Prologue

My name is Percy Jackson and I am not having a good day. Hell, I have not been having a good time overall for about a year or so now. I honestly can't remember for sure. Can't even bring myself to care about knowing, really. I try to look back over and over again, to try and figure out how exactly it all went wrong. Why any of it went so wrong, and paradoxically it felt like it all happened so fast and so slowly at times. What's that? I'm not making sense? Get to the point? Alright then, I'll do my best.

Whomsoever is paying attention to these thoughts of mine (and in a world where gods and monsters from all mythologies do in fact exist, I am not in any way being sarcastic here), I won't bore you with all the trivial details of my life up to this point. I'mma give you the major points. Try and paint a picture for you of this sad life of mine. I'm not trying to whine about my life being hard or something, because objectively speaking it has been rather trying.

I mean, I have been through so much utter bullshit it would take like, I dunno, two separate book series to cover everything. One series for the rise of Kronos, and one for the rise of Gaia. Not sure why I phrased it all that way, just a feeling I guess…

Anyway, where was I? Ah yes, I'm Percy Jackson and my life sucks. You'd think after everything I have done for the demigod community (and in fact for actual gods themselves) that life would cut me some serious slack. Well, I guess it did. Just not for any length of time I would truly appreciate. You see, after the prophecy of The Seven had finally run its course and Gaia was truly defeated, which prevented the end of everything (although, would the other pantheons beside Greek and Roman have suffered as well? Wouldn't the Egyptian and Norse gods have raised a fuss if Gaia had actually WON? Food for thought…) my life was what once could actually call good.

I ended up finishing a college degree program in marine biology. Annabeth and I were madly in love and in a stable relationship for several months straight without any major incidents (life threatening or not as they were) and all of my friends were living good lives as well. The pandemic barely even registered for me as some sort of setback, having to adjust to mostly staying at home wasn't too bad. But hey, Apollo had reached out to various gods of medicine from all the pantheons with any sort of power and they took care of it. Completely. No more pandemic, things on that front have been well in hand for quite a while now.

I still can't wrap my head around the day things went downhill for me. Annabeth was growing more and more distant, and I had no idea why, and I still don't to this day. Things came to a head when I was heading to our favorite diner on my own that I saw here making out with some guy in OUR usual booth. Didn't have any clue who he was, didn't care.

So of course, I marched up to them. I dragged the guy out of the booth, all the way outside of the damn diner and into the middle of an empty parking space. I just saw red, totally. And I never really had much of a fondness for that color. See: Ares. I beat the shit out of that gods damned bastard. You know how people sometimes describe being so angry they black out and when they come back they see their victim on the ground and have no memory of what exactly they did? Strangely, despite the fact I was pissed off way beyond anything, my mind was totally clear the whole time.

I never said anything resembling coherent words, just snarled and growled at the prick. I punched him straight in the solar plexus, then kneed him in the face when he doubled over losing all air in his lungs, made sure to grab him in the back of the head before he could fall on his back and kept punching with my free hand and kicking him anywhere and everywhere I could reach. It could have been all of ten minutes (felt more like ten hours to me for some reason) before Annabeth got between us and started yelling at me. Cursing me out, telling me to stop before I killed him or some shit…

We broke up right there and then. She screamed at me something along those lines. I yelled curses and whatnot that basically agreed with the sentiment. It was just some sort of twisted domino effect after that. One thing led to another, everyone in my life except for my brother Tyson took Annabeth's side of things and just cut me off from their lives. I was not welcome anywhere. Yeah, even Poseidon didn't want anything to do with me anymore. Tyson was the only one to be on my side. He spoke to me one night, in the Neptune cabin about this whole situation. He told me how it seems like someone or something powerful was conspiring against me. Wanted me isolated from everyone. He also had no clue why he was the only one not being affected by this strange force. And I told him, it didn't matter. It was time I went walking on my own path.

I started traveling not long after that. Going all over the world, doing something I felt I did best: killing monsters. Learned this powerful magic ritual that blocks all forms of magical observation and messaging and whatnot, my anger fueled my desire to learn. Picked up some nifty tricks that I took to calling Signs. Okay fine, I've played The Witcher 3 for more than 800 hours and it stuck with me. Besides the "divination" blocking magic ritual, I did indeed recreate the 5 Witcher Signs through magic. Don't ask how exactly. It doesn't matter.

