attacked by Chaos.
Tails: He's still alive?
Knuckles: Yeah. And he stole my Chaos Emeralds!
Eggman: Aaarrgh! He's not gonna get away with this! I'm not going to stand here and let that beast defy me! I will deal with this myself! Farewell, you fools!
Knuckles: Hey Eggman! Wait up! Sonic... Chaos is a fearsome beast! If he gets that last Chaos Emerald, we're done for!
Sonic: No need to explain, we'll get on it! It should still be on board the Tornado 2! Tails?
[The light suddenly shows up]
Tails: There's that light again.
Knuckles: What now?
Sonic : Wha...?! Aw, Gee...!
[The screen fades to white.]
Night of Horror
[Sonic and Knuckles are taken to the past where the shrine of the Master Emerald is in flames.]
Sonic: This place... It looks familiar!
Knuckles: You seen this too?
Sonic: Yeah. It's not a dream, after all.
[Sonic and Knuckles see a group of echidnas led by Pachacamac standing in front of the shrine; Tikal stands in their way.]
Pachacamac: Get out of my way!
Tikal: No way!
Pachacamac: Did you hear what I said?
Tikal: I won't obey!
Pachacamac: We need those 7 Emeralds to give us total power! It's power for the people! And they are your people too, you know! We must get that Emerald!
Tikal: Greed is our enemy! Once it starts, you will always want more! Please don't do this. I beg you!
Pachacamac: Bah! I don't listen to the words of a child. Ready, men! Charge!
[The Altar of the Emeralds comes under attack from the Knuckles Clan, who knocks Tikal to the ground and injures many Chao. Sensing what happened, Chaos becomes infuriated. The Chaos Emeralds circle the Master Emerald, then Chaos rises to confront Pachacamac and his soldiers as they reach the Master Emerald, causing them to recoil in fear.]
Pachacamac: Aaaaagh! It's a monster! [Chaos unleashes its wrath on the Knuckles Clan and everything whites out] Noooooooo!
[Sonic and Knuckles head over to Tikal to see if she's okay.]
Sonic: Hey, are you all right?
Tikal: Uh... I think so. Oh my gosh! No!... No!... No!... I must put a stop to this now!
Sonic: Wait up!
[Tikal goes to the shrine and Sonic and Knuckles follow her.]
Tikal: The 7 Emeralds are the servers. Chaos is power, enriched by the heart. The controller serves to unify the chaos. Uhh... The 7 Emeralds can change our thoughts into power. If this Emerald controls that power... Please, you must stop him!
[A green light flashes the screen]
Return to the Present
[Sonic and Knuckles return to the present.]
Tails: Sonic! Knuckles! Wake up!
Sonic: Ahhh... we were on a snooze cruise, I guess!
Tails: Good thing you're okay. You just sort of conked out, there.
Knuckles: I think this is all making sense to me, guys. I think I remember what I've learned in the history of my race. 4,000 years ago, my race plotted to steal all the Chaos Emeralds to combat against their rival, but due to their attack on Tikal and the Chao, this angered Chaos and he used all 7 Chaos Emeralds to kill most of the echidnas.
Tails: So he did used them before.
Sonic: That's probably how the mural described it.
Knuckles: So Tikal used the Master Emerald to seal back Chaos. And fast forward to now, the Master Emerald shattered and Chaos was released from within. Thanks to Eggman.
Tails: That explains everything.
Sonic: Come! We gotta go after the last Emerald!
Tails: Lead the way!
[Sonic, Tails, and Knuckles find the Tornado 2 at Big's Hut]
Tails: Look It's the Tornado 2!
Knuckles: Yeah, so let's get the Chaos Emerald and leave!
[Before the trio could get to the Emerald, Chaos arrives and takes it]
Sonic: What? No! He's got the last Emerald!
Tails: Now what do we do?
Station Square Destroyed
[Station Square is hustling and bustling with traffic and pretty much another normal day. In the sewers under the city, the water begins to ripple and soon begins to form into waves that have the troughs between them become deeper and deeper. Above, no one is aware of what's happening. Back in the sewers, water begins to flood the tunnels, while above ground, manhole covers begin to be blown clean into the air as water erupts from them, causing panic as cars screech to a halt to avoid hitting the geysers, the streets begin to crack and fissure, and water begins to blast out of buildings, shattering windows and flooding the streets before a huge tsunami roars over the buildings. When it is all over, the city is now a flooded wasteland. Several windows on one wrecked building continue to blow out before a huge rush of water bursts out before reforming into the head of Perfect Chaos. The beast lets out a loud roar before zooming in on its eye as it opens to look around with its reptilian pupil.]
