you ever thought that he couldn't risk using any major jutsu considering his wife and village was there? put it this way the guy is a jutsu creator even the 3th hokage said it there are many secret that was never show about minato hell, they don't even know all the secret to the reaper death seal either, and again you could say the same for tobi he never showed any major move's either, being granted Hokage and you still think he has little jutsu if not powerfull one's. (give the guy and break he use contact seal breaking tobi control from the fox, save his wife and son as well and did a sealing jutsu(is very clear that kishi didn't want to battle to be a long one due to the fact that his wife just had a baby and needed attending to. give the guy credit for making tobi run and for bloody sakes all of you stop comparing two legend with each other.Because it was battle to the death regardless if it was flashback. If minato had anything else than a rasengan and ftg he would have used it. Why hold back in a life death situation? We saw him against high level shinobi like maadra, bee, forth raikage. I think its easy say we have seen what minato can do.
Minato will always have this hype until guys adimit we have fully seen a full picture of minato' skills.
The other guys we know for certain we havwnt seen all their skills. For example, Like the 2nd/1st/3rd hokages, madara have big questions marks. We know for a fact theres more to come from those shinobi, eg 2nd hokage has good in time-space jutsu. 1st hokage took on madara(ems) + fox. 3rd hokage is said to be lot better in his prime by his summon,,etc etc...
Theres nothing to suggest there's anything else to expect from minato. But more importantly minato wont make anymore appearences in the manga anymore. I hightly doubt we will see him again. There's one chance we could see him and thats a rematch between A and minato as kages as this was hinted at the end of the most recent minato flashback.
Regarding the weaknesses I mentioned.
The key weaknesses of minato is his phyicsal strength which is an intresting condriction because taijutsu is key part of how fights. If the rasengan doesnt work he has limited options. Which isnt the case with the other kages we have seen.
Not willing to say hes weak to genjutsu because one key way to break genjutsu is noticing fine flaws in illusions(Note: reason why the sharingan helps the user in canceling genjutsu), something intellegenice plays a big role in and minato certainly has that.
Also minato relys alot on his time-space jutsu, doesnt have any strong elemental jutsu to speak of. And like I said before if does he would have used it in his death match with madara.
The way I see it minato doesnt have many options to attack. IF the rasengan fails then his most powerful attack cant help him. WHich is a big blow to his rasengan and ftg fighting style, dont get me wrong its is a great combo. But its based purely on the rasengan. And its not a massive rasengan or anything.
The reason why minato's arenal is quite small is because he died young. The sooner guys realise, the sooner guys wont hype him to point of saying things like hes the second strongest shinobi under the so6p.Which is total crap. There are kages ahead of minato as they have lived longer and have more nasty techs at there disposal as a result.
Rasengan and ftg arent the best techs in the ninja world. I Would have thought after all the kages we have seen revived shows that clearly. Minato regared has genius that dosent come around often in a generation. But people need to accept that his development was cut short tragegicly. So u can expect him to be the strongest out there.
The thing with death god and the third, I was just making a hypotheical example. I was just saying no one says for no reason maybe the third hokage didnt have dgt untill in his older days. But for some reason people think madara all of the sudden got time-space jutsu latt]er in his life, where we know nothing about madara to begin with. Its quite puzzling to me thats all.
Its actually far easier to speculate when the 3rd hokage learned the dgt than it is of saying when madara learned/obtained time-space jutsu. Speaking of madara there is one jutsu madara has I think he got after he stole hasihrama powers and thats his phase shift technique. But this something I have thoerised a while, not based on anything concrete.
These are just my opinions btw its okay to debate dude I wont hold anything agaist u with if disagree. No fun otherwise. I really think minato's skills are more or less fully revealed before the time of his untimely death.
I consider myself very fair to characters I try to be methodical as much as possible which comes easy to me because I dont have any favoute characters although I Like gai alot reminds me of DBZ and hes very unque.
Regarding who created the death god technique, we enought evidence to know this technique infact was created by the uzumaki clan.
The trade mark swirl left behind on the user belongs to the uzumaki clan which isn't too surprising, since they were wiped out because their specialty with sealing jutsu. Not to mention Uzumaki Kushina did say she taught the forth hokage sealing techniques who incidentally was the first person we saw use this technique. Also the Raikage speculated Minato would have learned the death god summoning from Uzumaki Kushina. (By the way the cloud village tried to kidnap Uzumaki Kushina).
