Mario and Meggy kept searching for enemies to kill, until they came across something even worse.

Meggy: Oh my god...

Mario: What is it?

They ran over to a few dead corpses of Inklings. They screamed at what they saw.

Mario: OH GOD, THEY'RE DEAD!

Meggy: Who did this?

Infinite flew over to them and saw the corpses.

Infinite: Holy shit. I know who did this. I recognize those scars from anywhere.

Mario: Who is it?

Infinite: Sonic.exe.

Suddenly, the sky turned red with a clap of thunder.

Infinite: Oh no. He's around here.

Mario and Meggy shivered in fear.

Infinite: Don't be scared. We'll overpower him and take him down. Don't let fear get to you.

Meggy: Yeah. He's right, Mario. We'll take that murderous hedgehog down.

Mario: Let's both stick together.

Meggy: Okay.

Mario and Meggy held hands and started to look for the evil hedgehog. As they were finding him, they saw a couple more Inkling corpses. One was barely alive and Infinite was talking to it.

Almost-dead Inkling: Please... protect everyone. I want that hedgehog dead... then my... family... will be safe.

The Inkling died, as Mario and Meggy got scared again.

Infinite: You'll be fine. We'll take him down.

Meggy: Right, Infinite.

They went back to searching for Sonic.exe, and after a few minutes, they saw Sonic with his eyes closed.

Mario: Oh look. It's Sonic. Maybe he'll help us out.

Meggy: Hey, Sonic!

Sonic didn't answer.

Meggy: Sonic!

Mario: Maybe he'll answer if we come close to him and touch him.

Meggy: Yeah. Good idea.

As they walked over to Sonic, however, they heard a small static noise.

Meggy: What's that noise?

Mario: Ignore that. We need his help.

As they walked closer, the static gets a little louder and louder, until finally, once they got close to him, he opened his eyes...

and Mario and Meggy blacked out.

It was then that they realized, they found the wrong Sonic.

They both woke up in a completely different place, which looked like Green Hill.

Mario: Meggy?

Meggy: I'm right here.

Mario: WHERE ARE WE?!

Meggy: I... I don't know... but I'm scared.

Mario: Infinite! Reader! Anyone!

Meggy: Hold me, Mario.

Mario: I'm more scared than you are.

Meggy: So am I.

They both went silent. Then they started to shed some tears and hug each other.

Meggy: Maybe we'll get back to Inkopolis once we go through this.

Mario: Yeah. That's gotta happen.

They started walking through Hill, and they keep seeing dead corpses of animals.

Meggy: Just try not to look at the dead bodies, Mario.

Mario: We'll be out of here soon.

Unexpectedly, the area was now on fire.

Mario: Woah. Well that came out of nowhere.

Meggy: Let's just continue walking. We gotta get out of here.

In under a minute, the music around them started to get more stressful and fast-paced. Meggy looked behind her and she saw Sonic.exe running to her and Mario.

Meggy: Mario, run! Just run for your life!

They both ran as fast as they could, but 10 seconds later, Sonic.exe caught them.

Sonic.exe:

Sonic.exe stabbed them with his claws, and he didn't kill them... but he changed them.

Back at Inkopolis, Infinite, along with Meggy's Violent Ruler, female Pikachu, and Meicoomon were walking alone looking at the red sky.

Infinite: The demonic energy is off the charts. He's absorbed a lot of souls... and I sense two more demonic beings around here.

Machito, the male Pikachu, JCR, and Edgellie saw them and ran over to them.

Machito: Hey, Infinite. Why is the sky red?

Infinite: Oh hey, Machito. I told you about this before, but I sense that Sonic.exe is around here somewhere.

JCR: I see that the two Pikachus missed each other.

The Pikachus were hugging each other.

Edgellie: So cute!

JCR: Wait, Sonic.exe is real?!

Infinite: Yes, and he's close, so we better watch out, because he can appear at any moment.

Sonic.exe:

They got scared by his sudden appearance, and they saw Mario and Meggy with their eyes closed beside him.

Infinite: Mario? Meggy?

Sonic.exe:

Mario and Meggy opened their eyes, as they are now bloodshot like Sonic.exe's.

Everyone: Mario! Meggy! No!

Sonic.exe:

Infinite: You sick bastard! Those are our best friends, and you turned them into monsters of your creation!

Sonic.exe:

???: No it isn't!

Everyone turned around to see who said that, and it was Clauds.

Clauds: Nobody possesses our friends!

Machito (thoughts): There she is. Don't freak out, Machito. Don't openly express your love to her yet.

Sonic.exe:

The real Sonic ran in and stood beside Infinite and the others.

Sonic: Did somebody call my na... WHAT THE HELL IS THAT?!

Sonic.exe:

Infinite: Your reign of killing innocent people comes to an end. Ready, guys?

