Notes:
First I'd just like to mention that every feat in this RT used a minimal amount of Chakra or stamina from Oro. Most high level Ninjutsu and Kinjutsu in this RT use up an incredible amount of Chakra, none of which seem to drain Oro at all.
[1] Naruto at this point is greatly beyond the speed of sound. We know this through speed scaling.
[2] This feat is even more impressive because Orochimaru didn't have use of his arms, unable to fight or even form seals with them. The Third Hokage managed to seal Orochimaru's arms into the Death God before being defeated. Orochimaru partially undid this nerf later, when he possessed his third host body, Gen'yumaru. He fully undid this nerf when he possessed a White Zetsu clone, which is made of Hashirama's cells, giving Orochimaru an extraordinary healing factor, as well as the other benefits that come with having Hashirama's cells. Fortunately he seems to have the same Chakra reserves/stamina across all his bodies, so his Jutsu is consistent.
[3] Naruto at this point is greatly beyond the speed of sound, with strength exceeding Tsunade's. I believe Oro is launched hundreds of meters back because the bridge they were on is around 30-40 meters long, and he was launched roughly 8-10 times the length of the bridge, by my counting method.
[4] This is a low-end outlier. This fight took place after Orochimaru had his arms sealed away, but before he took his new host body.
[5] The Single Rashomon is durable enough to tank Kiba and Akamaru's 'Double Wolf Fang' attack. The Triple Rashomon is almost durable enough to tank an incomplete Tailed Beast Bomb. This puts the Triple Rashomon's breaking point somewhere between a building-busting force and an incomplete (4/9 parts) mountain-busting force.
[6] Manda is his most powerful summon, being able to move and fight at FTE speeds despite his size, being able no-sell this huge fireball (which is easily bigger than a city block, considering the toad on the right is 17 meters tall), with ridiculous durability. Deidara's C0 explosion that he used against Sasuke covers a diameter of 20 kilometers, but Sasuke survived it by summoning Manda to tank the blast for him. While the explosion did kill Manda, it wasn't immediately. He managed to stay alive long enough to curse Sasuke for his actions.
[6 cont.] Later, Kabuto created a clone of Manda. He is, according to his creator, bigger, stronger, and has senses better than the original. Manda II is slightly smaller than the Island Turtle, as seen in the middle right panel. The Island Turtle has no definitive size, but it is easily larger than a city. Manda II was able to wrap himself around it and flip it over. While Manda II is still alive, it is unknown if Orochimaru can summon him.
[7] The snakes bearing Curse Marks can easily destroy buildings, but aren't very durable. A giant frog with similar strength was able to OHKO one of the snakes.
