In this desert island, Dr. Robotnik is planning his attack in Gotham. The city is unlike any other, but it should be easy to dominate. Nothing that some killer robots couldn't handle.
Orbot: Master Robotnik, is the plan ready?
Dr. Robotnik: Almost. Is Metal Sonic fixed yet?
Orbot: Well… not quite.
Dr. Robotnik: What do you mean "not quite"?!
Orbot: He was damaged in the anomaly with the Chaos Control, his system appears to be destroyed. It will take quite a while to rewrite the kernel.
Dr. Robotnik: (sarcasm) Great. Wonderful! Anyway. Let's begin our plan of conquest.
Cubot: What robot will you use?
Dr. Robotnik: While Metal Sonic is down, we will need to use another army. At least the Badniks kernel is still intact. (opens a program in the computer to choose a robot) There's too many… Who will I choose? (hits the "Random Selection" option)
The computer decides a random robot for the attack. After 5 seconds, the result is finally out.
Dr. Robotnik: (looking at the selected robot) Oh. Great! The Kill-850tk army.
Meanwhile… in The Joker's base…The Joker is reunited with some of Gotham's most dreadful villains. They are in a reunion about the weird robot appearances and the weird creatures invading Gotham. They're creating a plan to take this situation to their advantage.
The Joker: Hello, dear friends, you probably know why we're here.
Harley Quinn: To talk about a cute hedgehog!
Mr. Freeze: Wait, what? To talk about that? Are you kidding me?!
The Joker: No, shitheads. We're talking about those robots attacking Gotham and three weird craetures who The Riddler and The Penguin saw.
The Riddler: We saw three weird things in the heist of the Gotham City Bank. One resembled a giant blue hedgehog, other resembling a two-tailed fox and another one looking like a red gremelin.
The Penguin: "Gremelin"?
The Riddler: I don't know what that thing was, other than it was red.
Poison Ivy: I've seen hedgehogs and foxes, but I didn't saw one like those things you're talking about.
The Joker: Are you sure, Dr. Pamela?
Poison Ivy: What are you talking about?
The Joker: Those things resemble something you may have created. Or you, Dr. Victor.
Mr. Freeze: I think you are inhaling too much of your laughing gas. If I created those things I would not be here. Also, I have more important things to do.
Two-Face: (mumbling) Like saving your wife…
Mr. Freeze: I heard you! Do not mock my pain or else-
The Joker picks a gun and shoots on the ceiling. The gun's sound echoes throughout the base, that is almost falling apart. Everyone shuts up.
The Joker: Everyone shut the fuck up! We have more important things to worry about. Those attacks are calling Batman's attention, and those creatures may be allied with him, or even better, we have a third party involved on this game of chess. We have some things to prove this.
The Riddler: Yes, we've found this strand of hair while we were on the heist.
The Riddler puts the strand of hair on the table. It's another piece of Sonic's hair. Mr. Freeze picks it up. Mr. Freeze starts to examine the strand of blue hair.
Mr. Freeze: (hmmm) This looks like fur. But what kind of fur?
The Riddler: From the giant blue hedgehog creature. We may have someone else involved on this. We never saw those things before.
Two-Face: Batman probably doesn't know those things. And he sent the Gotham City police after Victor, Pamela and Jonathan.
Mr. Freeze: What do they want with us? And with Scarecrow?
Two-Face: They think you three are responsible for this.
Poison Ivy: All right. Let's show Gordon and Batman they're wrong!
Harley Quinn: Yes! Let's crush their skulls!
The Penguin: No. If we reveal ourselves, they will overcome our plans. We need to be furtive. And this "third-party" cannot escape. We need to investigate those events and discover the "third-party's" plan. We should stay quiet for the moment.
The Joker: Okay, "birdie who can't fly", what do we do?
The Penguin: First, we need to rescue Scarecrow. He's currently in Arkham. And after that, we need to capture those things. We can use their powers to overcome Batman and destroy the "third-party invader".
Mr. Freeze: That will be easy.
The Penguin: We will not kill them.
The Joker: What?! Why?!
The Penguin: We can kidnap them, take their power and demand a quantity of money so that the "third-party invader" appears and reveal his plan to us. Does everyone agree with this?
Everyone: This sounds good.
The Penguin: All right. Now, we need to save Jonathan.
Mr. Freeze: I also discovered another thing.
The Penguin: What is it?
Mr. Freeze: I discovered a weird energy anomaly on a desert island in the sea of Gotham. Maybe that's something that the "third-party invader" is doing. We could investigate that.
The Joker: All right. Let's begin, bitches.
Harley Quinn: Yay! (clapping)
A few hours later, in the heart of Gotham…In the heart of Gotham, everyone is walking, minding their own business. It's like a colony of ants, where everyone is doing the same thing. Going to work, buying things, going back home, etc. Nothing interesting. Gotham City is not different from any other city on the world. It's the same thing, everyone is being controlled by the society.
In this moment, a pickpocket steals a woman's purse. Nothing special, this happens all the time. When the thieve is running away, the earth starts to shake. Everyone gets startled. It's not an earthquake. It's something else. Everyone looks at the sky and sees an army of Badniks. Like anyone would do, they all run away.
The Badniks land on the streets and Dr. Robotnik appears on his Eggmobile. He orders the robots to attack. The robots start to attack the city. Crushing cars and shooting buildings. The police shows up a few minutes later, but they are not being able to handle the attack.