Sonic: You two try and survive Mario and Meggy's attacks. I'll take care of this heartless faker!

Sonic.exe:

Sonic and Sonic.exe started running all around Inkopolis to see who's the fastest. They're both the same speed, but Sonic.exe has another trick up his sleeve. He teleported and appeared in front of Sonic, grabbed him by the neck, and threw him to a building.

Sonic: He's... too skilled.

He passed out, and while that was happening, Mario.exe and Meggy.exe were trying to kill their friends because they were in Sonic.exe's control. Infinite and his friends tried to jog their memories and remind them of the good times, but that didn't work at all. Sonic.exe ran back to see this.

Sonic.exe:

Infinite: Bring it on, Exe. Ugh... uuuuuuggghhhh...

Infinite started to go through a transformation, and he turned into Dark Infinite.

Dark Infinite: Let's end this, you soulless monster!

Clauds: We're right behind you, Infinite.

Clauds got out her Splat Roller of Eternal Fury, Machito got out his Wind Sabers, both Pikachus started to power up their shocks, JCR got out his Lightsaber of Endless War, Edgellie got out Serenity's Dualies, and Infinite got his fists ready to punch Sonic.exe.

They all ran at the demonic hedgehog, but they only managed to hit him half the time. He kept speeding away to dodge the attacks and shots, but other than that, they did a pretty good number on him. However, he had the same power Mephiles has.

Sonic.exe:

Infinite: Oh no. I don't know if we'll ever make it or not.

Machito: I wonder if he has a weakness. Maybe then, we'll actually beat him in this battle.

Infinite: You're right. He's gotta have a weakness.

Infinite thought this in his head for a while, and he finally found an answer.

Infinite (thoughts): Sonic.exe is a demonic hellspawn... the opposite of hell is heaven... Holyness is something that the devil hates, and Meggy was given the Holy Hand Grenade one time!

Infinite: Clauds! Look in Meggy's Widowmaker. She's gotta keep her stuff in there. Find a Holy Hand Grenade.

Clauds: Okay, Infinite.

She went to the Widowmaker and inside the compartment she saw a bomb with a Christian cross on top of it. It was the Holy Hand Grenade.

Clauds: I found it!

Infinite: Good, now throw it at Sonic.exe! Now!

Clauds: The power of Christ compels you!

Clauds threw the Holy Hand Grenade at Sonic.exe, as it started to burn him once he touched it. He let out a demonic scream as the Holy Hand Grenade blew up with a huge shockwave, killing Sonic.exe instantly and bringing him back to the depths of hell. Machito was freaking out on the inside once he saw that.

Machito: Great job, Clauds.

Clauds: Thanks.

Infinite: The beast... is finally gone.

Mario and Meggy started to turn back to normal, as they started to wake up.

Mario: Where are we?

Meggy: We're... alive? And back in Inkopolis?

Mario and Meggy, as well as everyone else, were so happy for them to be back. The married couple hugged each other tightly, as they now wondered what happened.

Infinite: What happened with you two that caused you to be under Sonic.exe's control?

Mario: Well, we saw him with his eyes closed and we thought that it was the real Sonic.

Sonic came in bruised and tired.

Meggy: Sonic. What happened to you?

Sonic: That demon version of me bashed be into a building.

Mario: Oof. That must've hurt bad. You should take a rest.

Sonic: You're right. Thanks.

Meggy: Anyways, that fake Sonic opened his eyes, and we blacked out. We woke up in a colourful place, but we heard creepy music around us.

Mario: We needed to go back to Inkopolis, but we thought we had to go through wherever we are in order to get back.

Meggy: Just then, the entire place was burning and we saw Sonic.exe chasing after us. We got caught by him... and we got stabbed by it's claws.

Mario: We were now under his control. We weren't able to control our bodies. We kept calling for help, but you couldn't listen to us.

Meggy: It was horrible being controlled. We just wanted to go back...

Meggy started to cry, and so did Mario. What they experienced was just too scary for them.

Infinite: It's okay, you two. He's gone for good. Maybe you two need a rest to calm down.

Mario: Good idea.

Meggy: Let's try and forget about... what just happened.

Infinite took them to a nearby tree. He had to stay guard in case more enemies came by.

Infinite: You all move along. There's more enemies to be done for.

Machito: Hey Clauds. You wanna join our group?

Machito (thoughts): Please say yes. Please say yes!

Clauds: Sure.

Machito (thoughts): Yeah!

JCR: Welcome aboard, Clauds.

Edgellie: Let's kill some more evil dudes.

The male Pikachu came along too, while the female Pikachu and the rest of Meggy's fighting pets stayed with Mario and Meggy while they rest. Infinite stayed watch and made sure something like that will never happen again.
