Both then jumps back hagoromo then used his susanoo Izuku who saw this used his juubi beast form then both clash at each other
(A/N): Just imagine that its the juubi
both then began fighting again at each other trying to overpower the other but there were still on equal footing Izuku then thought of a plan he then made 2 shadow clones and the two clones then went outside of the juubi got far away as possible and began preparing
after a few mins of clashing hagoromo then heard each of his sides rumbling he then saw two clones of Izuku
One clone was in izuku's complete susasnoo form
While the other was using sage art technique true several thousand hands
The two clones then began there attack to hagoromo who was fighting Izuku Hagoromo saw Izuku his grandson smirk but what Izuku didn't know Hagoromo already expected this and turned off his susanoo form and said sometthing the ground then began to rumble and saw the rocks and stones where flying or being pulled above both of Izuku's clone where pulled Izuku who knows now what is happening turn off his juubi form and was shocked he thought he had outsmart his grandfather but he was the one who was outsmarted he then went into his six paths form and form two truth seeking orbs into rods and he began to run towards to Hagoromo, Hagoromo who saw this also prepared and both began clashing at each other each strike causes the dimension to shake a few mins of fighting Izuku notice Hagoromo began to tired out so he used this as opportunity to used his new teachniqueto defeat him Izuku then began to add more chakra to himself and the ground began to shake again but this time it was more violent Izuku was now covered with a blue aura. Hagoromo who saw this knew what was gonna happen and began to cover himself with his chakra but it was too late as he was hit by a blue wave of energy. Izuku called this move chakra override where he gathers every chakra around and began coating it in his body and once all the chakra he had absorbed is in his body is ready he then release it all in one go like a big explosion and when hit your chakra will be sapped renedering you unable to use your chakra for a few mins long enough till izuku kills you. Hagoromo who was on the ground proud of his grandson. izuku had bested him and he was ready Izuku then went immediately to his grandfather
