Chapter 3 released 10/27/2020


1 year later

It's been roughly a year since my arrival at the Afterlife Resort and started my training to become a hero and this would be the final week of staying here before I head into the new world chosen for me.

In this past year I have developed a slightly more pessimistic and serious outlook to life while fighting countless battles in the arena for both single fights and specials which varied with difficulty and specialization. Right now I was heading back into the Gym to test my skills prior to upgrading anything that needed upgrading and to further hone my skills.

"Initiate Training." I spoke in the middle of the training zone for the Gym. "Please select your opponent." The familiar voice of the training zones A.I. allowing me to select any previous fighter I had faced and ones that have yet to be fought by me. "Select Bloodthorne the Indomitable" My opponent was one of the few that was able to truly push myself and my limits. Garbed in a crimson armor with a white skull painted on the left breastplate, towering over me by a couple feet wielding a large war hammer that was named The Feaster. "Confirmed please select a difficulty from levels 1-15." Level 1-15 or simply 1-3 being easy, 4-8 being hard, 8-10 being impossible and 11-15 being Demon. The reason 11-15 was known as Demon was due to the difficulty it provided which was much harder than actually fighting the opponent themselves. "Level 11" My voice was calm despite my anxiousness for the upcoming fight.

The area in the training zone transformed into a pure black room devoid of anything but myself and my opponent standing in front of me. His crimson armor looked even more demonic than usual due to the setting and his war hammer was in one of his more aggressive positions which was a very versatile one at that. The good news about training here was that I could wait as long as I wanted here and my opponent couldn't do anything as they had to wait for me.

Drawing my new sword, a beautiful two handed long sword golden sword that I had dubbed Storm Splitter, with a sapphire embedded into the pommel of crossguard hilt and edges sharp enough to cut down any that stood in my way, while also donning my new armor which had relatively the same color scheme but with a blue cape and the occasional current of electricity flowing around my armor I was ready.

Charging at my opponent my first thought was to actually dodge backwards and spin to attempt to decapitate the enemy combatant and end the round quickly but that wasn't very feasible. So instead I sidestepped the first swing of the hammer and swung my sword along the calf of the other fighter which cut right through and forced him to stagger following that I kicked him in the stomach and proceeded to stab my sword right into his gut and leave it there before throwing three dirty punches at his face in a way that would make Yang envious.

But luck runs out eventually which was something I had figured out quite early into my stay which allowed me to be ready for the surprise attack of my enemy who took my sword from his gut and attempted to slash me with it. If I was in the Arena and this happened where we can't use our specialized gear, then that may have caught me off guard but I had designed my sword and armor together so that no one could use my own blade against me.

My blade was sent flying away from the both of us as I started to throw different types of punches and kicks at the other combatant starting with a haymaker right into the right side of his face and an upper caught which launched him into the air which I then further chained the combo with a quick front kick which pushed him back and dropped his hammer.

Quickly grabbing the war hammer I proceeded to charge at the other warrior before swinging the hammer over my head repeatedly for an entire minute straight leaving the other fighter's body nothing but a bloody mess.

"Training simulation complete Grade B, would you like to try another?" The A.I. announced as I went to pick up Storm Splitter.

I had once again overcome my limits against one of the most difficult simulation settings once more and it made me content with my progress. Almost a year ago my skill level was immensely pathetic where holding a sword properly was difficult for me, much less fighting a real person.

I was going to upgrade my skills one last time before heading to the Arena for one final fight before heading into my new future.

"No that won't be necessary. End the simulation." I said in response.


The Craft Station was the true jewel of the resort with near unlimited possibilities in it then all other destinations within this realm. My goal was simple; I was going to upgrade anything that could be improved but the most important skill in my possession was the skill that needed to be improved first.

Storm God's Envoy. A very limited skill that was both magical and biological, granting unparalleled power and control over the elements of storms. Costing me over 5000CP this skill was the literal pinnacle of the skill path I had chosen.

Reaching the area that was predominantly for upgrading skills I began to interact with the interface to upgrade my skills. Which was disappointing as I only had enough to upgrade one other skill out of the vast number in my possession.

"Upgrade Storm God's Envoy for 7500CP, Primal Regeneration for 1250CP and Grandmaster's Martial Skill for 1000CP?" The interface questioned me.

"Confirmed" My voice echoed in the area as a loud ding signified the completion of the upgrade.

Now all I had to do was fight my last round in the arena before leaving the resort.


Upon arriving at the arena there was a large board showing a brawl tournament that would start in a few minutes which had interested me ever since arriving here despite never participating in the particular fight.

A brawl tournament was essentially fought without weapons and armor where two random people are chosen out of 100 fighters in total to start where the winner of the first battle must then face two more people. This continues until the fighter is unable to battle and the people that remain end up fighting each other till there are only two or three others to decide points.

That was what I was signing up for, a good final match at the arena. Sprinting towards the registration desk I quickly signed up before heading towards the entrance and taking a blank card that would light up when I was called.

"May the fight begin." The booming voice of the announcer echoed throughout the stadium as two random fighters were selected. I must have waited forty minutes easily before my card lit up with the numbers 22/100.

