I'm pretty sure Minato created FTG by analyzing Uzumaki seal techniques he learned from his wife.
Did you even read the thread? There is indefinant proof that Tobirama used FTG...
1) The third hokage could have showed him how to since he was a prodigy..Possibly saw his potential and showedh i mthe scroll.
2) I don't see that in his character of being a thief or snoop..Again more then likely the Third Hokage taught him and allowed him access to it the scroll.
3)Highly unlikely I think he was taught and my speculation again it had to be the Third Hokage..Oro possibly since he was experimenting on people and many were missing in the village could have stolen the data from Tobirama's dna or grave(remember shinobi bodies hold alot of jutsu hence they are valuable) Out of revenge for not being appointed 4th Hokage when Hiruzen retired. Yet ur assuming as well that Tobirama taught the White fang..these are jus theories
1) Of all the scrolls to be seen and had he showed him FTG for no particular reason. Remember there is a huge scroll filled with forbidden jusu, which obviously isnt as
fordidden as we all thought it was. The entire village was in a panic when Naruto took the forbidden scroll but he just lets Minato use it, no real reason you just say its a possibility. Which it is, and its a possibility that ill have a heart attack right now. But which is more likely, mine theory or yours. Ill answer this in my thread.
2) And your idea is that Hiruzen show him this forbidden scroll because he was a "Prodigy" but in the ninja handbook Minato graduated from the academy at age 10, kakashi did at age 5. Itachi did at age 7. Orochimaru at age 6 and Jiriaya at age 6. There were other geniuses out there. So now you have to explain what "other than him being a "prodigy"" made Hiruzen chose Minato... which ofcourse you cant because there is no proof of any of this.
3) You say that my theory is unlikely but you havent dont anything to make mine look unlikely, you just introduce an alternate and out of no where say it is more likely than mine even though your "theory" introduces ALOT of question while mine does not. Look up occams razor. Ninjas bodys retain alot of jutsu? Explain this to me as I dont remember this. Ive got no clue why you brought up orochimaru? could you elaborate on the point you made in section, I reread it 3 times and cant grasp how it makes a point and disproves mine.
I added a new section to the thread "Update 2" to further talk on this subject.
