After reading "Deadpool Kills the Marvel Universe Again" I decided to write a "Deadpool Kills the DC Universe Again". Disclaimer: I own nothing
Act 1
10 years ago, Earth 8675309, Marvel Multiverse, Baxter Building. Deadpool is restrained as a portal to another universe is opened. Mister Fantastic, Hank Pym, Beast, Black Panther, and Iron Man gather.
Mister Fantastic: Sorry, Wade, but our multiverse has barely recovered from the last Deadpool that went rogue. We can't risk another Deadpool killing everyone. But, luckily, we found a multiverse where you might be of use. And with any luck, you won't be like the other you.
The restrained Deadpool is sent into the portal.
Iron Man: I still object to this.
Mister Fantastic: I am sorry, Tony. But we can't risk Deadpool being here.
10 years later, Earth 42, DC Multiverse, H.I.V.E. HQ. A Suicide Squad consisting of Deadpool, Harley Quinn, Poison Ivy, Boomerang, and Huntress is attacking Brother Blood. They are taking out several H.I.V.E. agents.
Deadpool: Excuse me, sir, you've got a little too much boot in your face.
Harley Quinn: Wade! Brother Blood has the intel we need. Take him down!
Deadpool: Whatever.
Brother Blood: This is an act of terrorism! I have done nothing wrong! I will not die! In fact, I have a trick up my sleeve.
Brother Blood throws a toxic gas bomb at Deadpool and Deadpool inhales every breath of it.
Deadpool: Nice try, Blood. But I am immune to all toxins and poisons, and I mean all of them.
Brother Blood: Maybe so, but I have one last trick up my sleeve.
Just then, Deadpool sees four metahuman time agents. One of them wearing a playing-cards costume, another dressed in brown leaves, another wearing a leather jacket and a gas mask, and another was wearing a white outfit with a crossbow
Brother Blood: My team. The Homicide Squad. Seven-of-Clubs, Poison Oak, Australian Headsman, and Madame Crossbow. Kill the Deadpool Suicide Squad!
Deadpool: Oh no you don't!
Deadpool shoots Australian Headsman in between the eyes, then stabs Poison Oak in the back and cuts of Madame Crossbow's head.
Seven-of-Clubs: Deadpool, the hell are you…
Deadpool stabs Seven-of-Clubs in the chest. He then sees Seven-of-Clubs turn into Harley Quinn, Australian Headsman turn into Boomerang, Poison Oak turn into Poison Ivy, and Madame Crossbow turn into Huntress.
Harley Quinn: Killing… us…
Harley Quinn dies as Deadpool watches Brother Blood's helicopter fly away.
A few hours later, a group of heroes consisting of Nightwing, Batgirl, Red Hood, Black Canary, and Blue Beetle enter H.I.V.E. HQ.
Nightwing: The Deadpool Suicide Squad was here alright. Boomerang, Poison Ivy, Huntress, and Harley Quinn.
Red Hood: No sign of Deadpool. You think he could've done this?
Blue Beetle: I don't think so. There is no clear indication that he was even here.
Black Canary: I beg to differ. He left us a sign.
They look at a Deadpool symbol on the wall saying, "help me".
Batgirl: He was not himself.
Batgirl picks up a metal canister.
Batgirl: I think that Deadpool was manipulated into killing them.
Nightwing: You may be right. Either way we got a serial killer on our hands. Any ideas on where he could be?
Deadpool sits in his apartment eating spaghetti from a can. A metal canister rolls under the doorway, with a note. The canister releases the same toxic gas as before. Deadpool picks up the note.
Themyscira. The Amazonians prepare to imprison Ares in Tartarus. However, a mysterious figure blocks the entryway.
Deadpool: Ladies, up for some volleyball?
Deadpool holds up the head of Medusa and all the Amazonians on Themyscira and Ares turned to stone.
The abandoned Arkham Asylum. Someone is laughing.
Mysterious Voice #1: HAHAHAHAHAHAHAHAHAHAHHAHAH!
Mysterious Voice #2: You promised me Superman!
Mysterious Voice #3: SMASH THE JUSTICE LEAGUE!
Mysterious Voice #4: You promised me the Teen Titans!
A light turns on and it reveals mysterious voices 2, 3, and 4 to be Lex Luthor, Solomon Grundy, and Reverse-Flash.
Mysterious Voice: Patience, my friends. You know, it is a shame about Harley. I am going to miss her. But my point still stands. My gas may be too toxic for everyone else, but not Deadpool. If we keep gassing him, he will do as we say.
Another light turns on revealing the Mysterious Voice to be Joker.
Joker: One by one the heroes will die. And we the greatest villains ever, and every other villain who joins our, Cabal as Deadpool called it, will rule all! HAHAHAHAHAHAHAHAHAHAHAHAHA! HAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA!
