Episode ShaDOH is a prequel tale. We recommend reading through some of the main scenario before reading Episode ShaDOH.

Shadow: Fuck that! It's time to get EDGY!

It was one month before the Doctor took over the world. The first time I encountered him. Yes, I'm saying that even though I didn't directly interact with Eggman at all. Just following the script. Or maybe I'm referring to Infinite. Would be nice if the game made that clear.

Rouge: Shadow, we've got a report from the Intelligence Division. They've located an unknown base of operations that seems to be totally outside the chain of command for Eggman's army.

Shadow: The fuck is this "Intelligence Division"? I thought we were working for GUN.

Rouge: GUN doesn't exist in this world, Shadow. Remember the "two worlds" thing Izuka established? I don't care if it doesn't make sense! Just go with it!

Shadow: Fine… What's the Doctor up to?

Rouge: He seems to be developing some sort of weapon. Omega went up ahead! Go meet up with him!

Shadow: Nah! I'm doing this ALONE!

Rouge: Hehe! Omega said the same thing! You two go together like Chili and Hot Dogs!

Shadow: You're seriously comparing me and Omega to the faker's favorite food? Pathetic! Whatever. I'm on my way!

Stage 1: Unnamed City: Enemy Territory

Shadow: Woah! Why is the city still being destroyed? Isn't this supposed to be a month BEFORE Eggman took over?!

Omega: I'D IMAGINE THAT THE GAME DESIGNERS WERE RUSHED OR TOO LAZY.

Shadow: Of course. And also, THIS IS JUST STAGE 15 FROM THE MAIN CAMPAIGN!

Omega: YUP. DEFINITELY LAZINESS.

Later, Omega mysteriously shuts down.

Rouge: Omega! Omega, respond!

Shadow: What happened? Must've been Infinite, but it would've been nice if the game actually SHOWED US THAT!

'Omega': I AM E-123 OMEGA! THE MOST POWERFUL- *static*

Shadow: What the?!

Second half of level

Shadow: Entirely 2d, level made of crates and platforms… What is this?! Super Mario Maker?!

Beat level

Infinite: HAHA! I beat up the world's most powerful robot!

Shadow: Why wasn't there a cutscene showing you doing that? There's something called SHOW, DON'T TELL!

Infinite: That doesn't matter! Besides, our cutscene budget isI've waited a long time to meet up with you again, Shadow.

Shadow: … Do I know you?

Infinite: You seriously don't remember me?! In that case, it's time I show you my TRAGIC BACKSTORY!

Shadow: Wait. A flashback IN a flashback? That doesn't make any sense!

Infinite: DON'T CARE! IT'S FLACKBACK-CEPTION TIME!

A couple of months before one month before Eggman took over the world.

Stage 2: Mystic Jungle (not to be confused with Mystic Ruins): Eggman's Facility

Shadow: Okay, this is just Stage 14: Aqua Road from the main campaign. Of course. They rushed my episode. Why do I even bother?

Eggman: We've got an intruder! Shadow The Hedgehog has entered the facility! Defense Squad Jackal has already been completely annihilated. All available troops, intercept that blasted hedgehog by any means necessary!

Shadow: Wait. I already beat the Jackal Squad? Aw! Would've been nice if I actually got to do that in gameplay. These designers must've been too lazy to program new enemies.

Eggman: Rrrgh! I went to great pains to get the best mercenaries around, and he STILL totally wrecked the Defense Squad! SHADDDOOWWRRRGH!

Shadow: Hmph. Should've hired some Defense Squads for the Defense Squad, eh, Doctor? Heh. I'll give the writers this. That line was pretty badass!

Later…

Eggman: He's getting deeper into the facility! One of you idiots! STOP THAT HEDGEHOG NOW!

Shadow: How can they stop me? Your robots aren't even attacking me!

Cutscene (because the developers were too lazy to make this a boss battle)

Infinite: You… You destroyed my squad! I'll show you why they call me the ultimate mercenary!

Shadow curb stomps Infinite using Chaos Control even though he doesn't have a Chaos Emerald.

Shadow: Seriously? You're the "Ultimate Mercenary"? Worthless! Don't show your pathetic face around me ever again. *not-Chaos Control*

Infinite: He… He's calling me weak! I'm not weak… I'm not! I'm not weak! I AM NOT WEAK! RRRRRRRAAAAAAAAAAAAAAAGH!

Back to one month before Eggman took over the world. Yes, we're still in a flashback. Totally not confusing!

Infinite: I've only become the way I am because of you, yet you don't remember. But I suppose that's the way it goes.

Shadow: … Are you serious? That's why you went power hungry, and would later control the world six months later?! That's your motivation?! Me calling you WEAK?! I-I-I didn't even directly say that! I just said you were pathetic! But now you're even more pathetic than I thought! You're an immature manchild who can't accept failure! Also, the main campaign tries to convince us that you're a robot! Tails even said that Eggman built you! Yet you turn out to be just some ordinary dude! These writers can't even keep a consistency in their narrative! WHY?! WHY? WHYYYYYYYYYYYYY!?

Infinite: SHUT UP! The point is, you made me into what I am today, and now I'm going to give you the worst nightmare of your life! TAKE THIS!

Stage 3: Green Hill (or Sand Hill? Whatever, it's just Green Hill for the gazillionth time.): Virtual Reality

Shadow notices this looks like another Avatar Stage from the main campaign.

Shadow: I'm not gonna say it…

'Rouge': Shadow, Omega was destroyed three months ago! Get it together!

Shadow goes through another 'Mario Maker' level.

Shadow: Wait… I thought Omega was destroyed during the recon mission…

'Rouge': Probably because it never really happened.

Shadow: WHAT?!

'Omega': Affirmitive. I've never met De-De-defeat! I'M NOT WEAK! I'M NOT WEAK! I'M NOT WEAK!

Shadow: Manchild…

Beaten level

Shadow: What? Where?

Infinite: That was wonderful! This power… It is unrivaled! Not even Sonic will be able to stand against me now! HAHAHAHAHAHAHAHAHAHAHAHAHA!

Roge: Withdraw! The facility's about to collapse!

Shadow: Withdrawing!

And they don't explain what happens to Shadow within the next seven months.

On a certain day in Green Hill, Eggman's army launches a savage attack.

Sonic runs into the city and defeats the very easy to defeat robots who can't even fire.

Sonic: Heya, Baldy McNosehair! I noticed you're the only human in this entire game. Did SEGA just forget they existed or something?

Eggman: Glad you could make it, Sonic! Prepare to die by nostalgia!

Shadow shows up.

Sonic: Shadow?!

Metal shows up.

Sonic: Metal?!

Chaos shows up.

Sonic: Chaos?!

That, uh… red guy… shows up…

Sonic: Uhhh… Bowser?

Zavok: *facepalm* No, you blue idiot! My name is Za-

Everyone: NOBODY CARES!

New villain shows up.

Sonic: I don't know who you are, but I'm taking you down!

Sonic tries to boost into the villain, but he steps to the side.

Tails: He'S fAsTeR tHaN sOnIc!

Sonic: No he's not! He just stepped to the side!

All villains proceed to beat the crap out of him while Tails sits down and watches.

Sonic: Why are you just standing there?! HELP ME!

Tails: No, because I'm too cowardly and OOC to do so.

Sonic: Oh, fuck you!

They beat him down and he goes unconscious.

Tails: SONIC!

Shadow: Nothing different happened? What was the point of that at all? Whatever. If you excuse me, I have some writers and level designers to teach a valuable lesson to.
