Naw, they just do similar things.
Blargh, I'll just
chuck it on Imgur.
Being able to nullify all of Medaka's skills, being able to make Medaka unconscious with a thought, being able to give her any aliment/disease (cancer, heart attack, etc.) with a scratch, and being able to BFR people to a dream world from any stage of their lives by kissing them (meaning, if she uses it on you in the year 2018, she could put you in that place as you were in the year 2012, removing you from the real world in the meantime).
lmao nice. Funnily enough, Medaka does kinda have a defence against people with a defence against their abilities being copied, although not an identical one to Kars' case. While she was initially unable to copy Minuses, as that'd also give her their terrible personalities, she was eventually able to copy them without that drawback.
I think that answer to that's pretty unclear, all things considered. It isn't something she activates, it's kind of like a Beyond but with some better feats of how it works, but worse feats/statements on its source. Makes sense given the connection between these characters' authors.
Medaka's most concrete paths to winning, outside of "idk luck does something lol", are:
- Weighted Words; electricity-based telekinesis, mind manip, memory manip, and body puppetry.
- Five Focus; inflicts diseases/ailments, and heals injuries, via a scratch.
- Encounter; once she activates this, it passively redirects any physical/emotional/mental damage. Since we avoid NLF, the physical part probably wouldn't be very relevant here.
- Scar Dead; once she activates this, it passively re-opens any physical/mental wound those around her have ever received.
- Book Maker; spawns a screw in someone which reduces all of their stats, physical and mental, down to Misogi Kumagawa's level, and removes all of their abilities. The shock of this drop often KOs people.
- All Fiction; the causality manip thing that resurrects her, can also be used to erase a lot of stuff. Temperature (inducing Absolute Zero), a person, the concept of time, laws (letting her do things which were previously rendered impossible due to law manip), people's abilities, memories. While this is said to make those things "as if they never existed", events caused by them existing in the past and memories of them existing still remain.
All-in-all, I see a lot of possibly extremely weird interactions here. I'd wanna untangle those before declaring a winner.
