I will keep the description short, and I will update the list when new ideas come to me. If you like to see any more then other, or have an other ideas feel free to let me know. I also don't mind if people take my ideas to use. Just let me know so I can read them.
WARNING: First time writer and only doing it for fun, and tired of seeing lame fics.
Shadow Slave
1. Oc with Dream related powers, or Fate related powers. Might have a power of each daemon or something, if I choose Dream powers.
2. Sunless Regression or Oc as Sunless. I like the Former better.
3. Sunless and Nephis roles swap.
Naruto
1. Oc reincarnated as an Uzumaki. Same age as Itachi.
2. Two or three Ocs reincarnated in Hashirama and Madara era. In different clans such as Uchiha, Senju, Uzumaki,and Hyuga. Maybe in one of the minor clan like Nara.
Avatar The Last Airbender
1. Oc as Airbender in the Fire Nation.
2. Oc as a Avatar.
3. Oc as a spirit and bender or something. I don't know everything about spirit so some research is need.
My Hero Academia
Same time line, but sets at college instead of Highschool. Most ideas is a Ocs with different powers.
1. DNA Manipulation
2. Energy flux/ Manipulation
3. Space related powers
That Time I Got Reincarnated As A Slime
I don't have a solid idea for this one. I just want to write one. Also I don't think I can write a good one because it might be just like the original.
Demon Slayer
Every fic will have the elemental breathing being real.
1. Oc gets transparent world early.
2. Oc becomes a demon "Demon slayer".
RWBY
Don't have many interesting ides. I need more.
1. Add a new soul power as a next stage of aura like Spiritual Energy(Bleach), Aspects(Shadow Slave), or something I'm still thinking about it.
Bleach
1. Oc power is to make spirit of concepts. Just start reading a Bleach fic called "Bleach: The Eldritch Empire" and it got me thinking of writing something similar.
2. Oc as a hollow. For powers I have no specific ideas.
Danmachi
NO particular idea in mind. Only Oc ideas with different powers.
Fairy Tail
NO particular idea in mind. Only Oc ideas with different powers.
Jujutsu Kaisen
NO particular idea in mind. Only Oc ideas with different powers.
Highschool DXD
Problem is don't know the series will, but was thinking this can be a meta essence fic
Meta essence fic
Just want to write one. "For what series?" No idea. Any series is fine.
