A/N: I don't own Penn Zero: Part-Time Hero or any of the shows mentioned

Chapter One: Battleworld

Penn couldn't quite put his finger on it, but he had a feeling that this wasn't going to be a normal mission. Now granted there was nothing about normal his job as a part-time hero of the multiverse, but today something felt off to the teenager and his two friends about zapping off to wherever they where needed.

Mainly because Phyllis was talking to a man who was dressed in all white while he was floating in mid-air.

"Um, Phyllis, I know I say this a lot—but what the heck is going on?" Penn asked, taken aback by the sight before him

The elderly woman and the floating man stopped their conversation and looked in the direction of the trio with an annoyed expression on their faces, acting as if they where being interrupted in the middle of an ordinary conversation. The man in white then gently hovered down to the tree teens, making them feel more apprehensive towards the obliviously powerful newcomer. The man's eyes narrowed at the team as he carefully inspected them, as if he was silently judging them for some sort of prize show.

"So…this is the boy you've told me so much about?" he asked, keeping his eyes locked on the children "I'm not impressed and even less impressed with his friends"

"I'll show you unimpressed!" Sashi snarled as she lunged at the stranger, only to be held back by her friends

"Again I ask: what is going on?" Penn questioned once more as he struggled to hold Sashi back "Who is this guy anyway?"

Before their boss could answer, the stranger spoke up.

"Allow me to introduce myself" he began "I am the Beyonder, and I've come to recruit you and your friends for the ultimate test of good and evil in the universe"

"…Is he serious?" the part-time hero asked Phyllis in disbelief

"Very serious" his boss answered "Beyonder is very powerful being from another universe. He is a living god that can destroy whole world with snap of his fingers"

"And how do you two know each other?" Sashi inquired, calming down from her outburst

"He's on my bowling team" Phyllis answered

"You bowl with an omnipotent being?"

"Yes, makes winning much easier"

"Phyllis has told me all about you three during our games" the Beyonder said "At first I thought nothing of it. In fact, I've seen much more capable heroes do all the things you've done with a tea kettle and a piece of string"

If this wasn't a god that was talking to him, Penn would've punched this jerk right between the eyes or worse sic Sashi on him, but he stayed his anger out of fear of what might happen if he did throw that punch.

"But just the other day, Phyllis told me how you all risked your lives to save the multiverse from absolute destruction" the living god continued "it was then that an idea sparked in my mind"

"This 'ultimate test' right?" the ginger inquired

"Exactly" the Beyonder pointed out "You've shown me that you three are capable of not only competing in my games, but also lead it"

"And what makes you think we'll just say yes?" Sashi asked sharply

"Oh it makes no difference to me if you choose to go or not; I'm not the one being affected by your decision" the omnipotent being stated

With a wave of his hand, the Beyonder activated the portal and showed the teens a thriving planet filled with blue-skinned humanoids like beings living peacefully in their cities. Then with a snap of his fingers, the god-like being summoned several different strange characters to the planet—none of which looked friendly. There was a cat-woman dressed in Egyptian clothing who stated summoned large cats made of fire to hunt and kill anyone they found. Another was skull-faced man with an army of little soldiers with eyeballs for heads. A triangle-shaped being with a small bowtie and top hat on who began incinerate any helpless civilian he found. Among the chaos, the teens could see none other then Rippin and Larry dealing out their own brand of evil on the streets on the alien world.

Penn and his friends watched in absolute horror as more and more villains from the multiverse started to wreck havoc all across the once peaceful planet. The part-time hero glanced over to Phyllis, who he saw look away from her bowling buddy's madness, knowing there was nothing she could do to stop it.

"And now, let us fast-forward to five years in this plant's future" the Beyonder furthered

"You can do that?" Boone said in amazement

"There's nothing I can't do" the living god replied with a smirk before turning his attention back to the planet they where viewing

From what they could see, the alien utopia had now been corroded into a hellish nightmare. The sky was black with smoke and the villains had enslaved the population to do whatever they saw fit. The once proud buildings had been burned to the ground in their place stood factories or prisons created by the legions of wicked ones who had invaded their home.

"As you can see Penn, the villains I have chosen have now carved up this planet into their own separate kingdoms" the Beyonder explained "for five years now they have waged war on one another in a never-ending stalemate to take control of the whole world for themselves"

"Stop this now!" Penn demanded

"I will not" the god-man answered with a superior look in his eyes "Only you and your friends can stop this, and if you succeed, I shall grant you all one wish"

That took Penn aback, could this all-powerful being be the key to giving him what he's always wanted: his parents. However, his mind reeled back to the plight he had just witnessed on the planet that was now ruled by evil. As much as he longed to see his parents, he knew those people on that war-torn planet needed him now more then his mother and farther did.

"So, do you accept the challenge then?" his master of the game asked

"I do" Penn answered bravely

"And so do we" Sashi added on as she and Boone stepped forward "We're not leaving him that planet by himself"

"Yeah, what she said!" Boone said proudly before the violent gave him a 'really?' look "Sorry, it was the first thing that came to my mind"

"Excellent" the Beyonder said with a grin "Then let us be off—to Battleworld!"

With that, a bright flash of white light engulfed the living god and the trio of heroes, leaving Phyllis alone in the theater.

"Good luck…" was all she could say; inwardly fearing that she would never see them again

The next thing Peen and his friends knew, they where now standing in a strange futuristic room filled with a massive computer with what looked like a teleporter next to it. The Beyonder was no where to be found, but the trio had a feeling that the master manipulator wasn't to far from them.

"So does the Beyonder expect just the three of us to fight all of these villains?" Sashi asked her friends

"Of course not, that would be unfair" the omnipotent being's voice replied, despite not being seen "which is why I've given you this place to be your headquarters and this super-computer to summon allies for the upcoming war to give you a chance in this place"

"Why don't you just bring them here yourself?" Penn questioned the empty room as he serched for any trace of the game master

"The choice must be yours and yours alone" The Beyonder elaborated "From here on out, I shall only watch with great interest to see if you're truly the hero Phyllis claims you are"

The room went silent from then on, not single trace of the god-like being was seen or heard from again. Suddenly, the computer switched on and began to display a list of names and images of the villains that now ruled Battleworld and what universe they hailed from. The team of heroic teens careful studied each villain, hoping to understand what they were up against and who they needed in order to stop them.

Rippin and Larry.

Mirage.

Bill Cipher.

Demona.

The Fearsome Five.

Hannibal Mcfist and Viceroy.

Lord Hater.

Dr. Drakken and Shego.

The Huntsmaster.

Magica De Spell and The Beagle Boys.

Dr. Doofensmitz.

Ludo and Toffee.

Don Karnage.

Queen Laa.

"That's…a lot of bad guys" Boone pointed with a nervous gulp

"So what's the plan PZ?" Sashi asked the part-time hero

Penn knew that they where hopelessly outmatched by such an onslaught of evil. He then looked over to the teleporter that the Beyonder and a lightbuld switched on in his head.

"Guys, I think it's time for a little recruitment drive" he replied

And so began the war that would ultimately test the might of both good and evil, a war that would rage all across the war-torn world that would determine the fate of not only Battleworld, but the entire multiverse. This war would bring pain, misery and strife to all who took part in it, but no one would know of this world's aguish, for only only one would observe it all with great amusement.

The Secret Wars had begun.
