This isn't really a proper story, but I like fate and have a bunch of drafts for things in that universe and because of that I have to create my own servant stats with skills as well.
So that is what this will be, just people from other universes as servants. I try and make the stats what they should be, so if they seem high, it's probably because I would put them against high level opponents.
Universes in this are:
Solo levelling
One piece
Black clover
Record of ragnarok
Code geass
And many more!
(Note: please don't hate me if there is something wrong with the servants. I'm not a doe hard fate fan so I might get somethings wrong.)
