And minato didn't use any tech but rasengan and he had countless seals and was a genius lol obito still used kamui against minato and had the kyuubi that he learned about from madara that's why I say bringing up his age is irrelevant. And how did u come up with the assumption about Oro and rsm naruto? Lol and how did Hiruzen help against obito?? What are u talking about? And he didn't kill minato omg are u slow? Plus u have no proof it was a rinnegan tech. Momoshiki's rinnegan was already disabled from borutos kunai that's how he got defeated so how would he turn around and use the rinnegan to stop time lmao
1. Minato threw every jutsu he knew at Tobi. Ftg level1,2, and 3
Summoning jutsu, rasengan, barrier, and contract seal. The only the missing is sagemode which he said he wasn't good at it.
2. Rsm to Orochimaru is not an assumption it's an example. You think Minato is superior to a 14 year old kid that fought the whole village. It was Hiruzen that interfered with the kyubi that Tobi was controlling. If it was an older tobi against Minato at that current age, he would be the same as the 4th mizukage by now.
3. Boruto only stopped one rinnegan, he still had another. And when momoshiki came back again, he his rinnegan was not damaged