Sonic: If I wasn't just dreaming, that monster is a real menace! [Spots the Egg Carrier 2] Eggman! And he's got another Egg Carrier! Looks like he's after Chaos, too!
Eggman: [Inside the control room] This Egg Carrier 2 was made because something like this could happen. You have defied your master, stupid beast. Now you must be destroyed at all costs! Charging up the laser beam!
[Eggman starts to fire up a laser beam, but Perfect Chaos shoots a laser beam from the mouth, destroying the Egg Carrier.]
Eggman, Orbot, and Cubot: Aaaaahhhhh!
Sonic: I've had enough! Who do you think you are, anyway?
[Tikal's light approaches to Sonic]
Sonic: Oh, it's you! The one who sealed Chaos in the Master Emerald! Tikal!
[Tikal appears in a physical form]
Tikal: My heart has always been in the Master Emerald, along with Chaos'. Now he's filled with anger and sadness. And if it goes on, he'll eventually destroy the world, like he did before!
[Perfect Chaos discards the Chaos Emeralds, which lost its power. One Emerald drops in front of Sonic.]
Sonic: The Emerald lost its color.
Tikal: Look! he's absorbed the Emerald's power! He must be sealed in the Master Emerald, NOW!
Sonic: How can that help? It won't change how he feels inside, will it? His heart will still remain in turmoil and his anger just won't vanish! He'll just be trapped forever!
Tikal: What choice do we have?
[Tails, Knuckles, Amy, Big, Cream, and Vanilla find the other 6 Emeralds.]
Amy: [Holding the Emerald] Hey, Sonic!
Amy: [Gives Sonic the Emerald] Here, take this!
[The others arrive with the other Emeralds]
Sonic: Hey guys, what's up?
Tails: [Holding the Chaos Emerald] Chaos only used the negative power of the Emeralds. Sonic, you should be able to harness their real power! [Gives Sonic the Emerald]
Knuckles: [Gives Sonic the Emerald] As much as I hate to admit it, I think Tails is right about this!
[The others give Sonic the rest of the Emeralds]
Sonic: Thanks, you guys.
[The Chaos Emeralds start glowing and regaining their color]
Cream: The Emeralds are glowing!
Vanilla: I see, Cream.
Tikal: But I thought the Chaos Emeralds' power would be awakened through hatred and anger.
Tails: Negative forces aren't the only way to empower the Chaos Emeralds. Our positive feelings toward each other can make them work. Our hearts together form awesome power.
[Sonic closes his eyes and uses the positive feelings of his friends and the citizens of Station Square to transform into Super Sonic. He then flies off to engage Perfect Chaos in battle.]
Sonic: Chaos! I'm gonna free you forever!
[Chaos is reverted to his normal form, Chaos 0. He spots several of his organic kind, the Chao, and knows of their peacefulness.]
Knuckles: Chaos has changed again. This time for the better.
Tails: Yeah! Super Sonic must have neutralized it, so it's nice again.
Sonic: He's a free creature now.
[Cheese flies up to Chaos along with the Chao]
Cream & Vanilla: Cheese!
Cheese: Chao! Chao! Chao!
Tikal: [Arrives before Chaos.] These are the Chao you were protecting. They stayed alive for generations and now live peacefully with humans. The fighting's over. Harmony's restored, and life goes on. [Turns to Sonic and his friends] Thank you so much!
[The others nod]
Tikal: Come, Chaos.
[Tikal and Chaos levitate into the air and disappear in a flash of light. Sonic notices Eggman flying away.]
Cubot: Boss, why are you leaving Station Square? You said that you want to build Eggmanland on its ruins.
Eggman: I can't build it if it's flooded! I'll just go and devise a new plot.
Orbot: Which will most likely backfire on you much like what happened with Chaos.
Eggman: [Smacks Orbot on the head] You smart-mouthed bucket of bolts!
Tails: All's well that ends well, right?
Amy: But Station Square is destroyed. I might want to find a new place to live.
Cream: [Notices that Sonic is missing] Where's Mr. Sonic at?
Amy: Oh! He ran off again!
Tails: Well, that's Sonic for you.
Sonic: [Jumping between the buildings] Whatever your next plan could be, Eggman, I'll foil it Sonic style!
