Muzan Kibutsuji was vibrating with demonic fury. His pristine white suit was covered in Moo-Moo Milk, and Aizen was pointing at him with a finger that was currently glowing with a Level 90 Kido spell.
"I've had enough of your 'Moon-Walk' bullshit, you blood-drinking Mother Fu*!" Deadpool yelled, hiding behind a half-melted Mecha-Pool ear. "Aizen! Hit him with the sparkly cube thing! tum, cover your ears! This reality is about to get its settings changed!"
The Reality Glitch
Aizen unleashed Kurohitsugi (Black Coffin), while Muzan retaliated with a Blood Demon Art that sent a thousand jagged spines through the air. The two powers collided right in the center of the Miltank stampede.
But instead of a giant explosion, the world... stuttered.
ERR-RR-RR-RR.
"What is that sound?!" Goku yelled, clutching his stomach. "It sounds like a dial-up modem having a heart attack!"
Suddenly, the vibrant, 3D grass of the Pokémon world began to flicker. The textures blurred into 16x16 pixels. The round Miltanks began to square off at the edges. The sun in the sky jerked to the left and turned into a perfect, glowing yellow square.
"OH CRAP!" Deadpool screamed, looking down at his hands. "I've seen this before! The server is crashing! We're being downgraded to Java Edition! tum, look at my fingers! I don't have fingers! I just have two rectangular stubs! I'm a high-res LEGO-man!"
Welcome to the Overworld
POP.
The smoke cleared. The Miltank farm was gone. In its place was a vast, endless landscape of perfectly cubic dirt and grass blocks. The trees were oak logs topped with green leaf-cubes.
Muzan was now a tall, pale mob with a very blocky fedora.
Aizen looked like a custom skin that someone had spent way too much time on, though his hairpiece was now a single brown pixel-slab.
Saitama was just a yellow rectangle with a white cape-flap.
"Where... where are the cows?" Saitama asked, looking at a nearby creature that was a white-and-black cube with four stick-legs. It made a very compressed, low-bit Moo sound. "And why is the water made of static?"
"We're in Minecraft, you bald-headed Bih!" Deadpool yelled, jumping up and down (which looked more like he was vibrating vertically). "The physics are gone! The rules have changed! If you want a house, you have to punch a tree! If you want to eat, you have to kill that blocky pig over there!"
The Night is Coming
Aizen tried to move, but he realized he could only walk in straight lines and 90-degree angles. "This... this is an insult to my transcendence. How am I supposed to plan a global conquest when I'm restricted to a 1-meter grid?!"
"Suck it up, Soul Reaper!" Deadpool laughed, holding a Wooden Pickaxe he'd somehow crafted out of thin air. "Look at the sun! It's going down! And in this world, when it gets dark, the 'Hollows' aren't the problem. It's the things that go Ssssss..."
SSSSSSSSS.
A green, armless creature with four tiny legs and a frowning face waddled up behind Muzan.
"What is this green shrubbery?" Muzan hissed, turning around. "Is this another one of your tricks, Wilson?!"
"RUN, YOU GEEZER!" Deadpool screamed. "tum, watch this! It's about to be a 'Thriller' remix!"
BOOM.
The Creeper exploded, taking out Muzan's designer gazebo and half of his blocky legs.