In the Gotham City National Park…Sonic, Knuckles and Tails wake up. They start to eat some of the junk food that Sonic has stolen a few days before. But their lunch is quickly interrupted by the attack from the Badniks. Sonic, Tails and Knuckles easily destroy the robots, but they see more robots attacking, and it's coming from the east, the localization of the heart of Gotham City. They rush to the city, to destroy the robot menace.
Meanwhile, in the heart of Gotham…The mayor appears to have a little talk with Robotnik, since Robotnik is calling the mayor.
Mayor: All right, stranger, since you called me, I'm here. What do you want?
Dr. Robotnik: Hello, mayor. All I ask is that you give me your city.
Mayor: Or else?
Dr. Robotnik: "Or else" this! (snaps his fingers)
The army of Badniks destroy a building close to them. The building falls apart.
Dr. Robotnik: Now. What's your decision? Will you give me the city?
Mayor: I'm sorry, but I can't do that.
Dr. Robotnik: (sighs) All right, then. Destroy them all.
Before Robotnik snaps his fingers, he's hit by a batrang. He almost falls out of the Eggmobile, but he is able to hold on. It's Batman and Robin.
Batman: All right, whoever you are. You will stop.
Robin: These robots again?
Dr. Robotnik: Well, well, well. You two are the targets. Great. Now you will be destroyed. Kill them! (snaps his fingers)
The robots start to shoot the building. Batman and Robin jump down from the building and try to attack the robots. They try using all their gear and firepower, but it doesn't appear to work.
Batman: What do we do now?
Robin: (sarcasm) If only those creatures could appear and help us…
When the robots try to get closer to Batman and Robin, one of them gets destroyed by a dark blur. Another one gets destroyed by a flying hammer.
Robin: (sarcasm) Well, look at that. How convenient.
The dark blur reveals himself. It's Shadow.
Batman and Robin: That thing again?
Shadow: Looks like we've met again, Robotnik.
Dr. Robotnik: Shadow?
Another one of the creatures show up, it's Amy Rose.
Robin: Now that's a new one.
Amy Rose: (picks up her hammer) All right, Robotnik! You will give Cream back!
Dr. Robotnik: Too bad, you little brats! I do not have her! She disappeared!
Robin: Who's "Cream"?
Shadow: All right. If you're not give her back, we will destroy your robots.
Dr. Robotnik: I'd like to see you try. (snaps his fingers)
Shadow starts to attack the robots. But before Amy goes to attack them, Robin calls her.
Robin: Hello, there.
Amy Rose: (picks her hammer) Who are you?
Robin: I am Robin. And that one is Batman. And I guess we are on the same side. We both want to destroy those robots.
Amy Rose: Okay. Let's go!
Amy runs off.
Batman: What are you doing, Robin?
Robin: Don't you see, Batman? They are in our side. It's better we ally with them, or just die.
Batman: All right. We're gonna ally with them.
Batman and Robin go fighting with Shadow and Amy Rose. The fight is very hard, even though Shadow and Amy know how to defeat those robots. Batman and Robin barely make a dent on those robots. When they almost defeat them all, Amy gets captured by a robot arm.
Shadow: Let her go!
Dr. Robotnik: Let me think. Hmmm. No! Now listen, if you don't surrender yourselves or the city, this rascal will be crushed to death!
The robot slightly presses his hand, making Amy scream of pain.
Robin: What do we do now?
Batman: We don't even know her. Why should we care?
Dr. Robotnik: I will give you three 3 seconds to decide. Either she dies, or you surrender. 3…
Shadow looks at Batman and Robin. They don't know how to solve this situation.
Dr. Robotnik: 2…
They still don't know what to do.
Dr. Robotnik: 1!
A blue blur appears and destroys the robots.
Dr. Robotnik: What the…
Robin: They're back!
Dr. Robotnik: Sonic!
Sonic: Hello there, egghead!
Dr. Robotnik: Kill them all! Don't let anyone live! (snapping his fingers real fast)
Sonic destroys the robots. Tails is able to save Amy and hack the Badniks operating system. Tails makes the Badniks pick Robotnik's Eggmobile and destroy it. Robotnik falls on the ground. But he makes another robot mobile appear, and so he runs away.
Dr. Robotink: (running away) This is not over! I will be back!
Robin: Come on! Another cliché! This is getting annoying!
Tails: (flies down with Amy on his hands) Are you okay?
Amy: Yes, thanks!
Sonic and his friends look at Batman and Robin.
Sonic: (talking to his friends) Let me talk with them. (talking with Batman and Robin) Hello, my name is Sonic. And as I could see, you two, Batman and Robin, are in our side.
Batman: I guess so. Who are you?
Tails: I'm Tails. These are Knuckles, Shadow and Amy Rose. We are not from here.
Batman: What are you talking about?
Tails: We are from another universe. An anomaly has caused us to be transported here. We are not your enemies. We're just lost.
Robin: And who was that?
Tails: That was Doctor Ivo Robotnik. He's an evil dude. He's trying to kill us and as you could see, dominate this city, and eventually, this universe.
Batman: And what are your intentions?
Sonic: I saw that you're also trying to stop Robotnik. We could make an alliance. If we get back home, Robotnik will be destroyed. I'm not obligating you two to ally with us. I'm just asking.
Sonic reaches his hand to Batman. Batman gives Sonic a handshake.
Batman: So, what do we do now?
Sonic: Take us to a secure location. We need to discuss about a plan.
End of the chapter seven…