Walking out to the fight pit I had a sudden burst of nostalgia that was reminiscing of my first fight. The crowds roared with praise, cheering for who they were supporting, the noise all but silent as blood pumped in the ears; it was unlike anything I had ever experienced.

I saw my two opponents, both that were very recognizable to me. The opponent that was heading out with me was a human from a world called Earth named Jacob Pierce who had aspirations of going to Remnant but not a Remnant like mine. He wanted to go to a Remnant where only girls could enlist to the academies and form a harem. That was quite creepy upon hearing that. The fighter that was currently at the center of the arena was a demon known simply as Grim, that's all anyone really knew about him.

Immediately rushing towards the human fighter I knee him in the stomach before elbowing the demon in the nose when he tried to sneak up on me. Analyzing the situation my theory on the human fighter was simple, he was a worse version of Yang when it came to boxing which allowed me to prepare a left hook to his nose. I had not paid attention to the demon contender which cost me two swift kicks to my stomach throwing me to the ground slightly dazed. In my daze the demon defeated the other challenger before he leaped into the air trying to deliver an axe kick to my head. Dodging the lethal kick by rolling I grabbed his leg and pulled him to the ground before getting onto his chest and delivering many painful punches. After laying out haymakers and other punches onto my opponents face I brought my hands together and swung them both down onto his face knocking him out and buying thirty seconds worth of time.

This cycle continued for ten minutes consisting of fighters that were recognizable or ones that weren't recognizable until it was down to me and two others that I recognized because they were two of the champions of previous tournaments. The first one was known as Atlas the Mighty, a rumored demigod who was a renowned champion who has won over 50 monthly tournaments some even allowed the use of powers. The second fighter was the truly terrifying one, Adrian Cross, an immortal warlock from a different Earth than most others. Adrian Cross currently has the most wins compared to anyone else, and judging by the look on Atlas's face we might need a change of clothes by the end of this round.

For an entire minute no one moved but it was obvious that both Atlas and myself were very nervous about this fight. Suddenly Atlas charged towards me intent on throwing a brutal haymaker at me while Adrian ran towards both us and performed a spin kick hitting both of us in the face leaving us off balance. In less than a second Cross was on the demigod hitting him in obscure ways that I wasn't able to comprehend even with Grandmaster's Martial Skill. Leaping to my feet I charged the warlock throwing him to the floor and twisting his arm. But only if I was that lucky, the demigod came behind me and lifted me by the neck which allowed the immortal to kick me in my ribs which also sent me flying into Atlas. Leaping back onto my feet once more I charged both of my contenders and swept their feet from under them before stomping on the demigod's neck which knocked him out leaving me with the immortal warlock.

By the expression on my contender's face he was quite surprised that had just happened before he charged at me prepared to end the tournament once and for all. Dodging the warlock's charge before he twisted around and sent a kick to my back which caused me to stagger. The immortal proceeded to kick me in the temple which knocked me out of the tournament to where they were announcing the results.

"In third place we have Atlas the Mighty who is awarded 700CP" The announcer's voice boomed which caused the demigod to look downcast. "In second place Jaune Arc who is awarded 1000CP" The announcer carried on. Satisfied with my result I began to ponder what could be upgraded with 1000CP before realizing that nothing in my collection could be upgraded due to being maxed out or costly. "In first place Adrian Cross who is awarded 2500CP." The announcer's voice ended which allowed us all to leave.

For me I had to head back to my room to pack. It was time for me to go.


Once all packed I head to where my stay at the resort began with the entity. The entity was always located in his office which was above the personal rooms and that was where I had to go.

Opening the door I headed for a seat and spoke. "I wish to head to a new world now."

"Very well Jaune Arc, have you taken a pick of the world you wish to travel to?" He slowly spoke.

"I have, the world is the superhero world that you picked for me. The Young Justice world was what you called it." I responded back to him.

"I see. Good, are you ready Mr. Arc?" The entity questioned me before immediately opening a portal and sending me to the new world before I could respond.


July 1 2010

On a space station orbiting Earth, a group of heroes were meeting before an alarm started signifying that an intruder had appeared.

"Batman there's an intruder in the observation room." A tall green person in a black suit with a blue cape told a tall man dressed as a bat.

"On it, I'll radio in if I need backup." Batman responded to the Martian.

At the same time on the observation deck a dark blue portal threw out Jaune Arc who looked like he was going to be sick and started walking in a drunken way.

"Who are you?" A man in a bat costume questioned him as he got into a combat position.

"Where am I?" Was all Jaune was able to say before fainting.

Batman pressed a hand to his ear and spoke "Batman to Martian Manhunter, it's just a kid I'm bringing him to the med bay. We can interrogate him later."

"Batman why is this child wearing armor?" The manhunter questioned the detective.

"I'm not sure, but I am getting answers from him when he regains consciousness." Batman retorted.

After dropping Jaune off in the med bay Batman headed towards a computer and contacted a fellow hero.

"Clark, we have a problem get to the Watchtower." The detective told Superman before walking away from the computer.
