You got this thread opened again ...... pretty impressive influence u got there chatte gud work
i didn't know if u read it or not but i thought every one should know this
before that
I dont hate sakura
I'm open to theories based on proof
Now i'll explain why i dont accept your theory with example and what are mainly needed in theories.
Theories are based on proof and there are three steps in a theory (widely accepted in real world)
1. A Base proof
2. Using supporting proof and assumption to extend the base proof
3. Final result or new product
Narutoverse Examples
Theory 1: Sasuke will have perfect susanoo(PS)
Base proof : Sasuke has susanoo
supporting proof or assumption : Only EMS is required for getting Perfect Susanoo
Final Result : since sasuke has EMS he may get Perfect Susanoo
In the above example even though sasuke doesn't have PS yet in manga this theory is more believable and more acceptable (thrust me its not bcos the character is sasuke)
Its more believable bcos the theory takes what sasuke already has (susanoo) and takes it too the next level (perfect susanoo) and there is only one assumption so probability of it happening is 50%
Theory 2: Lee may have "Day Time tiger"
Base Proof : Lee can already open 5 gates (gai told this during fight with gaara)
supporting proof or assumption : Gai will also teach the next 2 gates and teach "Day Time Tiger"
Final Result : Lee may learn "Day Time Tiger"
Again in the above example the character being Lee has nothing to do with believing the theory
Its more beliavable than you theory bcos it takes what Lee already has(5th of 8Gates) and extend it to the next level 7th Gate and Day Time Tiger ..also it has only one assumption so 50% chance
Theory 3: Sakura will become the best medical ninja
Base Proof: Sakura has shown impressive medical ninjutsu finding cure for kakuro
supporting proof or assumption: she will only get better with time and if she was that gud in 16yrs old then in her prime she'll be the best medical ninja
Final Result: sakura may become the best medical ninja
Again this is more belivable because it take what sakura already has(medical ninjutsu) and takes it to the next level...also same as before 50% chance
Reason why i think your theories were not believable (This is my opinion)
you did not base your theory on what sakura has already shown in the manga so your theory did not have the base proof
eg for "Bringer of darkness"
Base proof : Sakura may have already know offensive Genjutsu(this already is an assumption bcos there is no proof for sakura using offensive Genjutsu)
supporting proof or Assumption : sakura is a fast learner ,kakashi told sakura is a genjutsu type , sakura espaced form a genjutsu on her own during chunin exam (these are supporting proof)
tsunade may give sakura the scroll about "Bringer of darkness" (assumption)
sakura will learn it by herself by studying the scroll (assumption)
Final Result : sakura may have Bringer of darkness
you see this is the problem sakura who does not have the base for offensive Gensutsu is given a OP offensive Genjutsu
and more than one assumption so less believable
its the same for slug mode or Yin seal
Slug mode no base proof bcos : sakura haven't shown summoning jutsu which is basic for SM
Yin Seal : again sakura haven't shown anything related to yin seal learning as of yet
all the things you have shown in the thread is supporting proof(like sakura has big forehead and yin seal will be placed in forehead) and assumptions like sakura will learn it or master it
if you can give the theory in the way i've given my theory 1,2,3 it'll be more believable
it would be nice if all those things in your theory came true but its less likely to happen
