Kimimaro didnt have a good showing so hes underestimated. Kimimaro can win this. 8 gate is his only threat.
- The bone attack is the strongest physical attack for Orochimaru, one of the strongest.
- It can pierce through the ground and attack at a mass level.
- Combined with the all seeing power, He can time his attacks with precision and pierce Gai when he comes at him with Hirudora which will fail because of the durability of the bones, Orochimaru said Kaguya clan has the strongest bodies and the bones are stronger than steel.
- Hirudora is resisted, Bone pierces gai by extension and if gentle fist is added to list, then rotation bone circus would pierce gai continuously and at the same time stop his 360 chakra points and leave him unable to release his blue aura again.
- Gentle fist + Bone pierce will send chakra into gai's body and destroy his blood vessels and at the same time go through his body, killing him.
