the 4th wall

Somewhere at edge of the multiverse, a man thickly covered in black rags and wearing a damaged grey scarf looked at the only wall that prevents other worlds for entering theirs

This wall was known to be the 4th wall, something that keeps worlds separate and in their proper place. Only few number of people know about such thing exists, let alone be able to see it.  But lately, the wall was becoming weak, and things that aren't supposed to be there started to appear
This man knew about this, along with a few other friends. People called this man miller, and many had known his story, the only person in the entire world whose sole purpose was to defend the multiverse to fully break down.
He watched the 4th wall slowly crumble, knowing that it won't be long before chaos will ensue.
Miller's phone rang, he took it his old Nokia cellphone and flipped it open. Miller liked the phone despite its bulkiness because of its durability
"This is miller, anything strange going on there?" Miller asked, knowing who he was talking too
"Nothing much, but we need you here, ASAP" the voice from the phone replied
"What the matter timothy?"
He asked, but the line went dead. He sighed and flicked his fingers, instantly teleporting him to his friend, who was in an advance lab filled with instruments to detect abnormalities in the verse
"Good, you arrived earlier" timothy said, not even glancing at his friend
"Whatever, what do you need? Knowing you, you wouldn't say its urgent unless something really bad happened" he said, sitting on the white marble floor
"I told you, no abnormalities nor destroyed universes. But I have an idea" timothy said, finally looking at miller, "it won't be easy to take on every single error, abnormality, and glitch in the entire multiverse all by yourself once the wall is broken, even if you use your powers into full potential"
Miller looked at him, interested, "so, your saying that, I need a partner, or possibly a team, to help me take on the threats?"
Timothy nodded, "yes, but we would need an army"
"You have the phantoms under your command right? We already have an elite army, what more do we need?" Miller asked
"Yes indeed, but it won't be enough. My men cannot do things that only a few selected...things...can do" timothy replied
Miller nodded in agreement, "so where do you think I will find new recruits?" He asked
"I already have something to in mind..." He ushered miller to follow him, "remember that riolu that you saved some time ago?"
"Yeah, what about it?" Miller asked closely following his friend
"Well, I...more or less modified him" timothy said with a wink, he lead him to a room filled with instruments all connected to a single large tube filled with green fluid. A figure was inside the tube, motionless.
"He now has three types, fighting, ghost, and dark. I also gave him knowledge about the wall and other universes, I even taught him how to talk" timothy bragged
"Wow, you did hell of a lot on him. Well, when do I meet him?" Miller asked, still admiring his friend's work.
"Not yet, he still has a few...attitude problems...to be fixed" timothy said with a hint of uneasiness in his voice but miller took no notice of this, he looked at the gray furred lucario, he smiled in satisfaction

Some time after in somewhere else in the multiverse...

"HOLY FUCKING SHIT" a soldier screamed while watching his comrade torn to shreds. The 401st shock trooper regiment had been deployed to an uncharted zone to map out the area and, if possible, eradicate the infected, but they've never encountered such horrific creatures, as if it was an amalgamation of all their sins.
"What the are these things even?" Grimm asked while pumping 6mm rounds into a mutant's head.
"I don't know, but whatever they are, they don't like people who kill zombies" zodiac joked, he jabbed the but of his rifle to the neck of a mutant, ripping of its head in the process
"How long till we evac from this hell hole?" Clayton asked, who was the leader of the group.
"5 minutes till evac" one of the soldiers shouted, he retreated back to his makeshift barricade in fear of getting his head snapped in half
"5 Minutes!? We won't last that longer against these mo fo's!" Grimm exclaimed, he jabbed a grenade into a zombies stomach and threw it to the God forsaken creatures. A display of fire came out, yet still the monsters prevailed
"Looks like were going to die here" greaves said sadly
"Remember the code, we will die taking a million with us to hell!" Clayton shouted in hopes of raising his men's morale. His soldiers shouted back in joy
"Let's give them one last display of hell!" Zodiac shouted
All of the soldier opened fire, lead slammed into the monster's chests, ripping through flesh and hide. Boat-tailed bullets pierced the creatures heads. Tungsten rounds left massive holes in the demon infested creatures.

For a short while, a spark of hope was seen, yet it was not real. They fought for a long time, yet no one came to rescue them. Clayton watched his men slowly back up to him, slowly he couldn't hear anything, his vision started to blur, the last thing he saw before fainting was....
