Immortal in DC and Marvel Crossover-Hiatus

(Third Person POV)

Inside a big tent a woman was screaming as if she was in absurd pain, people around her were also speaking very loud things like "Go on you can do it!" yes, the woman was giving birth. Dozens of minutes passed and the entire head finally came out and so on the rest of the body came, a extremely cute baby was being held by that woman, and that baby was our dear protagonist...

(Kassandra POV)

I was going back home after a tiring day of work when suddenly a truck came in my direction, I was able to dodge it but I almost got hit "Fuck I almost died there" I continued to walk but other trucks tried to hit me, 6 in the total. I unlocked my door when I heard a falling noise, I looked up "You gotta be fucking kidding me..." there were hundreds if not thousands of trucks falling from the sky on top of me "Guess it's fate then" I opened my arms and closed my eyes 'At least reincarnate me please' *BOOM BOOM BOOM BOOM* everything was black, I don't know how much time I stayed like that but I felt very happy to hear a voice after a long time, but it didn't last long after I heard what it said "Oh child, you're dead, but I have something else to tell you..." the voice was powerful but I felt I recognize it from somewhere

"What is it God?" I was sure this man was God but

"HA! YOU THOUGHT IT WAS GOD BUT IT WAS ME! DIO!" why does life hate me this much "Calm down its a joke, I threw that much trucks on you because I knew that you wanted to die, a boring life and work, so I will give you the good old 3 wishes, please don't ask questions just say them" apparently even Gods are impatient

"Okay okay, for my first wish I want to be reincarnated in the DC universe, more precisely the Arrowverse (It's the only one I have decent knowledge so if I made on the ones of comics and stuff I would take to long to update) but put some characters from the MCU in it. For my second wish, I want shapeshifting, like Envy from FMA, I also Cheetah's physical capabilities after the mind block removal and Immortality. For my third wish I want to look like Louis Lane more specifically this version" I made a mental image of her and "Dio" nodded

"Okay, good luck in your adventure" everything went black again and I started to hear screams and a lot of chatting, "Stronger! I can already see the head, go go go!" Minutes passed and I was being held by a beautiful woman that was my mother, my name was Kassandra Koenig, a very cool name.

I was getting fed when I realized something very important, what year is it? I didn't specified what time I wanted to be born, that God wasn't very nice so I'm afraid to find out "Haha! I was bored so I just sent you at 10 000 BCA (Before common age or christ) about 500 years more "advanced" agriculture and the Holocene period, this will be the last time we talk kid, you can do whatever you want with the timeline good luck" Dio talked to me telepathically, this fucker, but there's nothing I can do about it so I just need to wait...

(16 years later)

Sixteen years passed in a blink of an eye, I learned how to fight, to use my powers and their language. I was currently hunting as the leader of a group of men, we're all wearing cold coats as we are still on the ice age, it will take about 500 years for it to end. We positioned our selves at the edge of a cliff and waited for mammoth to pass, an hour passed and I heard felt they coming "They are coming" I pointed where I felt them and went there, my hands,feet and fangs were always in the "Cheetah Form" so when I saw one mammoth I jumped off the cliff and fell on its neck, I started to slash and rip his fur to cut his neck open. This day we all had lots of food...

(50 years later)

I was sitting next to my mother, she was in her death bed, in these years I started to love her, she was a caring woman that really loved me, losing her will be very hard but it's part of life, she put her hand in my cheek and pulled me closer until she reached my ear, a voice so low almost like a whisper said "I... love you" tears rolled down my eyes and I grabbed her hand "I love you too mother" this was the day my mother died, I never had a father in both lives, they always died before I was born. I was sad but I knew that this would happen a lot more times in the future.

I left her tent and packed my stuff, I was going on to explore the world...

(15 years later)

It has been 15 years since I went on my exploration, I have no idea where I was the only thing I knew is that I was in a place that wasn't frozen, this warm feeling that I spent 100 years without feeling, I am in some type of tropical jungle with lots of water and plants, after relaxing for hours I got up and made some clothes.

Being in the wild like this is relaxing but boring, fortunately things will get better in a few thousand years...