My recent obsession with The Witcher 3 also led me to commission my brother Tyson for my very own Forgotten Wolf School set, complete with flat Wolf School medallion. I had it done in the Netflix Witcher season 1 style. Both season 1 and 2 look awesome, don't get me wrong, but if I had to choose…Season 1 hits a slightly more badass look for someone with my looks and build. Also had Tyson forge one sword for me, using a solid mix of celestial bronze and the strongest steel he had access to. Then I had it enchanted with reliable Norse runes (thank you Magnus Chase's friends) to increase the durability of the sword and maximize its sharpness to the point of not needing a whetstone for a good while. The whole Forgotten Wolf set of mine gets stored inside the medallion when not in use. Magic not dissimilar to what was done on Riptide. Which I still have and use when the mood or need strikes.

So yeah, I became a wandering monster slayer. Because monster slayer contracts were in fact a thing. Have been for several centuries now apparently. Even if it was only the demigod and magic user communities that needed that sort of help. I only noticed after my split with Annabeth because, well, I had a reason to go looking for that sort of work and finally noticed. With no ancient wars to fight, bullshit dealing with gods, and no toxic relationships (romantic or otherwise) to blind me from these sorts of things anymore.

It was actually really awesome and fun being a wandering monster slayer, a Witcher in profession if not in actual lore in this strange world of mythologies. Until of course, I kept getting less and less lucrative contracts. I was walking to the next nearby magical community in northern Europe when it happened.

There was this huge portal that appeared out of nowhere. Right in front of me. It was like looking at an unstable sphere of pure dark matter littered with the stars of a hundred galaxies or something. Then, as the universe was wont to do with these sorts of situations, it exploded in my face. Pretty sure I blacked out that time.

When I opened my eyes after what felt like a mere moment and an eternity all at once, I realized I wasn't in Kansas anymore. Yeah, I quoted Wizard of Oz, it gets the point across! I was freaking isekai'd! At least it wasn't through dying first…

How do I know I wasn't in my reality anymore? Well, as a demigod that learned some pretty awesome magics, I am especially sensitive to the sort of mystical energies that are given off by the various pantheons of my world. And in this place I found myself in? Most of those energies were gone. The only thing left was some energy from China and Japan if I'm guessing the "flavor" right…

Next thing I realized was, I wasn't alone. There were a lot of people gathered in front of me. Some blue skinned mad scientist, a green skinned femme fatale, a fit redhead girl, a goofy looking blonde guy with a mole rat on his shoulder, and an army of what looks like honest to gods henchmen. They were all staring at me agape, like they were shocked to see me for some reason.

"Um, hi?" I greeted them all with a raised hand. I know, not exactly a cool image I am giving off here. But it's my first time being interdimensionally displaced you know!

It was the blue mad scientist that got his bearings first. "Ahhh! The pan dimensional vortex inducer failed! It was supposed to summon a powerful monster! Not some random guy!" He raved and ranted, kept going actually, and was waving about some metallic cylinder in his right hand.

Okay, Percy, let's summarize right away. I was engulfed in some sort of portal. It brought me to a completely different universe compared to my own. That device in crazy Blue's hand is what brought me here. I do not want to go back to my dimension. My life was lonely back there. This, this could be it… I COULD TOTALLY GET A NEW HONEY HERE!

I was cut off from my line of thought by the sound of giggling… Red and Green were laughing at me? "Ah, did I say that out loud?" I asked my audience in general.

"Yep." Red and Green replied at the same time, in the same tone even, with equally amused and flushed faces. When they realized what happened they looked at each other, back at me, then at Blue, then at Yellow, then back to each other and then at me…

During all that nonsense I saw fit to pull out my medallion form under my white shirt and activate my Forgotten Wolf set. Just in case. Crazy Blue looked like he was about to order his henchmen to attack me. Then, with a quick gesture of my right hand and a shout of "Igni!", the pan dimensional vortex inducer erupted into flames and became pan dimensional slag.

"Shego! Attack Kim Possible and the buffoon! The rest of you, attack that magic using ruffian!" See? Told you he was going to do that.

And that's how the first day of my new life in a different dimension started: with a crazy blue guy ordering his men to attack me for destroying his toy and not being the monster he was looking for, while his hot henchwoman attacked what appeared to be actual vigilante types. Not a bad start, if I'm being perfectly honest.

AN: Another fanfic reader messaged me one day about my interest in writing a Danny Phantom cross with Kim Possible, if I recall. I liked the Percy Jackson crossover idea more when they pitched it. Bonnie x Percy as the main ship is what drove me to get this started. Please be kind in the reviews. XD
